    JANE DOE v. CHARLES COCHRAN
    (SC 19879)
    Palmer, McDonald, Robinson, D’Auria, Mullins,
    Kahn and Vertefeuille, Js.*
    Syllabus
    The plaintiff sought to recover damages from the defendant physician, claim-
    ing that he was negligent in failing to accurately report the positive
    results of a laboratory test for genital herpes to his patient, S, the
    plaintiff’s boyfriend. The plaintiff and S had been involved in an exclusive
    romantic relationship. Before the relationship became sexual, the plain-
    tiff and S agreed to seek testing for sexually transmitted diseases (STDs).
    Prior to this agreement, the plaintiff had tested negative for STDs. S
    then visited the defendant and informed him that he wanted to be
    tested for STDs for the protection of his new, exclusive girlfriend. The
    defendant arranged for S to undergo a blood test, and the results were
    positive for genital herpes. The defendant delegated to a member of his
    practice staff the task of informing S of the test results. The staff member
    incorrectly told S over the phone that his STD test results were negative.
    After the plaintiff’s relationship with S became sexual, the plaintiff
    began to experience outbreaks consistent with and was subsequently
    diagnosed with genital herpes. S thereafter contacted the defendant to
    inquire further, and the defendant informed S that he actually had tested
    positive for genital herpes and apologized for the error. The defendant
    moved to strike the plaintiff’s complaint, claiming that the plaintiff’s
    claim sounded in medical malpractice and, therefore, must fail for lack
    of a physician-patient relationship between the plaintiff and the defen-
    dant. The defendant claimed alternatively that, even if the plaintiff’s
    claim sounded in ordinary negligence, the plaintiff and the defendant
    were not involved in any special relationship that would justify extending
    a duty of care to her. The trial court granted the defendant’s motion to
    strike, concluding that the defendant did not owe a duty to the plaintiff.
    On appeal from the judgment in favor of the defendant, held:
    1. The defendant could not prevail on his claim, as an alternative ground
    for affirming the trial court’s judgment, that, because the plaintiff’s
    complaint sounded in medical malpractice, the lack of a physician-
    patient relationship rendered her claim legally insufficient and, there-
    fore, that the trial court properly struck the plaintiff’s complaint;
    although this court assumed, for the sake of argument, that the plaintiff’s
    complaint reasonably could be read to allege that the defendant commit-
    ted medical malpractice, it concluded that the plaintiff’s allegations
    also reasonably could be understood to sound in ordinary negligence
    because, even though the alleged error occurred in a medical setting
    and arose as a result of a medical diagnosis in the context of an ongoing
    physician-patient relationship, that error was not one involving profes-
    sional medical judgment or skill, as the reading of the test results and
    the communication of those results to S were ministerial tasks that
    required no advanced medical training, and proof that the alleged error
    constituted negligence would not require expert medical testimony or
    the establishment of a professional standard of care.
    2. A health care provider who negligently misinforms a patient, either directly
    or through a designated staff member, that the patient tested negative
    for an STD such as genital herpes owes a duty of care to an identifiable
    third party who is engaged in an exclusive romantic relationship with
    the patient at the time of the STD testing and who foreseeably contracts
    the STD as a result of his or her reliance on the provider’s erroneous
    communication to the patient, and, accordingly, the trial court incor-
    rectly concluded that, as a matter of law, the defendant owed no duty
    of care to the plaintiff with respect to the inaccurate reporting to S of his
    test results: although this court previously has demonstrated a general
    aversion to extending a physician’s duty of care to nonpatients, it has
    allowed, under limited circumstances, for the imposition of liability in
    cases, such as the present one, involving an identifiable potential victim
    who will be foreseeably harmed by a physician’s negligence, and constru-
    ing the plaintiff’s complaint in the light most favorable to sustaining its
    sufficiency, this court concluded that the plaintiff was an identifiable
    potential victim of the defendant’s alleged negligence, as only one person
    could have fit the description of S’s exclusive girlfriend, and S presum-
    ably could have identified her by name if he had been asked by the
    defendant to do so; moreover, a number of other jurisdictions have
    recognized that a duty of a medical professional to correctly advise a
    patient who suffers from a communicable disease, including STDs,
    extends not only to the patient but also to third parties who may fore-
    seeably contract the disease from the patient, and § 311 of the Restate-
    ment (Second) of Torts, which provides that one who negligently gives
    false information may be held liable to a third party who predictably
    is injured by the recipient’s reasonable reliance on that information,
    appeared to support the imposition of liability in this case; furthermore,
    public policy considerations supported the imposition of a third-party
    duty of care under the circumstances of the present case, as imposing
    a duty in this case, in which broader public health concerns are involved,
    would not necessarily intrude on the sanctity of the physician-patient
    relationship, when the duty at issue simply requires a physician to
    accurately relay test results to the patient himself, if the defendant could
    not be held liable, then the plaintiff in all likelihood would be without
    remedy or compensation for her injuries and errors such as the defen-
    dant’s miscommunication would go unadmonished, the defendant,
    rather than the plaintiff or S, was most effectively and economically
    situated to avoid the harm that befell the plaintiff, and such errors are
    not so prevalent or ineluctable that imposing third-party liability, solely
    with respect to identifiable victims, would meaningfully impact medical
    malpractice insurance rates or overall health care costs.

    Opinion
    PALMER, J. The principal issue in this appeal is
    whether a physician who mistakenly informs a patient
    that he does not have a sexually transmitted disease
    (STD) may be held liable in ordinary negligence to the
    patient’s exclusive sexual partner for her resulting injur-
    ies when the physician knows that the patient sought
    testing and treatment for the express benefit of that
    partner. Under the circumstances alleged, we conclude
    that the defendant, Charles Cochran, a physician, owed
    a duty of care to the plaintiff, identified by the pseud-
    onym Jane Doe, even though she was not his patient.
    Accordingly, we conclude that the trial court improp-
    erly granted the defendant’s motion to strike the plain-
    tiff’s one count complaint and reverse the judgment of
    the trial court.
    The following facts, as set forth in the plaintiff’s com-
    plaint and construed in the manner most favorable to
    sustaining its legal sufficiency; see, e.g., Lestorti v.
    DeLeo, 
    298 Conn. 466
    , 472, 
    4 A.3d 269
    (2010); and proce-
    dural history are relevant to our disposition of this
    appeal. In early 2013, the plaintiff began dating her
    boyfriend, identified in this action by the pseudonym
    John Smith. At all relevant times, the plaintiff and Smith
    were involved in an exclusive romantic relationship.
    At some point, the couple agreed that, before their
    relationship became sexual, they would individually
    seek testing for STDs. As of July, 2013, the plaintiff had
    tested negative for and did not have any STDs.
    At that time, pursuant to his agreement with the plain-
    tiff, Smith visited his physician, the defendant, who is
    a licensed medical doctor practicing in Norwalk. During
    Smith’s visit, the defendant asked Smith why he wanted
    to be tested again for STDs, as the defendant had tested
    him just five months earlier. Smith explained that he
    wanted to be tested again for the protection and benefit
    of his new, exclusive girlfriend, the plaintiff. The defen-
    dant then took a sample of Smith’s blood, arranged for
    it to be tested for STDs, and subsequently reviewed the
    laboratory (lab) test results.
    The lab report that the defendant reviewed included
    a guide for reading the test’s results. The guide indicated
    that an HSV 2 IgG (herpes simplex virus type 2 specific
    antibody) result of less than 0.9 is negative for the
    herpes simplex virus type 2 (herpes), a result between
    0.9 and 1.1 is equivocal, and a result greater than 1.1
    means that the sample tested positive for herpes.
    Smith’s HSV 2 IgG test result was 4.43, significantly
    above the threshold for a positive herpes diagnosis.
    The defendant delegated to a member of his staff the
    task of informing Smith of the results of his test. Even
    though the lab report clearly demonstrated a positive
    herpes diagnosis, the staff member incorrectly told
    Smith over the phone that his STD test results had come
    back negative.
    The plaintiff’s relationship with Smith subsequently
    became sexual. Thereafter, the plaintiff began to experi-
    ence herpes outbreaks and was diagnosed with herpes.
    Upon learning of this, Smith contacted the defendant
    to inquire further about his test results. The defendant
    then informed Smith that he actually had tested positive
    for herpes and apologized for the error.
    The plaintiff brought a one count action against the
    defendant, alleging that the defendant had been negli-
    gent in various respects. The defendant moved to strike
    the complaint on the basis that the plaintiff’s claim
    sounded in medical malpractice and, therefore, must
    fail for lack of any physician-patient relationship
    between the plaintiff and the defendant. The defendant
    argued in the alternative that, even if the court con-
    strued the plaintiff’s claim as sounding in ordinary negli-
    gence, the plaintiff and the defendant were not involved
    in any special relationship that would justify extending
    a duty of care to her.
    The trial court granted the defendant’s motion to
    strike. The court did not expressly resolve the issue of
    whether the plaintiff’s claim sounds in ordinary negli-
    gence or medical malpractice, at once describing the
    plaintiff as ‘‘seeking to extend medical malpractice lia-
    bility of a physician to the sexual partner of a patient’’
    and referring to the defendant’s ‘‘claimed negligence
    . . . in reporting the test results.’’ The analysis under-
    taken by the trial court, however, implies that it viewed
    the claim as sounding in ordinary negligence. Specifi-
    cally, the court concluded that the claim was governed
    by our decision in Jarmie v. Troncale, 
    306 Conn. 578
    ,
    
    50 A.3d 802
    (2012), and applied the framework that we
    set out in that case for determining whether a nonpa-
    tient may assert an ordinary negligence claim against
    a health care provider. See 
    id., 591–99. Ultimately,
    the
    trial court concluded the defendant did not owe a duty
    of care to the plaintiff and, for that reason, granted the
    defendant’s motion to strike. This appeal followed.1
    I
    As an initial matter, we must resolve a dispute
    between the parties as to the gravamen of the plaintiff’s
    complaint. As an alternative ground for affirmance, the
    defendant contends on appeal, as he did before the trial
    court, that the plaintiff’s one count complaint sounds
    in medical malpractice. In support of this conclusion,
    the defendant points to, among other things, the facts
    that (1) the plaintiff alleged that ‘‘[the defendant] had
    an obligation to perform the STD tests and [to] report
    the results accurately to . . . Smith according to
    accepted medical practice and standards,’’ (2) the plain-
    tiff further alleged that the defendant’s ‘‘breach of
    accepted medical practice and standards’’ by failing to
    properly treat, test, monitor, and advise Smith, was the
    cause of her injuries, and (3) the plaintiff’s counsel
    attached to the complaint a certificate, pursuant to Gen-
    eral Statutes § 52-190a (a), averring that there were
    grounds for a good faith belief that the defendant had
    committed ‘‘medical negligence’’ in the ‘‘care or treat-
    ment’’ of Smith. Because a medical malpractice claim
    that fails to allege a physician-patient relationship
    between a plaintiff and a defendant is legally insuffi-
    cient; Jarmie v. 
    Troncale, supra
    , 
    306 Conn. 588
    –89; and
    because it is undisputed that the plaintiff never was a
    patient of the defendant, the defendant contends that
    the trial court properly struck the complaint.
    The plaintiff responds that, although she attached a
    certificate of good faith pursuant to § 52-190a (a) out
    of an abundance of caution, her complaint alleges ordi-
    nary, common-law negligence rather than medical mal-
    practice. She notes that the single count complaint is
    titled simply ‘‘negligence,’’ and it alleges that the plain-
    tiff’s ‘‘injuries were the result of the negligence and
    carelessness of the [defendant] . . . in [that he failed]
    to properly advise . . . Smith of his STD test results
    . . . .’’ At no point, moreover, does the complaint use
    the term ‘‘medical malpractice.’’
    A
    We begin our analysis by reiterating that, although
    the better practice may be to include a separate count
    of the complaint for each distinct theory of liability,
    there is no such requirement. Practice Book § 10-26
    provides that, ‘‘[w]here separate and distinct causes
    of action, as distinguished from separate and distinct
    claims for relief founded on the same cause of action
    or transaction, are joined, the statement of the second
    shall be prefaced by the words Second Count, and so
    on for the others . . . .’’ (Emphasis omitted.) In con-
    struing an earlier version of this rule of practice, this
    court explained that it has ‘‘uniformly approved the use
    of a single count to set forth the basis of a plaintiff’s
    claims for relief [when] they grow out of a single occur-
    rence or transaction or closely related occurrences or
    transactions, and it does not matter that the claims for
    relief do not have the same legal basis. It is only when
    the causes of action, that is, the groups of facts [on]
    which the plaintiff bases his claims for relief, are sepa-
    rate and distinct that separate counts are necessary or
    indeed ordinarily desirable.’’ (Footnote omitted.) Veits
    v. Hartford, 
    134 Conn. 428
    , 438–39, 
    58 A.2d 389
    (1948).
    That remains the rule in this state, and it has been
    applied with respect to a single count complaint alleging
    different theories of negligence. See Wheeler v. Beach-
    croft, LLC, 
    320 Conn. 146
    , 160, 
    129 A.3d 677
    (2016)
    (‘‘[e]ven though a single group of facts may give rise
    to rights for several different kinds of relief, it is still
    a single cause of action’’ [internal quotation marks omit-
    ted]); Beaudoin v. Town Oil Co., 
    207 Conn. 575
    , 588,
    
