In this admittedly tragic case, we are asked to decide, under Pennsylvania law, the nature and extent of a physician’s duty to third persons when the physician undertakes the treatment and care of a patient with a contagious disease. Instantly, the trial court determined as a matter of law that a doctor has no duty to warn a patient with a highly contagious but ubiquitous viral infection that the patient should avoid contact with pregnant women whose unborn infants may be at risk of death or debilitating birth defects if they are exposed to the virus. The trial court granted appellees Ches-Penn Health Services and Kevin Browngoehl, M.D.’s motion for summary judgment basing its decision on this court’s opinion in
Troxel v. A.I. duPont Institute,
Summary judgment may only be granted “if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that
*75
there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” Pa.R.Civ.P.Rule 1035(b). The trial court must view the evidence, and all reasonable inferences to be drawn therefrom, in the light most favorable to the non-moving party, with any doubt resolved against the moving party. The trial court will be overturned only if there has been an error of law or a clear abuse of discretion.
First Wisconsin Trust Co. v. Strausser,
The facts and procedural history, taken from Troxel I, are set forth below:
On October 30, 1987, Mary Siple, a non-party, gave birth to a female child, Ashley [Smith]. Because Ashley was born with microcephaly [footnote omitted] and a pes cavus deformity of the leg, [footnote omitted] she was taken for treatment to Ches-Penn Health Services, Inc., a Pennsylvania medical services center, where she was examined by Dr. Kevin Browngoehl, a Pennsylvania physician. Dr. Browngoehl suspected that Ashley was suffering from cytomegalovirus (CMV) [Footnote] and referred her to [the A.I.] duPont [Institute] for additional tests. At duPont, Ashley was seen by Dr. Borkowski, a Delaware neurologist. The tests conducted at duPont, under Dr. Borkowskfs supervision, confirmed a diagnosis of CMV. In the meantime, Ches-Penn discovered that Ashley’s mother, Mary Siple, was also suffering from CMV.
Grace Troxel was a long time friend of Mary Siple, and, in November, 1987, she became pregnant. During her pregnancy she frequently visited Mary Siple and often assisted in feeding and bathing Ashley and in changing her diapers. In May, 1988, Mary Siple learned, allegedly for the first time, that CMV was contagious and posed a special danger to pregnant women. By this time, Grace Troxel had entered the third trimester of her pregnancy and was already infected with CMV. On August 19,1988, she gave birth to a *76 son, Trevor. Unfortunately, Trevor had acquired CMV from his mother in útero and died from the disease on November 17,1988.
Grace and Daniel Troxel filed wrongful death and survival actions on behalf of their deceased son and also for the infection of Grace Troxel with CMV. They named as defendants duPont and Ches-Penn, which subsequently joined Dr. Browngoehl as an additional defendant. The essence of plaintiffs’ claim was that defendants had failed to inform Mary Siple of the contagious nature of CMV and of the risk to pregnant women who might come into contact with her infant. Dr. Browngoehl filed a cross-claim against the remaining defendants pursuant to Pa.R.C.P. 2252(d).
Troxel I, supra
at 467,
The issue before the
Troxel I
court was whether the trial court properly entered summary judgment in favor of the Delaware defendant, duPont. In order to make that determination, the
Troxel I
court had to decide whether to apply the substantive law of Delaware or Pennsylvania. Finding that the substantive law of Delaware applied, the
Troxel I
court then determined that, under Delaware law, no cause of action existed because no duty existed on the part of the medical providers toward third persons, absent a special relationship between the doctor and the patient or the doctor and the third person.
Id.
at 471-72,
The Troxel I court then analyzed whether § 324A of the Restatement conferred a duty upon physicians toward third parties under Delaware law. Section 324A provides:
§ 324A. Liability to Third Person for Negligent Performance of Undertaking
One who undertakes, gratuitously or for consideration, to render services to another which he should recognize as necessary for the protection of a third person or his things, 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
(b) he has undertaken to perform a duty owed by the other to the third person, or
(c) the harm is suffered because of reliance of the other or the third person upon the undertaking.