    542 A.2d 1124
    (1988) (restating rule as articulated in
    Veits); Baldwin v. Jablecki, 
    52 Conn. App. 379
    , 382, 
    726 A.2d 1164
    (1999) (statutory and common-law negli-
    gence may be pleaded in single count). Indeed, in Jar-
    mie, on which both parties rely, we treated the single
    count complaint as alleging both medical malpractice
    and common-law negligence when the pleadings were
    substantially similar to those at issue here. See Jarmie
    v. 
    Troncale, supra
    , 
    306 Conn. 583
    –86; cf. Byrne v. Avery
    Center for Obstetrics & Gynecology, P.C., 
    314 Conn. 433
    , 463, 
    102 A.3d 32
    (2014) (reference to violation of
    statutory duty did not transform count of complaint
    alleging common-law negligence into statutory claim).2
    Accordingly, we may assume, for the sake of argu-
    ment, that the defendant is correct that the complaint
    reasonably can be read to allege that he committed
    professional malpractice by failing to follow accepted
    medical standards in his advising, treatment, and ongo-
    ing testing and monitoring of Smith. The question that
    we must resolve is simply whether the complaint also
    alleges that the defendant committed ordinary com-
    mon-law negligence by permitting or instructing his
    office staff to give Smith the wrong test results.3
    B
    The following well established principles guide our
    analysis. First, ‘‘[b]ecause a motion to strike challenges
    the legal sufficiency of a pleading and, consequently,
    requires no factual findings by the trial court, our review
    of the court’s ruling . . . is plenary. . . . We take the
    facts to be those alleged in the complaint that has been
    stricken and we construe the complaint in the manner
    most favorable to sustaining its legal sufficiency. . . .
    Thus, [i]f facts provable in the complaint would support
    a cause of action, the motion to strike must be denied.
    . . . Moreover, we note that [w]hat is necessarily
    implied [in an allegation] need not be expressly alleged.
    . . . It is fundamental that in determining the suffi-
    ciency of a complaint challenged by a defendant’s
    motion to strike, all well-pleaded facts and those facts
    necessarily implied from the allegations are taken as
    admitted.’’ (Internal quotation marks omitted.) Geysen
    v. Securitas Security Services USA, Inc., 
    322 Conn. 385
    ,
    398, 
    142 A.3d 227
    (2016).
    ‘‘In Connecticut, we long have eschewed the notion
    that pleadings should be read in a hypertechnical man-
    ner. Rather, [t]he modern trend, which is followed in
    Connecticut, is to construe pleadings broadly and realis-
    tically, rather than narrowly and technically. . . .
    [T]he complaint must be read in its entirety in such a
    way as to give effect to the pleading with reference to
    the general theory [on] which it proceeded, and do
    substantial justice between the parties. . . . Our read-
    ing of pleadings in a manner that advances substantial
    justice means that a pleading must be construed reason-
    ably, to contain all that it fairly means, but carries with
    it the related proposition that it must not be contorted
    in such a way so as to strain the bounds of rational
    comprehension.’’ (Citation omitted; internal quotation
    marks omitted.) ATC Partnership v. Windham, 
    268 Conn. 463
    , 466 n.4, 
    845 A.2d 389
    (2004).
    Second, our courts have long recognized that a health
    care provider may commit ordinary negligence, as
    opposed to medical malpractice, in the course of treat-
    ing a patient or providing medical services. See, e.g.,
    Multari v. Yale-New Haven Hospital, Inc., 145 Conn.
    App. 253, 260, 
    75 A.3d 733
    (2013) (‘‘The plaintiff has not
    alleged medical malpractice . . . but simply ordinary
    negligence against an entity that happens to be a medi-
    cal provider. The fact that the defendant is a medical
    provider, does not, by itself, preclude a finding that
    the plaintiff’s action sounds in ordinary negligence.’’);
    Badrigian v. Elmcrest Psychiatric Institute, Inc., 
    6 Conn. App. 383
    , 385–86, 
    505 A.2d 741
    (1986) (claim that
    defendant failed to supervise psychiatric patients in
    crossing highway sounded in ordinary negligence); see
    also Jarmie v. 
    Troncale, supra
    , 
    306 Conn. 593
    and n.5
    (leaving open possibility of third-party negligence
    claims against health care providers).
    To determine whether a claim against a health care
    provider sounds in ordinary negligence rather than (or
    in addition to) medical malpractice, we must ‘‘review
    closely the circumstances under which the alleged neg-
    ligence occurred. [P]rofessional negligence or malprac-
    tice . . . [is] defined as the failure of one rendering
    professional services to exercise that degree of skill
    and learning commonly applied under all the circum-
    stances in the community by the average prudent repu-
    table member of the profession with the result of injury,
    loss, or damage to the recipient of those services. . . .
    [M]alpractice presupposes some improper conduct in
    the treatment or operative skill [or] . . . the failure to
    exercise requisite medical skill . . . .’’ (Citations omit-
    ted; emphasis omitted; internal quotation marks omit-
    ted.) Gold v. Greenwich Hospital Assn., 
    262 Conn. 248
    ,
    254, 
    811 A.2d 1266
    (2002). ‘‘[T]o prevail in a medical
    malpractice action, the plaintiff must prove (1) the req-
    uisite standard of care for treatment, (2) a deviation
    from that standard of care, and (3) a causal connection
    between the deviation and the claimed injury. . . .
    Generally, expert testimony is required to establish both
    the standard of care to which the defendant is held and
    the breach of that standard.’’ (Internal quotation marks
    omitted.) 
    Id., 254–55. Accordingly,
    a claim sounds in
    medical malpractice when ‘‘(1) the defendants are sued
    in their capacities as medical professionals, (2) the
    alleged negligence is of a specialized medical nature
    that arises out of the medical professional-patient rela-
    tionship, and (3) the alleged negligence is substantially
    related to medical diagnosis or treatment and involved
    the exercise of medical judgment.’’ (Internal quotation
    marks omitted.) 
    Id., 254. In
    connection with an ordinary
    negligence claim, by contrast, the defendant’s conduct
    is judged against the standard of ‘‘what a reasonable
    person would have done under the circumstances
    . . . .’’ Considine v. Waterbury, 
    279 Conn. 830
    , 859,
    
    905 A.2d 70
    (2006).
    C
    With these principles in mind, we consider the plain-
    tiff’s complaint. The relevant allegations of the com-
    plaint indicate that the defendant reviewed Smith’s test
    results, notified a staff member of those results, and
    delegated to the staff member the task of informing
    Smith of the results. The complaint further alleges that
    the lab report contained a guide that made clear that
    Smith had tested positive for herpes. In addition, the
    complaint alleges that, although the test results were
    positive, the staff member informed Smith that his
    results were negative. Finally, the plaintiff alleges that
    the defendant’s negligence in failing to accurately
    advise Smith of his positive test results caused Smith
    to infect the plaintiff with herpes.
    These allegations are consistent with two distinct
    theories of negligence. First, the defendant could have
    misread Smith’s lab report and incorrectly concluded
    that the results were negative. Second, it is possible
    that the defendant interpreted the report correctly but
    that either the defendant misinformed his staff member
    that the results were negative or the staff member misin-
    formed Smith. In other words, the alleged error could
    have occurred either in the initial interpretation of the
    report or in the inaccurate communication of the
    results, via the staff member, to Smith. See 2 Restate-
    ment (Second), Torts § 311 (2), p. 106 (1965) (negli-
    gence may consist of failure to exercise reasonable care
    in ascertaining accuracy of information or in manner
    in which information is communicated).
    In either case, we agree with the plaintiff that her
    allegations reasonably can be understood to sound in
    ordinary negligence. It is true that the alleged error
    transpired in a medical setting and that it arose as a
    result of a medical diagnosis in the context of an ongo-
    ing physician-patient relationship. There are at least
    two reasons, however, why we nevertheless conclude
    that this aspect of the complaint need not be read to
    sound in medical malpractice.
    First, the alleged error is not one involving profes-
    sional medical judgment or skill. If the defendant mis-
    read Smith’s lab result, then he failed to perform what
    was, in essence, a simple, ministerial task. The index to
    the report states that a result greater than 1.1 indicates
    a positive test, and the report states that Smith’s result
    was 4.43. No advanced medical training was necessary
    to determine that Smith had tested positive for herpes;
    elementary reading and arithmetic skills should have
    been sufficient. Indeed, laypeople routinely perform
    comparable tasks, such as reading and interpreting
    meat thermometers, oil dipsticks, pool and spa test
    strips, and insulin tests.
    Of course, the same conclusion holds to an even
    greater extent if the genesis of the error was that the
    defendant simply told his staff member the wrong test
    result or the staff member relayed the wrong result to
    Smith. That sort of careless miscommunication could
    occur in any setting and has nothing to do with the
    exercise of professional medical judgment or skill.
    Indeed, the very fact that the defendant delegated the
    task to a staff member, who presumably was not a
    medical doctor, points to the nontechnical nature of
    the communication.
    Second, regardless of whether the alleged error arose
    from a misreading or a miscommunication, proving that
    it constituted negligence would not require expert medi-
    cal testimony or the establishment of a professional
    standard of care. A jury will not need expert testimony
    to determine whether the defendant’s staff was negli-
    gent in leading Smith to believe that he was free of
    STDs when the defendant knew, or should have known,
    that Smith had tested positive for herpes, a contagious
    STD, and intended to engage in sexual activity. Such a
    determination is well within the ken of a lay person.4
    Accordingly, we conclude that, as in Jarmie, the
    plaintiff in this case pleaded a cause of action sounding
    in ordinary negligence. We therefore turn our attention
    to the plaintiff’s claim that the defendant, in informing
    Smith of his test results, owed a common-law duty of
    care not only to Smith but also to the plaintiff, a non-
    patient.
    II
    Having concluded that the plaintiff’s claim sounds in
    ordinary negligence, we now must determine whether,
    under the circumstances presented in this case, a physi-
    cian owes a duty of care to an identifiable third party5
    who is not a patient. We conclude that a physician does
    owe such a duty.
    A
    We begin by setting forth the elements of a cause of
    action in ordinary negligence. ‘‘The essential elements
    of a cause of action in negligence are well established:
    duty; breach of that duty; causation; and actual injury.
    . . . Contained within the first element, duty, there are
    two distinct considerations. . . . First, it is necessary
    to determine the existence of a duty, and then, if one
    is found, it is necessary to evaluate the scope of that
    duty. . . . The existence of a duty is a question of law
    and only if such a duty is found to exist does the trier
    of fact then determine whether the [alleged tortfeasor]
    violated that duty in the particular situation at hand.’’
    (Internal quotation marks omitted.) Jarmie v. 
    Troncale, supra
    , 
    306 Conn. 589
    .
    ‘‘Although it has been said that no universal test for
    [duty] ever has been formulated . . . our threshold
    inquiry has always been whether the specific harm
    alleged by the plaintiff was foreseeable to the defen-
    dant. The ultimate test of the existence of the duty to
    use care is found in the foreseeability that harm may
    result if it is not exercised. . . . By that is not meant
    that one charged with negligence must be found actually
    to have foreseen the probability of harm or that the
    particular injury [that] resulted was foreseeable, but
    the test is, would the ordinary [person] in the [alleged
    tortfeasor’s] position, knowing what he knew or should
    have known, anticipate that harm of the general nature
    of that suffered was likely to result . . . .
    ‘‘A simple conclusion that the harm to the plaintiff
    was foreseeable, however, cannot by itself mandate a
    determination that a legal duty exists. Many harms are
    quite literally foreseeable, yet for pragmatic reasons,
    no recovery is allowed. . . . A further inquiry must be
    made, for we recognize that duty is not sacrosanct in
    itself . . . but is only an expression of the sum total
    of those considerations of policy [that] lead the law to
    say that the plaintiff is entitled to protection. . . . The
    final step in the duty inquiry, then, is to make a determi-
    nation of the fundamental policy of the law, as to
    whether the defendant’s responsibility should extend
    to such results.’’ (Internal quotation marks omitted.)
    
    Id., 590. The
    default assumption of the common law, then, is
    that one owes a duty to exercise due care in one’s
    affirmative conduct with respect to all people, insofar
    as one’s negligent actions may foreseeably harm them.
    3 F. Harper et al., Harper, James and Gray on Torts (3d
    Ed. 2007) § 18.6, p. 862. Under specific circumstances,
    however, the law, for reasons of public policy, places
    additional restrictions on the class of people to whom
    a duty of care is owed. See, e.g., 
    id., § 18.3,
    p. 781. In
    most instances, for example, a physician’s liability for
    the negligent care and treatment of a patient does not
    extend to nonpatient third parties who have been fore-
    seeably injured by that negligence. 
    Id., § 18.5A,
    p. 852;
    see also Jarmie v. 
    Troncale, supra

    –93.
    But see Squeo v. Norwalk Hospital Assn., 
    316 Conn. 558
    , 568, 
    113 A.3d 932
    (2015) (recognizing limited cause
    of action for bystander emotional distress resulting
    from medical malpractice); Jarmie v. 
    Troncale, supra
    ,
    593 n.5 (declining to endorse per se rule barring third-
    party claims against health care providers). The present
    case requires us to further clarify the scope of this
    exception to the general duty rule.
    B
    With these principles in mind, we now turn our atten-
    tion to the central question posed by the present appeal,
    namely, whether a health care provider who negligently
    misinforms a patient that he does not have an STD
    owes a duty of care to an identifiable third party who
    foreseeably6 contracts the STD as a result of the provid-
    er’s negligence. The defendant contends that various
    public policy considerations counsel against recogni-
    tion of such a duty. Most notably, because a patient
    such as Smith could have been or become intimate with
    an unlimited number of romantic partners, there is no
    meaningful way to identify or restrict the number of
    individuals whom he might infect and, therefore, to
    limit the class of persons who could have standing to
    bring an action of this sort.
    The defendant further contends that a number of
    public policy considerations and common-law tradi-
    tions that are unique to the health care environment
    or, specifically, to the physician-patient relationship,
    counsel against recognizing a physician’s duty to a non-
    patient third party under the circumstances alleged in
    the present case. He argues that (1) the law generally
    does not impose on physicians a duty of care to nonpa-
    tient third parties, (2) the considerations underlying the
    adoption of Connecticut’s medical malpractice statutes,
    General Statutes §§ 52-190a through 52-190c, disfavor
    the imposition of additional liability on physicians, (3)
    imposing on physicians duties to third parties risks
    interfering with and undermining the physician-patient
    relationship, and (4) considerations of confidentiality
    create both legal and logistical hurdles to the recogni-
    tion of such duties. Finally, the defendant contends that
    the plaintiff could have taken various measures both to
    protect herself from contracting herpes—presumably
    sexual abstention or the use of prophylactics—and to
    establish proper standing to bring an action of this
    sort—such as accompanying Smith when he sought
    treatment from the defendant.
    The trial court, in granting the defendant’s motion to
    strike, was swayed by a number of these arguments.
    The court also discussed several additional concerns:
    whether physicians might become obligated to contact
    and warn or to educate patients’ sexual partners; the
    fact that physicians have no control over whether and
    how patients share their STD test results with potential
    sexual partners; and whether the recognition of a duty
    to nonpatients should be predicated on the existence
    of a formal, mutual STD testing agreement between
    the patient and his or her prospective sexual partner.
    Although the defendant, certain of the amici,7 and the
    trial court raise many valid concerns, for the reasons
    that follow, we are persuaded that they do not counsel
    against the recognition of a duty under the specific cir-
    cumstances presented in this case.
    1
    Setting aside for the moment the question of what
    third-party duties apply within the distinct confines of
    the physician-patient relationship, we observe at the
    outset that many of the concerns that the defendant
    raises and that the trial court found persuasive have
    been addressed and resolved in other professional con-
    texts. Although the plaintiff has not labeled it as such,
    her claim is, in essence, one for negligent misrepresen-
    tation. That tort specifically encompasses situations
    such as this, in which a tortfeasor negligently supplies
    misinformation knowing that the recipient of that infor-
    mation intends to supply it in turn for the benefit and
    guidance of a third party.
    ‘‘This court has long recognized liability for negligent
    misrepresentation. We have held that even an innocent
    misrepresentation of fact may be actionable if the
    declarant has the means of knowing, ought to know,
    or has the duty of knowing the truth. . . . [When the
    information supplied is to be used in the furtherance
    of a business transaction and the alleged harm is solely
    pecuniary, the] governing principles are set forth in
    . . . § 552 of [Volume 3 of] the Restatement Second of
    Torts [1977]: One who, in the course of his business,
    profession or employment . . . supplies false informa-
    tion for the guidance of others in their business transac-
    tions, is subject to liability for pecuniary loss caused
    to them by their justifiable reliance [on] the information,
    if he fails to exercise reasonable care or competence
    in obtaining or communicating the information.’’ (Cita-
    tions omitted; internal quotation marks omitted.) D’Uli-
    sse-Cupo v. Board of Directors of Notre Dame High
    School, 
    202 Conn. 206
    , 217–18, 
    520 A.2d 217
    (1987).
    Recognizing the potentially limitless scope of the finan-
    cial harms that may flow from the dissemination of
    false information, the Restatement (Second) restricts
    liability for negligent misrepresentation of this sort to
    the loss suffered ‘‘(a) by the person or one of a limited
    group of persons for whose benefit and guidance [the
    defendant] intends to supply the information or knows
    that the recipient intends to supply it,’’ and ‘‘(b) through
    reliance upon it in a transaction that he intends the
    information to influence or knows that the recipient
    so intends or in a substantially similar transaction.’’ 3
    Restatement (Second), Torts § 552 (2) (a) and (b), p.
    127 (1977); see also 
    id., comment (a),
    pp. 127–28. In
    other words, the Restatement (Second) addresses the
    problem of potentially limitless third-party liability,
    first, by conferring standing on only those third parties
    to whom the defendant knew that the recipient intended
    to supply the information at issue and, second, by
    restricting liability to losses arising from transactions
    for the purpose of which the information was supplied.
    Defined and cabined in this manner, liability for negli-
    gent misinformation has been upheld in various con-
    texts in which a professional is hired to supply infor-
    mation to a client, knowing that the client is obtaining
    the information at least in part for the benefit and guid-
    ance of some third party or parties. Although we have
    not definitively resolved whether an accountant or an
    auditor may be liable for negligent misrepresentation
    to a nonclient third party; see Stuart v. Freiberg, 
    316 Conn. 809
    , 816–17, 831–32 n.17, 
    116 A.3d 1195
    (2015)
    (deeming it unnecessary to determine whether liability
    could be imposed and leaving question open); a number
    of other courts have held that such professionals can
    be held liable under the approach set forth in § 552 of
    the Restatement (Second) of Torts. See, e.g., Ellis v.
    Grant Thornton LLP, 
    530 F.3d 280
    , 288–89 (4th Cir.)
    (applying West Virginia law), cert. denied, 
    555 U.S. 1049
    ,
    
    129 S. Ct. 652
    , 
    172 L. Ed. 2d 614
    (2008); North American
    Specialty Ins. Co. v. Lapalme, 
    258 F.3d 35
    , 38–40 (1st
    Cir. 2001) (applying Massachusetts law); see also Tri-
    continental Industries, Ltd. v. PricewaterhouseCoop-
    ers, LLP, 
    475 F.3d 824
    , 836 (7th Cir. 2007) (applying
    similar Illinois rule).
    A growing number of courts also have dispensed with
    the traditional privity requirement and have imposed
    liability on attorneys with respect to transactions in
    which the attorney’s opinion is solicited for the benefit
    of an identifiable third party. See generally B. Walker,
    Note, ‘‘Attorney’s Liability to Third Parties for Mal-
    practice: The Growing Acceptance of Liability in the
    Absence of Privity,’’ 21 Washburn L.J. 48 (1981) (noting
    modern trend toward imposing liability and discussing
    cases). Although courts following the modern approach
    to professional negligent misinformation claims have
    not been oblivious to the concerns raised by the defen-
    dant and certain of the amici—the potential for limitless
    third-party liability, interference with the professional-
    client relationship, and the undue burdening of the pro-
    fessional practice—they have concluded that limiting
    liability to circumstances in which professional services
    are sought for the specific benefit of identifiable third
    parties adequately addresses any concerns centering
    around both foreseeability and professionalism. See 
    id., 65–66; see
    also North American Specialty Ins. Co. v.
    