Troxel I, supra
at 473-74,
*78
The
Troxel I
court then noted that, in contrast to Delaware, the Pennsylvania Supreme Court had found that a physician owed a duty to third parties who were not his patients under § 324A in
DiMarco v. Lynch Homes
—Chester
County, Inc.,
In sustaining defendants’ preliminary objections, the trial court relied upon the physician’s lack of control over the sexual conduct of his patients and the public policy against non-marital sex.
DiMarco I, supra
at 465-66,
*79
On appeal, however, we reversed the trial court. While first recognizing the general rule that the duty of a physician arises from the physician/patient relationship,
citing Craddock v. Gross,
Justice Montemuro opined as follows:
In the case at bar, we find that the appellant has stated a cause of action, pursuant to Section 324A, even though there was no physician-patient relationship between the appellant and [the phlebotomist’s] physicians. In Cantwell v. Allegheny County,506 Pa. 35 ,483 A.2d 1350 (1984), our Supreme Court recognized that the essential provisions of Section 324A ‘have been the law of Pennsylvania for many years.’ Id. at 40,483 A.2d at 1353 . The present case is distinguishable from Ervin and Craddock, supra, which also lacked a physician-patient relationship between the plaintiff and the defendant, for a number of significant reasons. First, a physician-patient relationship did exist in the present case between [the phlebotomist] and her physicians. [The phlebotomist] visited her physicians for the purpose of receiving professional treatment and medical advice when she knew that she may have been exposed to hepatitis. Second, this case involves a communicable disease. It hardly needs to be said that the prevention and control of communicable diseases is a momentous task which is of the utmost importance to the health and welfare of our citizens....
Although there is a dearth of case law addressing medical malpractice in relation to communicable disease, several *80 other jurisdictions have considered cases similar to the case at bar. Although none of these cases rely on Section 324A of the Restatement (Second) of Torts, we find their reasoning and underlying public policy considerations persuasive____
DiMarco I, supra
at 469-70,
On grant of allocatur, the supreme court affirmed this court’s decision in DiMarco I, holding:
If a third person is in that class of persons whose health is likely to be threatened by the patient, and if erroneous advice is given to that patient to the ultimate detriment of the third person, the third person has a cause of action against the physician, because the physician should recognize that the services rendered to the patient are necessary for the protection of the third person.
DiMarco II, supra
at 562,
In interpreting this holding of the supreme court, the
Troxel I
court appears to have construed the language narrowly in stating that
DiMarco II
stood only for the proposition that “a physician could be held liable to a third person for incorrect advice given a patient regarding a communicable disease (hepatitis) when the physician knew of the patient’s sexual partner and should have foreseen that the third party
*81
would rely upon the physician’s advice to the patient.”
Troxel I, supra
at 471-72,
While the
Troxel I
court opted to limit the supreme court’s holding in
DiMarco II,
we are not deterred in our analysis because
Troxel
I’s interpretation of
DiMarco II
is not the law of the case instantly. The sole question before the
Troxel I
court was whether the trial court properly entered summary judgment in favor of the
Delaware
defendant,
A.I. duPont Institute.
Once the
Troxel I
court determined that Delaware law applied, its interpretation of Pennsylvania law became merely advisory. As a result, contrary to the trial court’s reliance,
Troxel
I’s interpretation of
DiMarco II
is not the law of this case.