    Lapalme, supra
    , 
    258 F.3d 40
    ; Pelham v. Griesheimer,
    
    92 Ill. 2d 13
    , 20–21, 
    440 N.E.2d 96
    (1982).8
    Moreover, as we discuss more fully in part II B 4 of
    this opinion, the Restatement (Second) of Torts recog-
    nized that there is even less need to cabin potential
    third-party liability for negligent misrepresentation in
    cases such as this, in which the misinformation was
    not supplied for the recipient’s financial benefit and the
    third-party plaintiff suffered physical as well as pecuni-
    ary injuries. Under those circumstances, the Restate-
    ment (Second) advises that ‘‘[o]ne who negligently gives
    false information to another is subject to liability for
    physical harm caused by action taken by the other in
    reasonable reliance upon such information, where such
    harm results . . . (b) to such third persons as the actor
    should expect to be put in peril by the action taken.’’
    2 Restatement (Second), supra, § 311 (1) (b), p. 106.
    Similar principles underlie § 324A, which provides that
    ‘‘[o]ne who undertakes . . . to render services to
    another which he should recognize as necessary for the
    protection of a third person . . . is subject to liability
    to the third person for physical harm resulting from
    his failure to exercise reasonable care to protect his
    undertaking, if (a) his failure to exercise reasonable
    care increases the risk of such harm, or . . . (c) the
    harm is suffered because of reliance of the other or the
    third person upon the undertaking.’’ 
    Id., § 324A
    (a) and
    (c), p. 142.
    2
    Turning to the specific question of what duties, if
    any, a medical professional owes to a nonpatient third
    party, we begin by reviewing Connecticut precedent.
    The parties agree that Jarmie v. 
    Troncale, supra
    , 
    306 Conn. 578
    , is the seminal Connecticut case on the sub-
    ject, but they disagree as to how the present case should
    be resolved under Jarmie.9 We conclude that, although
    Jarmie helps to guide our analysis, whether a physician
    owes a duty of care to a patient’s intimate partner to
    accurately report that patient’s STD test results remains
    a question of first impression in Connecticut.
    In Jarmie, the defendant physician diagnosed and
    treated a patient for various liver and kidney ailments,
    including hepatic encephalopathy but failed to warn
    her of the latent driving impairment associated with
    her condition. 
    Id., 581. After
    leaving the physician’s
    office, the patient lost consciousness while operating
    her motor vehicle and struck the plaintiff. 
    Id. The trial
    court granted the defendant’s motion to strike the plain-
    tiff’s complaint in his subsequent negligence action
    against the physician, concluding that physicians owe
    no common-law duty to protect third parties from injur-
    ies caused by patients. 
    Id., 582. On
    appeal, we began by emphasizing that there is
    no common-law or statutory rule against nonpatients
    bringing ordinary negligence claims against physicians.
    
    Id., 586. We
    recognized, however, that our cases display
    a general aversion to extending a physician’s duty of
    care to nonpatients. See 
    id., 592. That
    aversion is rooted
    in the principles of tort reform underlying § 52-190a, as
    well as the common-law rule that, in the absence of a
    special relationship, there is no duty to protect a third
    person from the conduct of another. 
    Id. We further
    explained that ‘‘[t]here is no well established common-
    law rule that a physician owes a duty to warn or advise
    a patient for the benefit of another person.’’ 
    Id. Never- theless,
    we emphasized that we have not ‘‘employed or
    endorsed a per se rule that [third-party] claims [against
    health care providers] are categorically barred because
    of the absence of a physician-patient relationship but,
    rather . . . this court has exercised restraint when pre-
    sented with opportunities to extend the duty of health
    care providers to persons who are not their patients.’’
    (Internal quotation marks omitted.) 
    Id., 593–94 n.5.
    In
    addition, we distinguished cases from other jurisdic-
    tions that had imposed third-party liability on a physi-
    cian by remarking that those cases, unlike Jarmie,
    involved a physician who had ‘‘failed to warn the patient
    that he or she either had a communicable disease or
    had been exposed to one.’’ 
    Id., 616. Accordingly,
    we
    left open the possibility that, under appropriate circum-
    stances, and in particular with respect to the diagnosis
    of communicable diseases, a physician’s common-law
    duty of care may extend to nonpatients.10
    In the parts of this opinion that follow, we will discuss
    and apply the various factors and considerations that
    we deemed to be relevant to the duty analysis in Jarmie.
    For now, we emphasize two points. First, a principal
    reason that we affirmed the judgment of the trial court
    in Jarmie and declined to recognize that the defendant
    physician owed a duty to the plaintiff motorist was
    because the plaintiff was not an identifiable victim at
    the time that medical services were provided. 
    Id., 590– 91,
    603. Rather, ‘‘potential victims of [the physician’s]
    alleged negligence included any random pedestrian,
    driver, vehicular passenger or other person who hap-
    pened to come in close proximity to a motor vehicle
    operated by [the patient] following her diagnosis.’’
    
    Id., 597. We
    explained that, in previous cases, we had ‘‘limited
    foreseeable victims of a health care provider’s negli-
    gence to identifiable persons . . . .’’ 
    Id., 594; see
    id.,
    596 (‘‘the 
    foreseeability test as applied by this court in
    the context of health care providers has . . . required
    an identifiable victim because we have deemed the
    effect of a physician’s conduct on third parties as too
    attenuated’’); see also Jacoby v. Brinckerhoff, 
    250 Conn. 86
    , 96–97, 
    735 A.2d 347
    (1999) (psychiatrist owed no
    duty to patient’s ex-spouse, who was not identifiable
    victim); Fraser v. United States, 
    236 Conn. 625
    , 632,
    
    674 A.2d 811
    (1996) (psychotherapist owed no duty to
    victim because ‘‘our decisions defining negligence do
    not impose a duty to those who are not identifiable
    victims [and] . . . in related areas of our common law,
    we have concluded that there is no duty except to
    identifiable persons’’).
    In the present case, by contrast, the plaintiff has
    alleged that ‘‘Smith told [the defendant] that he was
    seeking STD testing not only for his benefit, but for the
    protection and benefit of his new, exclusive girlfriend,
    [the] plaintiff.’’ Construing this pleading in the light
    most favorable to sustaining the sufficiency of the com-
    plaint, we must conclude that the plaintiff was an identi-
    fiable, if not identified, potential victim of the defen-
    dant’s alleged negligence at the time that treatment was
    rendered.11 That is to say, only one woman could have
    fit the description of Smith’s exclusive girlfriend, and
    Smith presumably could have identified her by name
    if he had been asked to do so. See Jarmie v. 
    Troncale, supra
    , 
    306 Conn. 597
    –98 (identifiable victim is one
    whom it was possible to identify before negligent act
    occurred).
    This identifiable victim requirement strikes an equita-
    ble balance between the interests at stake. Although a
    health care provider’s liability may expand beyond his
    or her patients, its increased scope would encompass
    only those third-party victims of whose existence and
    potential exposure to harm the health care provider
    had been made aware—or could have become aware—
    prior to the negligent act.12
    Second, since we decided Jarmie, we have held that,
    under limited circumstances, a health care provider is
    liable to third parties for professional negligence, albeit
    in the context of a bystander emotional distress claim.
    In Squeo v. Norwalk Hospital 
    Assn., supra
    , 
    316 Conn. 558
    , we concluded that ‘‘a bystander to medical mal-
    practice may bring a claim for the resulting emotional
    distress . . . when the injuries result from gross negli-
    gence such that it would be readily apparent to a lay
    observer.’’ 
    Id., 560. In
    so holding, we relied on ‘‘our
    recent statement in Jarmie . . . eschewing any per
    se rule that [third-party tort] claims are categorically
    barred because of the absence of a physician-patient
    relationship . . . .’’13 (Citation omitted; internal quota-
    tion marks omitted.) 
    Id., 574. Accordingly,
    we find Connecticut precedent to be
    unsettled with respect to the particular question pre-
    sented here. Although we never have been confronted
    with the question of a physician’s duty to a third party
    with respect to the reporting of STD test results, and
    although we consistently have expressed a general aver-
    sion to extending the duty of health care providers to
    third parties, we have allowed, under limited circum-
    stances, for the imposition of liability to an identifiable
    potential victim who will be foreseeably harmed by a
    physician’s negligence.
    3
    In Jarmie, after we concluded that Connecticut prec-
    edent did not bar the imposition of the duty at issue,
    we proceeded to look to sister state authority and also
    to consider whether various policy factors favored the
    imposition of such a duty. Jarmie v. 
    Troncale, supra
    ,
    
    306 Conn. 598
    –624. In this part of the opinion, we review
    how other jurisdictions have resolved similar cases. In
    part II B 4, we analyze the various policies at issue.
    A number of other jurisdictions have held that, under
    certain circumstances, the duty of a medical profes-
    sional to correctly diagnose and advise a patient who
    suffers from a communicable disease extends not only
    to the patient but also to third parties who may fore-
    seeably contract that disease from the patient. See 61
    Am. Jur. 2d 382, Physicians, Surgeons and Other Healers
    § 226 (2012) (‘‘[a] physician is liable for his or her negli-
    gence in permitting persons to be exposed to infectious
    or communicable diseases to the injury of the persons
    so exposed’’); see also L. Gostin & J. Hodge, ‘‘Piercing
    the Veil of Secrecy in HIV/AIDS and Other Sexually
    Transmitted Diseases: Theories of Privacy and Disclo-

    (1959).14 In some of these cases, the court held that the
    provider had an affirmative duty to notify or educate
    the third party, whereas, in other cases, the court simply
    held that a third party had standing to enforce the pro-
    vider’s duty to properly diagnose, treat, and educate
    the infected patient.
    Although appellate cases addressing a physician’s
    duties to a patient’s premarital sexual partners are few
    and far between, the plaintiff and certain of the amici
    have identified several cases that permit an action to
    be brought either by a victim who was identifiable at
    the time of treatment or by any member of the class
    of persons who foreseeably could contract an STD from
    the patient as a result of the physician’s negligence.
    See, e.g., Reisner v. Regents of the University of Califor-
    nia,

    partner); DiMarco v. Lynch Homes-Chester County,

    B from accidental exposure was member of class of

    spread of that disease, boyfriend had cause of action

    and daughter of patient who was not informed that she
    was at risk of contracting HIV deemed members of
    identifiable class for purposes of hospital’s third-
    party liability).
    The defendant attempts to distinguish these cases on
    the ground that the plaintiff, unlike the sexual partners
    at issue in the cited cases, could have accompanied
    Smith when he sought STD testing and thus established
    a quasipatient relationship with the defendant sufficient
    to support a legal duty of care. We are not persuaded
    by this contention. First, the defendant provides no
    authority to support his theory that either the law or
    the medical profession confers a special status on a
    nonspouse sexual partner who accompanies a patient
    to his or her appointment with a physician and that
    that status is sufficient to support a legal duty of care.
    Second, it may well be that the defendant’s suggested
    approach would interfere more directly with the physi-
    cian-patient relationship and raise more substantial
    confidentiality concerns than would the imposition of
    the third-party duty of care for which the plaintiff
    advocates.
    The defendant also notes that many of these cases
    involve potentially deadly diseases such as HIV that are
    more serious than herpes. We agree with the Alaska
    Supreme Court, however, that ‘‘the duty issue cannot
    turn on possible distinctions among diseases based on
    their severity and ubiquity. . . . Rather, the severity
    and ubiquity of the disease bear on what the [provider]
    must do to discharge the duty.’’ Bolieu v. Sisters of
    Providence in 
    Washington, supra
    , 
    953 P.2d 1240

    A Florida case, Hawkins v. Pizarro, 
    713 So. 2d 1036
    (Fla. App.) review denied, 
    728 So. 2d 202
    (Fla. 1998),
    provides an instructive contrast. In that case, a patient
    tested positive for hepatitis C, but her physician’s office
    improperly advised her that she had tested negative. 
    Id., 1037. Several
    months later, the patient met the plaintiff,
    whom she eventually married. 
    Id. The plaintiff
    con-
    tracted hepatitis C from the patient and filed an action
    against the physician for medical negligence. 
    Id. In upholding
    the trial court’s granting of summary judg-
    ment in favor of the defendant, the District Court of
    Appeal of Florida recognized that hepatitis C is a highly
    contagious sexually transmitted disease and that a phy-
    sician’s duty of care in treating such diseases is intended
    in part for the benefit of third parties. 
    Id., 1037–38. The
    court held that the physician owed no duty to the
    plaintiff, however, because he was neither identified
    nor known to the physician at the time of the incorrect
    diagnosis. 
    Id., 1038. By
    contrast, our research has not
    revealed any cases in which a court held that there
    was no third-party liability under circumstances such
    as those in the present case, in which STD testing was
    obtained expressly for the benefit of an identifiable,
    exclusive romantic partner. But cf. D’Amico v. Delli-
    quadri, 
    114 Ohio App. 3d 579
    , 583, 
    683 N.E.2d 814
    (1996)
    (plaintiff conceded that, under Ohio law, defendant phy-
    sician owed her no direct duty to properly warn and
    advise his patient, plaintiff’s boyfriend, as to communi-
    cability of genital warts).15
    Beyond sister state authority, we further note that
    the Restatement (Second) of Torts appears to support
    the imposition of liability in a case such as this. As we
    previously discussed, § 311 of the Restatement (Sec-
    ond) provides that one who negligently gives false infor-
    mation may be held liable to a third party who pre-
    dictably is injured by the recipient’s reasonable reliance
    on that information. Notably, comment (b) to that sec-
    tion holds up the physician-patient relationship as the
    primary illustration of the rule: ‘‘The rule stated in this
    [s]ection finds particular application where it is part of
    the actor’s business or profession to give information
    upon which the safety of the recipient or a third person
    depends. Thus it is as much a part of the professional
    duty of a physician to give correct information as to
    the character of the disease from which his patient is
    suffering, where such knowledge is necessary to the
    safety of the patient or others, as it is to make a correct
    diagnosis or to prescribe the appropriate medicine.’’
    (Emphasis added.) 2 Restatement (Second), supra,
    § 311, comment (b), p. 106. Accordingly, we conclude
    that sister state and secondary authorities, although
    limited, generally support the imposition of a third-party
    duty under the circumstances alleged in the present
    case. As we discuss in part II B 5 of this opinion, sister
    state courts generally have not been swayed by the
    various practical concerns that the defendant and cer-
    tain of the amici have raised and that the trial court
    found to be compelling.
    4
    Next, because the question presented is one of first
    impression in Connecticut, we consider various public
    policy factors that both this court and other authorities
    have deemed to be relevant to whether and under what
    circumstances a physician owes a duty of care to a
    nonpatient third party. On balance, we conclude that
    those factors support the imposition of a third-party
    duty of care under the circumstances of the present
    case.
    In Jarmie, we identified the following factors, among
    others, as being relevant to the question of what duty
    of care a physician owes to nonpatient third parties:
    the purposes of the tort compensation system, including
    efficiency, harm avoidance, and the appropriate distri-
    bution of loss; Jarmie v. 
    Troncale, supra
    , 
    306 Conn. 599
    –602; the normal expectations of the participants
    in the activity under review and the public policy of
    encouraging participation in the activity, including the
    sanctity of the physician-patient relationship; 
    id., 603– 14;
    and the purposes that underlie Connecticut’s medi-
    cal malpractice statute, § 52-190a, including the avoid-
    ance of increased litigation and higher health care costs.
    
    Id., 592–93, 603,
    614–15. When addressing third-party
    liability in the context of infectious diseases in particu-
    lar, courts also have taken into account such consid-
    erations as ‘‘the foreseeability of third-party injury as
    shown by the patient’s [infectious disease] carrier sta-
    tus, the degree of communicability of the patient’s infec-
    tious disease, and the physician’s actual or constructive
    knowledge of the ease of transmission of the patient’s
    infectious disease; a public health statute [the] legisla-
    tive intent [of which] is partly to protect third parties,
    such as a statute requiring physicians to report diag-
    nosed instances of communicable or infectious dis-
    eases; breach of the physician’s duty to exercise due
    care to protect third parties from foreseeable harm
    as shown by failure to report diagnosed instances of
    communicable or infectious diseases to public health
    authorities, failure to warn the patient with the infec-
    tious disease not to have contact with third parties,
    failure to warn the family of the patient with the infec-
    tious disease about the ease of, and precautions against,
    its transmission, failure to quarantine the patient with
    the infectious disease, failure to vaccinate the patient’s
    family [members] against the infectious disease, con-
    veyance of an affirmative indication that contact with
    the infected patient is not risky, and failure to take
    other reasonable measures to prevent exposure to the
    patient with the communicable disease; additional indi-
    cia of negligence, including failure to use standard avail-
    able tests for diagnosing a patient’s infectious disease,
    failure to interpret diagnostic test results correctly, and
    failure to diagnose the patient’s infectious disease; and
    harm to a third-party plaintiff as shown by the third
    party’s illness from exposure to the physician’s infec-
    tious patient.’’ T. 
    Bateman, supra
    , 
    3 A.L.R. 5th 379
    , § 2
    [b].
    a
    For purposes of the present appeal, two of these
    factors, or sets of factors, are especially pertinent to
    our analysis. First, although we continue to recognize
    the sanctity of the physician-patient relationship and
    the need to exercise ‘‘restraint when presented with
    opportunities to extend the duty of health care provid-
    ers to persons who are not their patients’’; Jarmie v.
    
    Troncale, supra
    , 
    306 Conn. 592
    ; we also recognize that
    such concerns are at their nadir, and a physician’s
    broader public health obligations are at their zenith,
    with respect to the diagnosis and treatment of infec-
    tious diseases.
    Throughout history, both medical organizations and
    government entities have recognized not only the criti-
    cal role that physicians play in combatting the spread
    of contagious diseases such as STDs, but also the con-
    comitant fact that, in diagnosing and treating such dis-
    eases, a physician’s duties and loyalties necessarily
    must be divided between the patient and other people
    whom the patient may infect. See generally L. Gostin &
    J. 
    Hodge, supra
    , 5 Duke J. Gender L. & Policy 9. For
    example, ‘‘one of the earliest recorded public health
    strategies for STD prevention was to pierce the veil of
    secrecy surrounding these hidden diseases by notifying
    sexual partners . . . of infected patients . . . .’’ 
    Id., 11. ‘‘Often
    known collectively as the ‘duty to warn,’
    these [judicially imposed, common-law] obligations sub-
    sequently have been codified by many state legisla-
    tures.’’ 
    Id., 12. For
    example, partner notification mea-
    sures were broadly implemented during the 1930s in
    an effort to control and eradicate the syphilis epidemic.
    
    Id., 21. Many
    states continue to operate provider based
    partner referral programs under which health care pro-
    viders are responsible for contacting, on a confidential
    basis, the sexual partners of patients diagnosed with
    various STDs. See 
    id., 27–32. Indeed,
    even the American Medical Association
    (AMA), one of the amici supporting the defendant’s
    position, which argues against the imposition of a third-
    party duty under these circumstances, has recognized
    that, ‘‘[a]lthough physicians’ primary ethical obligation
    is to their individual patients’’; American Medical Asso-
    ciation, Code of Medical Ethics (2017) opinion 8.4, p.
    128; they also have a responsibility ‘‘to protect and
    promote the health of the public.’’ 
    Id., opinion 8.1,
    p.
    125. ‘‘[P]hysicians must balance dual responsibilities to
    promote the welfare and confidentiality of the individ-
    ual patient and to protect public safety.’’ 
    Id., opinion 8.2,
    p. 126. The AMA has further observed that a physician’s
    ‘‘long-recognized’’ professional responsibilities to non-
    patients are especially pronounced in the context of
    infectious disease, for which professional standards of
    care demand that a physician not only treat his or her
    own patients competently, but also go so far as to ‘‘[p]ar-
    ticipate in implementing scientifically and ethically
    sound quarantine and isolation measures in keeping
    with the duty to provide care in epidemics.’’ 
    Id., opinion 8.4,
    p. 128.
    As we noted, the principle that a physician’s duty to
    protect the broader public health and to help to deter
    the spread of contagious diseases at times transcends
    the physician’s duty to his or her individual patient has
    long been codified in federal and state law. See, e.g.,
    L. Gostin & J. 
    Hodge, supra
    , 5 Duke J. Gender L. &
    Policy 58. Connecticut is no exception in this respect.
    Our legislature has, for example, enacted laws that
    require physicians to test pregnant patients for syphilis
    and HIV; General Statutes § 19a-90; require health care
    providers to report certain communicable diseases to
    local and state public health officials; General Statutes
    § 19a-215; and permit physicians to warn, or to disclose
    confidential patient information for the purpose of
    warning, a known partner of a patient who has been
    diagnosed with an HIV infection or related disease. Gen-
    eral Statutes § 19a-584 (b).
    Perhaps most notably, since 2006, both the United
    States Centers for Disease Control and Prevention
    (CDC) and the AMA have approved the use of so-called
    expedited partner therapy programs to combat the
    spread of STDs.16 Expedited partner therapy ‘‘is the
    delivery of medications or prescriptions by persons
    infected with an STD to their sex partners without clini-
    cal assessment of the partners’’; in accordance with
    this protocol, ‘‘[c]linicians . . . provide patients with
    sufficient medications directly or via prescription for
    the patients and their partners.’’17 The AMA has author-
    ized the use of expedited partner therapy even though
    that approach to treating STDs ‘‘potentially abrogates
    the standard informed consent process, compromises
    continuity of care for patients’ partners, encroaches
    [on] the privacy of patients and their partners, increases
    the possibility of harm by a medical or allergic reaction,
    leaves other diseases or complications undiagnosed,
    and may violate state practice laws.’’ American Medical
    Association, supra, opinion 8.9, p. 132. In other words,
    the medical profession has formed the judgment that
    the need to stem the spread of STDs is so great, and
    the traditional physician-patient model so inadequate
    therefor, that an exception to the prevailing standard
    of care should be drawn so that physicians can provide
    treatment to third parties who are not their patients. Our
    legislature has embraced this novel approach, allowing
    practitioners to dispense oral antibiotic drugs to the
    sexual partners of patients who have been diagnosed
    with chlamydia or gonorrhea, two kinds of STDs, with-
    out first physically examining the partners. See General
    Statutes § 20-14e (e).
    We recognize that none of these laws directly applies
    to herpes. This presumably reflects in part the fact that
    that disease is not curable at present, and, thus, the
    sexual partners of patients infected with herpes would
    not be candidates for programs such as expedited part-
    ner therapy. At the same time, the fact that herpes is
    incurable highlights the extent to which a physician’s
    duties in a case such as this run to third parties as well
    as to the patient, as it will be the patient’s potential
    sexual partners who are the most direct beneficiaries
    of the diagnosis.18
    Perhaps more than in any other field of medicine,
    then, the duty of care that a physician owes to his or
    her patient in the diagnosis and treatment of infectious
    and sexually transmitted diseases also, necessarily,
    entails some duty to third parties who are likely to
    contract the disease from the patient. As the Supreme
    Court of Pennsylvania explained, ‘‘[c]ommunicable dis-
    eases are so named because they are readily spread
    from person to person. Physicians are the first line of
    defense against the spread of communicable diseases,
    because physicians know what measures must be taken
    to prevent the infection of others. The patient must be
    advised to take certain sanitary measures, or to remain
    quarantined for a period of time, or to practice sexual
    abstinence or what is commonly referred to as safe
    sex.’’ (Internal quotation marks omitted.) DiMarco v.
    Lynch Homes-Chester County, 
    Inc., supra
    , 
    525 Pa. 562
    .
    The court continued: ‘‘Such precautions are taken not
    to protect the health of the patient, whose well-being
    has already been compromised, [but] rather such pre-
    cautions are taken to safeguard the health of others.’’
    (Emphasis omitted.) Id.; cf. Davis v. Rodman, 
    147 Ark. 385
    , 391–92, 
    227 S.W. 612
    (1921) (‘‘[o]n account of his
    scientific knowledge and his peculiar relation, an
    attending physician is, in a certain sense, in custody of
    a patient afflicted with [an] infectious or contagious
    disease’’); V. Schwartz et al., Prosser, Wade and
    Schwartz’s Torts: Cases and Materials (11th Ed. 2005)
    p. 432 (custody of persons with contagious diseases
    may give rise to singular duty to control conduct of
    other person).
    At the same time, we perceive little risk that imposing
    a third-party duty under these circumstances would
    interfere with the physician-patient relationship, breach
    patient confidentiality, or require the practice of costly
    defensive medicine. See, e.g., Reisner v. Regents of the
    University of 
    California, supra
    , 
    31 Cal. App. 4th 1203
    .
    Although the plaintiff contends that the defendant owed
    her a duty of care as an identifiable potential victim
    who foreseeably would rely on the accuracy of his diag-
    nosis, her argument is that that duty would have been
    fully satisfied if the defendant simply had provided the
    accurate test results to Smith, his patient. In other
    words, the defendant was under no obligation to con-
    tact the plaintiff, to otherwise ensure that she was made
    aware of Smith’s test results, or to do anything other
    than fulfill his undisputed professional obligation to
    accurately convey his patient’s test results to the patient
    himself.19 The concerns of the dissent that our decision
    in this case will somehow result in the disclosure of
    confidential medical information are, therefore, wholly
    unfounded.
    In conclusion, we think that it is beyond cavil that
    physicians such as the defendant owe some duty of
    care to third parties when diagnosing and treating a
    patient who suffers from an STD. We do not believe
    that imposing the duty for which the plaintiff advocates
    would intrude on the sanctity of the physician-patient
    relationship. Indeed, the duty at issue here—simply to
    accurately relay the patient’s test results to the patient
    —is far more limited and less intrusive than the public
    health reporting and partner notification requirements
    that have been imposed on physicians in the context
    of diagnosing and treating infectious diseases.
    b
    The second set of factors that governs our analysis
    relates to the purposes of the tort compensation system.
    ‘‘[T]he fundamental policy purposes of the tort compen-
    sation system [are] compensation of innocent parties,
    shifting the loss to responsible parties or distributing it
    among appropriate entities, and deterrence of wrongful
    conduct . . . . It is sometimes said that compensation
    for losses is the primary function of tort law . . . [but
    it] is perhaps more accurate to describe the primary
    function as one of determining when compensation [is]
    required. . . . An equally compelling function of the
    tort system is the prophylactic factor of preventing
    future harm . . . . The courts are concerned not only
    with compensation of the victim, but with admonition
    of the wrongdoer. . . . [Of course] [i]mposing liability
    for consequential damages often creates significant
    risks of affecting conduct in ways that are undesirable
    as a matter of policy. Before imposing such liability, it
    is incumbent [on] us to consider those risks.’’ (Citations
    omitted; internal quotation marks omitted.) Jarmie v.
    