See Banker v. Valley Forge Insurance Co.,
Having found that Troxel I does not control the outcome of the instant case, we must next decide whether, under Pennsylvania law, the Troxels have a cause of action on behalf of their deceased son against Ashley Smith’s Pennsylvania medical providers. The essence of this issue is whether Dr. Browngoehl owed a duty to Trevor Troxel. As our supreme court stated:
‘In determining the existence of a duty of care, it must be remembered that the concept of duty amounts to no more than “the sum total of those considerations of policy which led the law to say that the particular plaintiff is entitled to protection” from the harm suffered. To give it any greater mystique would unduly hamper our system of jurisprudence in adjusting to the changing times. The late Dean Prosser expressed this view as follows:
These are shifting sands, and no fit foundation____ Duty is only a word with which we state our conclusion that there is or is not to be liability; it necessarily begs the essential question.... In the decision whether or not there is a duty, many factors interplay: The hand of history, our ideas of morals and justice, the convenience of administration of the rule, and our social ideas as to where the loss should fall. In the end the court will decide whether there is a duty on the basis of the mores of the community, “always keeping in mind the fact that we endeavor to make a rule in each case that will be practical and in keeping with the general understanding of mankind.” ’
Gardner by Gardner v. Consolidated Rail Corp.,
*83 Initially, appellants concede that the reliance prong of 324A(e) upon which the DiMarco courts relied is not available to them instantly to establish a duty owed to Trevor Troxel. Dr. Browngoehl gave no information to Mary Siple about the contagious nature and risk implications of Ashley’s disease. However, appellants contend that this fact should not preclude a finding of liability. Rather, they argue that the duty in DiMarco II was imposed on the basis of the foreseeability of the harm and not on the basis of reliance. 3
Appellants cite the following language from DiMarco II in support:
When a physician treats a patient who has been exposed to or who has contracted a communicable and/or contagious disease, it is imperative that the physician give his or her patient the proper advice about preventing the spread of the disease. Communicable diseases 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.’
Such precautions are taken not to protect the health of the patient, whose well-being has already been compromised, rather such precautions are taken to safeguard the *84 health of others. Thus, the duty of a physician in such circumstances extends to those “within the foreseeable orbit of risk of harm.’
DiMarco II, supra
at 560-62,
We agree with appellants’ analysis of
DiMarco II
and decide that reliance was not the sole basis upon which the duty was imposed. Rather, the court recognized a duty owed by the physician based upon the important role of the medical community in preventing the spread of communicable diseases, a duty that extends to all those within the foreseeable orbit of risk of harm. Our interpretation is supported by subsequent decisions of this court which distinguished the
DiMarco
decisions on the basis of lack of foreseeable risk. For instance, in
Crosby by Crosby v. Sultz,
Even if Dr. Sultz did have a duty to disclose Jackson’s name to the Department of Transportation, we can find no logical connection between that obligation and a duty of care to the Crosbys. The Crosbys were not foreseeable victims of Dr. Suite’s actions or inactions____ To discount the important element of foreseeability here is effectively to overrule well-established and precedential tort law, as well as to extend liability limitlessly to treating physicians vis-avis third party victims.
We note here that diabetes is not a communicable disease, such as hepatitis. See DiMarco, supra. Thus, we refrain from likening the instant circumstances to those in DiMarco.
Crosby by Crosby,
Our next task, then, is to determine whether appellants have alleged sufficient facts to establish that appellees should have foreseen that their treatment of Ashley Smith was necessary for the protection of third persons such as Trevor Troxel.
Waddell, supra
at 472-74,
The medical community is well aware of the risks CMV poses to
in útero
infants. While it is true that Dr. Browngoehl and his associates had no way of knowing the identity of particular pregnant women whose infants would be at risk from exposure to Ashley, and therefore could not possibly be expected to warn the pregnant women, nevertheless, these doctors knew, or should have known, that a class of persons very likely to come into contact with a young mother and her new baby were at risk, and that the risk was deadly. Despite
*86
this awareness, neither duPont, Dr. Browngoehl, nor anyone else at Ches-Penn advised Mary Siple of the contagious nature of CMV, or of the fact that she and Ashley should avoid close contact with pregnant women. (Trial court opinion, 2/24/95 at 3.) As a result, Mary Siple continued to associate with her close friend, Grace Troxel, who had become pregnant in November of 1987 and who would frequently feed, change, hold, and kiss Ashley during visits with Mary and Ashley.