    Troncale, supra
    , 
    306 Conn. 599
    –600. In the present case,
    these factors also weigh strongly in favor of imposing
    a duty on health care providers to identifiable and fore-
    seeable third-party victims such as the plaintiff.
    First, we observe that, if the defendant is not held
    liable to the plaintiff under these circumstances, then,
    in all likelihood, she will be without remedy or compen-
    sation for her injuries. It is doubtful, for example, that
    the plaintiff could recover in negligence from Smith,
    who acted responsibly in seeking regular STD testing
    and did not have sexual contact with her until he was
    possessed of a reasonable, good faith belief that he was
    free of STDs.
    The trial court, while recognizing ‘‘the absence of any
    other source of compensation for the [plaintiff’s] harm,’’
    apparently concluded that this factor was mitigated by
    (1) the fact that ‘‘the cost of medical treatment likely
    would be covered by health insurance,’’ and (2) the
    plaintiff’s ability to engage in ‘‘self-protective measures
    . . . .’’ The dissent also is of the view that the plaintiff
    is not without recourse because she ‘‘may well be cov-
    ered by public or private health insurance policies
    . . . .’’
    There is nothing in the record to support the pure
    speculation that the plaintiff had, or will continue to
    have, adequate health insurance.20 Nor do we think
    it is appropriate to expect ordinary health insurance
    policies, or taxpayers, to bear the costs of a physician’s
    negligence. Medical malpractice policies exist to spread
    such costs.
    In any event, the availability of insurance will be of
    little consolation to the plaintiff, insofar as genital her-
    pes is presently an incurable disease. E.g., E. Moore,
    Encyclopedia of Sexually Transmitted Diseases (2005)
    p. 135; Mosby’s Medical Dictionary (8th Ed. 2009) p.
    872. We must assume that, for the remainder of her life,
    the plaintiff will suffer periodic outbreaks of painful
    blisters or ulcers associated with the virus. See, e.g., E.
    Moore, supra, pp. 132–33. Her desirability as a potential
    romantic partner may be diminished. And, if she should
    become pregnant, she will have to contend with the
    risk that she may transmit the virus to her newborn
    child. See, e.g., 
    id., p. 135.
    Some of these injuries will
    not be covered—or may not be adequately covered—by
    medical insurance, and we ought not pretend otherwise.
    Only the defendant can compensate the plaintiff for
    these losses.
    With respect to ‘‘self-protective measures,’’ we pre-
    sume that the trial court was referring to the fact that,
    notwithstanding Smith’s apparently negative STD test
    results, the plaintiff could have further reduced the risk
    that she would contract an STD either by using prophy-
    lactics or abstaining from intercourse with Smith alto-
    gether. Even if we were to assume, for the sake of argu-
    ment, that it would be reasonable and right to expect
    couples, such as the plaintiff and Smith, to abstain from
    sexual intimacy, or to consistently practice safe sex
    while dating, that would only push back the problem.
    At some point, their relationship could have progressed
    to a point at which they would have married and con-
    summated their union. At that point, a wedding band
    would not have been proof against the defendant’s negli-
    gence. See Hawkins v. 
    Pizarro, supra
    , 
    713 So. 2d 1037
    (STD was misdiagnosed prior to courtship, and sexual
    partner was diagnosed after marriage).
    Second, the flip side of the coin is that, if the plaintiff
    cannot hold the defendant responsible for his alleged
    negligence, then errors of this sort will go unadmon-
    ished. Patients such as Smith are unlikely to have
    incurred any legally cognizable damages as a result of
    an incorrect test report and, therefore, may be unable
    to recover from a defendant physician. We recognize
    that not every wrong is compensable in tort and that
    losses, even unjust losses, sometimes must be allowed
    to lie where fate has cast them. See Jarmie v. 
    Troncale, supra
    , 
    306 Conn. 599
    . Under these circumstances, how-
    ever, imposing third-party liability would play an
    important role in spurring physicians such as the defen-
    dant to take greater care in reporting STD lab results.
    As the California Court of Appeal recognized in Reisner
    v. Regents of the University of 
    California, supra
    , 31 Cal.
    App. 4th 1195, the law should ‘‘encourage the highest
    standard of care concerning communicable and infec-
    tious diseases . . . .’’ 
    Id., 1201; see
    also 
    id., 1204 (‘‘we
    believe that a doctor who knows he is dealing with the
    [twentieth] [c]entury version of Typhoid Mary ought to
    have a very strong incentive to tell his patient what she
    ought to do and not do and how she ought to comport
    herself in order to prevent the spread of her disease’’
    [footnote omitted]). Holding the defendant liable to the
    plaintiff would create such an incentive and deter the
    careless misreporting of STD test results.
    The trial court, while recognizing that imposing third-
    party liability under these circumstances could play
    an important deterrent function and help control the
    insidious spread of STDs, expressed concern over what
    it saw as potentially unforeseen consequences. The
    court speculated, for instance, that physicians them-
    selves might feel compelled to discuss lab results with
    their patients, which could be more costly and less
    efficient than relying on nurses or office staff to relay
    results. We do not find this concern compelling.
    A patient who seeks medical attention to be tested
    for a disease, any disease, has a reasonable expectation
    that the test results will be reported accurately, by what-
    ever means. See, e.g., L. Casalino et al., ‘‘Frequency
    of Failure To Inform Patients of Clinically Significant
    Outpatient Test Results,’’ 169 Archives Internal Med.
    1123, 1123 (2009) (‘‘[f]ailures to inform patients of
    abnormal test results . . . are common and legally
    indefensible factors in malpractice claims’’). The risks
    and costs associated with misinforming a patient that
    he does not have a particular disease can be dramatic.
    Those include the direct costs to the patient and the
    health care system, as when, for example, treatment of
    a serious illness such as cancer is irremediably delayed,
    or, as in the present case, through the inadvertent infec-
    tion of third parties by a patient who falsely believes
    that he is free of STDs. Holding health care providers
    responsible for errors of the sort alleged will help to
    maintain public trust in the reliability of the STD
    reporting system and, therefore, encourage continued
    participation in this important public health regimen.21
    Of course, it ultimately will be for the jury to deter-
    mine whether a reasonable health care provider would
    have reported Smith’s test results differently, whether
    through direct physician-to-patient communications or
    through the use of additional fail-safes and quality assur-
    ance measures. But we certainly are not prepared to
    say, as a matter of law, that, whatever added costs
    might be entailed by a quick telephone call or a letter
    from one’s physician, or a policy requiring office staff
    to double check that they are reporting test results
    accurately, they are too onerous relative to the human,
    financial, and public health costs associated with a false
    negative report.22 Cf. Reisner v. Regents of the Univer-
    sity of 
    California, supra
    , 
    31 Cal. App. 4th 1200
    (it is
    not unreasonable to expect physicians to give additional
    warning or warnings).
    Along these same lines, we note that it would not be
    unreasonable for a jury to conclude that the defendant,
    and not the plaintiff or Smith, was most effectively and
    economically situated to avoid the harm that befell the
    plaintiff. In this era of technologized medicine, the con-
    veyance of lab results is a regular and central compo-
    nent of a physician’s professional duties. The physician
    has exclusive access to the original lab results, until
    such time as they are shared with or conveyed to the
    patient. As between the defendant, on the one hand,
    who can avoid errors of this sort simply by double
    checking the results before or after speaking with the
    patient; see L. Casalino et 
    al., supra
    , 169 Archives Inter-
    nal Med. 1123 (discussing ‘‘relatively simple’’ best prac-
    tices); and Smith and the plaintiff, on the other, who
    could ensure that the plaintiff remained free of STDs
    only by permanently abstaining from intimate contact,23
    a jury reasonably could conclude that the defendant
    was the party who was in the best position to avoid
    the harm at the lowest cost and, therefore, should bear
    the costs of the loss. See, e.g., Rodi Yachts, Inc. v.
    National Marine, Inc., 
    984 F.2d 880
    , 883–84, 888 (7th
    Cir. 1993).
    At the same time, physicians such as the defendant
    can most readily bear and spread through malpractice
    insurance the costs associated with errors of the sort
    alleged. We are not convinced that such errors are both
    so prevalent and so ineluctable that imposing third-
    party liability, solely with respect to identifiable victims,
    will meaningfully impact insurance rates or overall
    health care costs.24 For these reasons, we conclude that
    the relevant policy considerations weigh heavily in
    favor of allowing liability under these circumstances.
    5
    Finally, we address two concerns that the defendant
    and certain of the amici have raised and that the trial
    court found compelling. First is the slippery slope issue.
    The trial court observed, and we agree, that, ‘‘[i]n a
    sense, [the] plaintiff’s complaint identifies a best case
    scenario . . . .’’ That is to say, the plaintiff and Smith
    were involved in an exclusive romantic relationship at
    the time Smith sought STD testing, Smith informed the
    defendant that he was seeking testing for the benefit and
    protection of the plaintiff, and the plaintiff subsequently
    agreed to engage in sexual relations with Smith in reli-
    ance on the test results as reported to Smith. This means
    that the defendant’s potential liability for negligently
    misreporting Smith’s test results extended to at most
    one nonpatient third party, a party of whose existence
    the defendant was aware at the time of treatment, who
    could foreseeably contract a contagious STD if an erro-
    neous negative test result were reported, and to whom
    he owed no independent duty beyond the duty already
    owed to Smith to accurately report his test results.
    Nevertheless, the trial court expressed concerns that
    imposing a duty under these limited circumstances
    could open the floodgates. For example, the court ques-
    tioned whether, if Smith had been dating multiple
    women at the time, or later began to date other women,
    with whom Smith had not discussed STDs, the defen-
    dant would owe a duty to a large and ill-defined class
    of potential plaintiffs. The trial court also questioned
    whether, under different circumstances, a physician
    such as the defendant might feel compelled to question
    a patient regarding his sexual partners, or to contact
    those partners to discuss the patient’s STD status, or
    at least to ensure that the patient accurately relayed
    the test results to all of his sexual partners. Finally,
    the court questioned whether it makes sense to make
    liability hinge on the sort of mutual STD testing arrange-
    ment to which the plaintiff and Smith agreed.
    Beginning with the last point, we emphasize that the
    defendant’s liability does not hinge on the fact that
    Smith and the plaintiff entered into a mutual testing
    agreement. The alleged fact that Smith sought and
    obtained STD testing at the time could become relevant
    at trial only insofar as it would support the plaintiff’s
    theory of causation, that is, that she was free of STDs
    until she became intimate with Smith during or after
    July, 2013.
    Beyond that, we emphasize that the duty that we
    recognize today is quite limited. It extends only to iden-
    tifiable third parties who are engaged in an exclusive
    romantic relationship with a patient at the time of test-
    ing and, therefore, may foreseeably be exposed to any
    STD that a physician fails to diagnose or properly
    report. And the physician fully satisfies that third-party
    duty simply by treating the patient according to the
    prevailing standard of care and accurately informing
    the patient of the relevant test results. See, e.g., Reisner
    v. Regents of the University of 
    California, supra
    , 
    31 Cal. App. 4th 1203
    ; Pate v. Threlkel, 
    661 So. 2d 278
    ,
    281–82 (Fla. 1995); Estate of Amos v. Vanderbilt Univer-
    
    sity, supra
    , 
    62 S.W.3d 138
    . Whether there are other,
    broader circumstances under which a physician may
    be held to owe a duty of care to a nonpatient third
    party who foreseeably contracts an infectious disease
    as a result of the physician’s negligence is a question
    that we need not resolve today.
    Nor, as we have discussed, are we overly concerned
    that our recognition of a duty under the specific circum-
    stances of this case will create a flood of litigation,
    increase insurance costs, or discourage physicians from
    offering STD testing. See, e.g., Bolieu v. Sisters of Provi-
    dence in 
    Washington, supra
    , 
    953 P.2d 1239
    . The amici
    supporting the defendant’s position have given us no
    reason to believe that errors of the sort alleged are
    commonplace or that they cannot readily be avoided
    by cost-effective quality assurance measures. As the
    California Court of Appeal explained in rejecting such
    arguments, ‘‘[a]rguments premised on opened flood-
    gates and broken dams are not persuasive [when] . . .
    we suspect that only a few drops of water may spill onto
    a barren desert.’’ Reisner v. Regents of the University
    of 
    California, supra
    , 
    31 Cal. App. 4th 1204
    . And, of
    course, if the legislature perceives differently the risk
    that conferring standing on individuals such as the
    plaintiff will result in a health care funding crisis, then
    nothing bars that body from imposing whatever restric-
    tions it deems prudent on common-law actions of
    this sort.
    Second, we do not share the trial court’s concern that
    recognizing a third-party cause of action for negligent
    misreporting of STD test results would be impractica-
    ble. The court reasoned that, in many such instances,
    a patient such as Smith and an alleged victim such as
    the plaintiff will no longer be romantically involved by
    the time an action reaches the trial stage and, therefore,
    that key evidence—the patient’s medical records—may
    not be available. The court noted that federal and state
    privacy laws could bar a plaintiff from obtaining and
    presenting such records without the patient’s consent
    and that the patient might have little incentive to dis-
    close such records to a former partner and have his or
    her medical and sexual history become part of the pub-
    lic record. The court also appeared to suggest that, in
    cases in which the patient does cooperate with the
    plaintiff, the patient might agree to selectively provide
    only those records that supported the plaintiff’s case,
    leaving the physician unable to defend himself or
    herself.
    Although we do not discount the possibility that the
    concerns that the trial court raises could present logisti-
    cal hurdles in some other case, those hypothetical chal-
    lenges do not counsel against allowing the plaintiff to
    hold the defendant accountable in a case such as this,
    in which the plaintiff apparently will have full access
    to the medical records necessary to put on her case.25
    As we noted in Jacoby v. 
    Brinckerhoff, supra
    , 
    250 Conn. 86
    , ‘‘evidentiary constraints at trial do not, themselves,
    affect the sufficiency of a stated cause of action
    . . . .’’26 For all of the foregoing reasons, we hold that
    the trial court incorrectly concluded that, as a matter
    of law, the defendant owed no duty of care to the plain-
    tiff with respect to the reporting of Smith’s STD test
    results.27
    The judgment is reversed and the case is remanded
    for further proceedings according to law.
    In this opinion D’AURIA, MULLINS and VERTE-
    FEUILLE, Js., concurred.
    * This appeal originally was argued before a panel of this court consisting
    of Justices Palmer, McDonald, Robinson, D’Auria, Mullins, and Kahn. There-
    after, Justice Vertefeuille was added to the panel. Justice Vertefeuille read
    the briefs and appendices, and listened to a recording of the oral argument
    prior to participating in this decision. The listing of justices reflects their
    seniority status on this court as of the date of oral argument.
    1
    The plaintiff appealed to the Appellate Court from the trial court’s judg-
    ment, and we transferred the appeal to this court pursuant to General
    Statutes § 51-199 (c) and Practice Book § 65-1.
    2
    We note that the defendant could have filed a request to revise; see
    Practice Book § 10-35; in order to separate out and separately address the
    plaintiff’s medical malpractice and common-law negligence claims, but did
    not do so.
    3
    As we discuss in part II of this opinion, the plaintiff’s allegations may
    fit most neatly under the rubric of negligent misrepresentation. Because
    neither party has addressed the issue, however, we need not determine
    whether the allegations in the complaint are legally sufficient to plead a
    cause of action in negligent misrepresentation under the law of this state.
    4
    It is true that there are rare circumstances in which expert testimony
    may not be necessary to establish that medical malpractice has occurred,
    such as when a surgeon leaves a surgical implement inside a patient after
    completing an operation. Such gross negligence may be assessed by a jury
    without reference to the prevailing standard of professional care. See, e.g.,
    Squeo v. Norwalk Hospital Assn., 
    316 Conn. 558
    , 580, 
    113 A.3d 932
    (2015).
    This is not such a case because, among other reasons, the alleged error did
    not involve a failure on the part of the defendant to exercise that degree
    of professional skill or judgment that a reasonably prudent health care
    provider would have exercised under the circumstances.
    5
    It is not clear from the complaint whether Smith allegedly told the
    defendant the plaintiff’s actual name or simply indicated that he had an
    exclusive girlfriend for whose benefit he was seeking STD testing. Our
    analysis would be the same regardless of whether the plaintiff was actually
    identified to the defendant by name or merely remained identifiable on the
    basis of Smith’s description of her as his exclusive girlfriend.
    6
    The trial court determined, and we agree, that a jury reasonably could
    find that ‘‘it is foreseeable that a sexual partner of a patient who erroneously
    had been told that he did not suffer from any STDs might contract the STD
    with all of the health related consequences of such an illness.’’
    7
    We granted permission for the following groups to submit amicus briefs:
    the Connecticut Trial Lawyers Association, in support of the plaintiff; and
    the American Medical Association, the Connecticut Hospital Association,
    and the Connecticut State Medical Society, in support of the defendant.
    8
    We emphasize that the question of negligent misrepresentation is not
    before us, and we express no opinion as to whether Connecticut law recog-
    nizes a third-party cause of action in negligent misrepresentation against
    attorneys, accountants, auditors, or medical professionals. See footnote 3
    of this opinion. Our point is simply that the concerns that the defendant
    and the dissent raise regarding potentially limitless liability are the same
    concerns that have been raised, and satisfactorily addressed, in various
    professional contexts across many jurisdictions.
    9
    Neither party advocates that we overrule or reconsider Jarmie.
    10
    The dissent, while conceding that this remains an open question under
    Jarmie, fails to note that, in Jarmie, we specifically distinguished cases
    from other jurisdictions that imposed third-party liability on physicians in
    the context of failing to warn about communicable diseases. Indeed, aside
    from one brief footnote, the dissent, which quotes heavily from Jarmie,
    barely acknowledges that the present case raises a fundamentally different
    question—the third-party liability of a medical professional with respect to
    the misreporting of a sexually transmitted disease—than that at issue in
    Jarmie or any of our previous cases.
    As we explain more fully hereinafter, it is beyond cavil that both the
    law and the medical profession impose broader and different duties on
    physicians, duties that extend beyond the confines of the physician-patient
    relationship, with respect to the diagnosis of STDs and other infectious
    diseases. Of course, it is not unreasonable to take the position, as the dissent
    has, that, for reasons of public policy, we never should impose on physicians
    any duties beyond those established by the legislature. We think it would
    be a mistake, however, for this court to simply conclude that Jarmie disposes
    of the issue presented in this case without carefully evaluating the fundamen-
    tally distinct considerations that characterize the context of communica-
    ble diseases.
    11
    We recognize that there could be cases in which a dispute arises over
    whether the plaintiff is in fact the individual who was identifiable as a
    potential victim prior to the occurrence of negligence—if, for example, the
    defendant had argued that the plaintiff was not in fact the exclusive girlfriend
    of whom he was made aware when Smith sought STD testing. Because the
    defendant has not made that argument in the present case, for present
    purposes, the identity of the plaintiff as the identifiable victim is not in
    question. If it were, the question of identity would, of course, be a question
    of fact for the fact finder.
    12
    In Jarmie, we also relied on the fact that the defendant physician had
    not undertaken any affirmative action that placed the plaintiff at risk. Jarmie
    v. 
    Troncale, supra
    , 
    306 Conn. 624
    . In the present case, however, the plaintiff
    has alleged that the defendant affirmatively informed Smith that he was
    free of STDs, knowing that she might become intimate with Smith in reliance
    on that information.
    13
    We are not persuaded by the efforts of the dissent to distinguish Squeo.
    The dissent contends that Squeo is different because the claim in that case
    sounded in medical malpractice rather than ordinary negligence. See foot-
    note 2 of the dissenting opinion. This argument proves too much.
    The entire dissent is predicated on the concern that any recognition that
    physicians have duties to third parties will compromise the sanctity of
    the physician-patient relationship, jeopardize the confidentiality of patient
    records, promote unnecessary defensive medicine, and bring about higher
    insurance rates and health care costs, driving doctors out of practice and
    adversely affecting patient care. As we have explained, however; see part
    I B of this opinion; medical malpractice claims are those that go to the core
    of the physician-patient relationship: physicians are sued in their capacities
    as medical professionals, on the basis of the specialized medical care of a
    patient, involving the exercise of medical judgment. If nonpatient third
    parties can have standing to prosecute claims of that sort, as Squeo says
    they can, then, a fortiori, allowing them to bring claims sounding in ordinary
    negligence need not intrude on the sanctity of the physician-patient relation-
    ship. And, if our decision in Squeo has not resulted in the parade of horribles
    that the dissent invokes (and which are, in essence, the very same horribles
    that the defendants and certain of the amici in Squeo invoked); see Squeo
    v. Norwalk Hospital 
    Assn., supra
    , 
    316 Conn. 575
    –77; then we can have
    some reassurance that the alarmist warnings in the present case will be no
    more prescient.
    14
    One sister state court also has recognized a third-party duty to the
    spouse of a hospital employee who was not informed that he had been
    exposed to the human immunodeficiency virus (HIV), an STD, in the line
    of work. See Vallery v. Southern Baptist Hospital, 
    630 So. 2d 861
    , 862,
    868–69 (La. App. 1993), cert. denied, 
    634 So. 2d 860
    (La. 1994). But see Doe
    v. Pharmacia & Upjohn Co., 
    388 Md. 407
    , 409–10, 
    879 A.2d 1088
    (2005)
    (company that cultivated and harvested HIV cultures for incorporation into
    test for HIV antibodies owed no duty of care to spouse of employee who
    tested positive for HIV following workplace exposure).
    15
    Most of the cases on which the dissent relies address unrelated ques-
    tions, such as whether a physician has a duty to third parties to properly
    advise a patient as to his or her fertility status or potential to infect caregivers.
    See, e.g., Dehn v. Edgecombe, 
    384 Md. 606
    , 616, 
    865 A.2d 603
    (2005); Candela-
    rio v. Teperman, 
    15 A.D. 3d
    204, 204–205, 
    789 N.Y.S.2d 133
    (2005). The
    dissent also relies on Hawkins, which, as we have explained, is wholly
    consistent with the rule that we announce today. Indeed, the court in
    Hawkins concluded that a physician’s duty to accurately report the results
    of an STD test does run to identified third parties whose existence is known
    to the physician and who will foreseeably be infected as a result of the
    inaccurate report, precisely because the duty is intended in part for the
    benefit of those parties. See Hawkins v. 
    Pizarro, supra
    , 
    713 So. 2d 1037
    –38.