(Id.)
Based upon the analysis articulated by the
DiMarco II
court as applied to the facts alleged by appellants, it is clear that Grace Troxel’s unborn son Trevor was within that “class of persons whose health [was] likely to be threatened by the patient----” and thus he was within the “ ‘foreseeable orbit of risk of harm[.]’ ”
DiMarco II, supra
at 562,
As already noted, this court, in finding a duty on the part of the physicians to DiMarco in
DiMarco I,
based that duty in part on § 324A(c) of the Restatement, and in part upon its review of the case law from other jurisdictions. Numerous courts throughout the country have addressed the issue of whether a doctor or other health care provider is liable to a third party who contracts a contagious disease from the doctor’s patient.
See
Tracy A. Bateman, Annotation,
Liability of Doctor or Other Health Practitioner to Third, Party Contracting Contagious Disease from Doctor’s Patient,
In Wojcik, Joseph Wojcik and his wife Caroline sued Mr. Wojcik’s employer for failing to inform him that the results of his chest X-ray, taken during the course of a physical examination at work, indicated he had tuberculosis. The physician who read the X-ray was apparently an agent of the employer, whose practice it was to inform employees of any physical problems. Because Joseph Wojcik was not informed he had a contagious disease, his wife failed to take steps to protect herself from contracting the disease. In holding that Caroline Wojcik had stated a claim, the Wojcik court opined:
*87 ‘In 41 AmJur., Physicians and Surgeons, § 101, p. 216, it is stated: “One who by reason of his professional relations is placed in a position where it becomes his duty to exercise ordinary care to protect others from injury or danger is liable in damages to those injured by reason of his failure to do so.” The policy of the law in general is stated in 70 C.J.S. Physicians and Surgeons § 48, p. 970, as follows:
It is the duty of a physician who is attending a patient afflicted with a contagious or infectious disease to exercise care in advising and warning members of the family and others who are liable to exposure of the existence and nature of the danger from the disease, to avoid doing any act which would tend to spread the infection, and to take all necessary precautionary measures to prevent its spread to other patients attended. A physician who fails to give such warning is negligent....’
DiMarco I, supra
at 471,
*88 As a result of the foregoing, we have no doubt that a fair reading of the DiMarco decisions extends the duty of a physician to third persons in instances where the physician undertakes the treatment of a patient with a communicable or contagious disease. This duty encompasses a duty to correctly inform the patient about the contagious nature of the disease in order to prevent its spread to those who are within the foreseeable orbit of risk of harm.
Appellees argue that even if DiMarco has imposed such a duty, it does not encompass a ubiquitous disease such as CMV. Framing this question within the procedural posture of this case, we need only decide whether the trial court erred as a matter of law when it found that CMV was not a contagious disease within the meaning of DiMarco. If CMV is a disease contemplated by DiMarco, then its ubiquitous nature is better addressed in the context of whether Dr. Browngoehl’s conduct fell below the standard of care of a physician whose patient has a contagious disease.
Initially, it is conceded by both appellants and appellees that CMV is a contagious disease; that it exists in the general population; that while it is generally harmless and often may go unnoticed in most individuals, it may have severe consequences for certain at-risk groups, such as those whose immune systems have already been compromised, pregnant women and newborns. The risks are not obscure but rather are well recognized in the literature of the medical community. The American Academy of Pediatrics Committee on Infectious Diseases, while advocating no special screening or quarantining of children with CMV in daycare centers and schools, does clearly recognize that there is a risk to pregnant women who care for CMV children and that they should be urged to practice good hygiene. (Plaintiffs’ Answer to Motion for Summary Judgment of Defendant, Ches-Penn Health Services, Inc. and Additional Defendant Kevin Browngoehl, M.D., Exhibit H, Report of the Committee on Infectious Diseases at 141-12 (20th ed., 1986).) Additionally, appellants have cited to numerous procedures and regulations governing hospitals which recognize the risk factors and preventive measures *89 connected with CMV. (Appellants’ brief at 16, citing, inter alia, the Centers for Disease Control (CDC) Guidelines.) We agree with appellees that these regulations do not impose a duty on physicians; nevertheless, they clearly suggest common knowledge in the medical community of the nature of CMV and its risks to pregnant women and their unborn children.