    18
    We emphasize that our recognition of a third-party duty in the present
    case is grounded in the unique characteristics of STDs in general and herpes
    in particular. Specifically, one—if not the primary—reason that patients
    seek to be tested for diseases such as herpes is to be able to represent to
    a potential sexual partner that they are disease free. Accordingly, the dis-
    sent’s fear that physicians will be liable to third parties for the improper
    diagnosis of conditions such as chicken pox, influenza, or the measles is
    unfounded. See footnote 9 of the dissenting opinion.
    19
    The dissent’s position appears to be that, if the defendant’s duty to the
    plaintiff is no more than the duty he owes to Smith to accurately report the
    test results, then holding the defendant liable to the plaintiff as well as
    Smith ‘‘would not reduce the potential for harm because health care provid-
    ers would be required to do no more than they already must do to fulfill
    their duty to patients.’’ (Internal quotation marks omitted.) Setting aside the
    fact that increasing a physician’s potential liability will presumably increase
    his or her incentive to avoid negligent errors of the type alleged, the present
    case is readily distinguishable from Jarmie, from which the dissent draws
    the quoted language. In the present case, unlike in Jarmie, which involved
    an automobile accident caused by the defendant physician’s patient, Smith
    himself is unlikely to have any cause of action against the defendant, insofar
    as there is no indication that he suffered legally cognizable damages. Accord-
    ingly, the defendant will face potential liability only to an identifiable third-
    party victim such as the plaintiff.
    20
    We note that ‘‘[m]any people in Connecticut are currently without health

    In order to prevent the spread of genital herpes, the CDC recommends
    that individuals take exactly the precautions taken by the plaintiff in the
    present case: ‘‘The surest way to avoid transmission of STDs, including
    genital herpes, is to abstain from sexual contact, or to be in a long-term
    mutually monogamous relationship with a partner who has been tested
    for STDs and is known to be uninfected.’’ (Emphasis added.) Centers for
    Disease Control and Prevention, Genital Herpes—CDC Fact Sheet (Detailed
    Version), available at https://www.cdc.gov/std/herpes/stdfact-herpes-
    detailed.htm (last visited July 5, 2019). The Department of Public Health
    also has recognized that encouraging sexually active individuals to seek
    regular STD testing is a high public health priority. See Connecticut Depart-
    ment of Public Health, Press Release, Department of Public Health Urges
    Residents To Be Tested for Sexually Transmitted Diseases (April 28, 2010),

    We disagree with the dissent that the legally relevant question is whether
    ‘‘a person harmed in the manner that this plaintiff was harmed would expect
    to be compensated by the physician . . . .’’ Clearly, the plaintiff expected
    there was some reasonable possibility that the defendant would be held
    accountable, or she would not have brought the present action. Equally
    clearly, she could not have had a high degree of confidence in a favorable
    result, as no Connecticut court had previously recognized such a duty.
    When the issue is, as a question of first impression, whether a previously
    unrecognized common-law duty should be recognized, it makes little sense
    (and is circular) for the result to hinge on whether a layperson accurately
    would predict that an appellate court would rule in her favor. The salient
    question in this case, rather, is whether a person in the plaintiff’s position
    reasonably would expect that a physician would adopt an STD test result
    reporting protocol with an eye toward the potentially serious harm that
    could befall a patient’s exclusive sexual partner if a negative result should
    be erroneously reported.
    22
    It may well be that the steady march of technology already has rendered
    purely academic the trial court’s concerns, as many patients now are able
    to view their test results directly through online electronic portals. See
    Office of the National Coordinator for Health Information Technology, ONC
    Data Brief No. 40 (April, 2018) pp. 1, 6, available at https://www.healthit.gov/
    sites/default/files/page/2018-04/HINTS-2017-Consumer-Data-Brief-april-
    2018.pdf (last visited July 5, 2019) (stating that, as of 2017, 52 percent of
    individuals were offered online access to their medical records, and that
    lab results were most frequently accessed information).
    The dissent speculates that recognizing a third-party duty under these
    circumstances will lead physicians such as the defendant to engage in costly
    defensive medicine, which could raise the cost of health care. The dissent
    does not contend, however, that recognizing such a duty will lead to the
    unnecessary use of expensive medical tests or other modalities typically
    associated with defensive medicine. Rather, the defensive medicine that a
    physician may embrace under these circumstances is the avoidance of asking
    a patient to identify his or her sexual partner or asking whether he or she
    is seeking STD testing for the purpose of informing future sexual partners
    of the results.
    We think that there is little realistic risk that physicians will alter their
    standards of care when errors of the sort alleged can be so easily and
    economically avoided by adopting simple quality control measures and exer-
    cising reasonable diligence. In any event, we fail to understand the harm
    that would result if a physician did not go out of his or her way to specifically
    identify a patient’s sexual partner.
    23
    We note that herpes may be transmitted by forms of intimate contact
    other than intercourse. See, e.g., 1 Harrison’s Principles of Internal Medicine
    (A. Fauci et al. eds., 14th Ed. 1998) p. 1085.
    24
    The dissent posits that our decision could have a significant impact on
    the health care system because more than 15,000 new STDs are diagnosed
    in Connecticut each year and, if we assume that each newly infected individ-
    ual was involved in an exclusive sexual relationship, then their more than
    15,000 partners all represent potential plaintiffs. This argument falters on
    many levels.
    Not surprisingly, having multiple and/or anonymous sexual partners is
    among the primary risk factors for contracting STDs. Centers for Disease
    Control and Prevention, STDs and HIV—CDC Fact Sheet (Detailed Version),
    available at https://www.cdc.gov/std/hiv/stdfact-std-hiv-detailed.htm (last
    visited July 5, 2019); see also L. Finer et al., ‘‘Sexual Partnership Patterns
    as a Behavioral Risk Factor for Sexually Transmitted Diseases,’’ 31 Fam.
    Plan. Persp. 228, 228–30 (1999). By contrast, if an individual is engaged in
    a truly and mutually monogamous relationship, then he or she is unlikely
    to contract an STD other than from his or her partner (who would not, in
    that scenario, be a potential plaintiff in a case such as this). Accordingly,
    the dissent’s assumption that each of the more than 15,000 individuals who
    contracted an STD in Connecticut in 2015 was involved in an exclusive
    sexual relationship seems highly implausible. Nor is there any reason to
    believe that a significant percentage of STD test results are inaccurately
    reported to the patient.
    Moreover, we note that, of the more than 15,000 new cases of selected
    STDs to which the dissent refers, the vast majority of them consist of
    chlamydia and, to a lesser extent, gonorrhea; see Connecticut Department
    of Public Health, STD Statistics in Connecticut, available at http://
    www.ct.gov/dph/cwp/view.asp?a=3136&q=388500 (last visited July 5, 2019);
    diseases that, unlike herpes, are readily treatable with antibiotics. See, e.g.,
    E. Moore, supra, pp. 77, 107–109. Accordingly, even for the fraction of new
    STD cases that might involve an identifiable victim, in a newly exclusive
    relationship, who would become infected as a result of an erroneous test
    report, the vast majority would suffer minimal damages and would be
    unlikely to go to the trouble of bringing a legal action.
    In sum, there is no reasonable basis for concluding that the present case
    is anything other than a singularity, let alone a harbinger of thousands of
    future legal actions. For example, there is no indication that other jurisdic-
    tions that have allowed such actions to proceed have experienced a spike
    in medical malpractice rates, and we are aware of no evidence to support
    the dissent’s warning that such an increase is ‘‘very likely’’ in this state.
    25
    Both parties have represented that Smith executed authorizations
    allowing the plaintiff to obtain and use his medical records for purposes of
    this action.
    26
    Moreover, as in all cases, trial courts are free to take reasonable mea-
    sures in mitigation of any such problems.
    27
    Lest there be any confusion, we emphasize that the existence of a third-
    party duty with respect to the accurate reporting of STD test results does
    not hinge on whether a patient and a victim remain romantically involved
    or whether the patient agrees to cooperate in the victim’s legal action. Our
    point is simply that, as in any legal action, the fact that a particular claim
    may be difficult to prove from an evidentiary standpoint does not imply
    that the claim itself is not legally cognizable.