While we recognize that the communicable disease in
Di-Marco,
hepatitis-B, is a so-called “reportable” disease, while CMV is not, we agree with appellants that, for our purposes, this is a distinction without a difference. Both this court and our supreme court referred to the reporting requirements only
to
emphasize that a physician’s duty can extend to the protection of third persons. As the
DiMarco II
court stated, “Clearly, such [reporting] measures are mandated by law specifically to protect
third persons
who will come into contact with those who have been exposed to or have contracted a communicable disease.”
DiMarco II, supra
at 563,
Appellees argue that imposing a duty on a physician in this case would render physicians liable for the spread of any infectious disease, even the flu or the common cold. We disagree. The reason the court imposed a duty in DiMarco was to ensure that information regarding the infectious nature of communicable diseases be made available for the protection of others besides the patient. In the case of viruses such as the flu or the cold, such information is common knowledge. In contrast, where certain risks regarding the spread of certain diseases may only be known within the medical profession, it is essential that correct information be disseminated by the physician. For example, in the case of AIDS 5 or hepatitis, which appellees must concede are covered by the DiMarco duty, a physician has a duty to inform the patient how to avoid the spread of the disease by avoiding specific at-risk conduct, even though the general population may not be otherwise at risk. The same can be said of the communicable nature of CMV.
*90 We recognize that DiMarco involved a misfeasance by the treating physicians, who gave the phlebotomist incorrect information, whereas instantly, we are confronted with a physician who gave Mary Siple no information. We do not believe, however, that the public policy of this state would be well served by encouraging physicians to tell their patients nothing about their communicable diseases in order to avoid potential liability. The standard of care for a physician who is treating a patient with a communicable disease is to inform the patient about the nature of the disease and its treatment, to treat the patient, and to inform the patient how to prevent the spread of the disease to others. (R.R. at 193a, 195a, 226a, 257a.) To find that a physician has a duty to impart accurate information, but no duty to impart any information, would be to turn logic on its head.
The jury in the instant case might well decide that Dr. Browngoehl acted appropriately when he said nothing about the contagious nature of CMV. Conversely, a jury might decide that Dr. Browngoehl’s duty required a simple warning to Mary Siple that pregnant women should not be involved in Ashley’s caregiving, or that they should take extra precautions if they were. This is not an onerous burden. Yet it is one with a potentially enormous benefit.
Based upon all of the foregoing, we find that the duty enunciated by DiMarco II does apply to this case. We also find that the trial court erred as a matter of law in deciding that CMV is not the type of disease encompassed by this duty. Whether Dr. Browngoehl acted appropriately under the circumstances is a question better left to the jury.
As a result, we reverse the order of the trial court granting appellees’ motion for summary judgment and remand for proceedings consistent with this opinion. Jurisdiction is relinquished.
[Footnote] CMV is a ubiquitous disease which is a member of the heipetoviruses group that causes an enlargement of the cells of various organs. In infants, it may result in jaundice, enlargement of the spleen and liver, thrombocytopenic purpura, and possibly mental retardation. The disease is spread by prolonged intimate contact with infected body fluids. Ausman and Snyder, 7 Medical Library — Lawyers Edition § 17:29 (1991).
Notes
. We note that the superior court opinion indicates the phlebotomist was told to refrain from sexual relations for six weeks, and also indicates that the doctors knew both the phlebotomist and DiMarco personally and “ ‘were aware or had reason to know that [DiMarco] and [the phlebotomist] were intimate.’ ”
DiMarco v. Lynch
Homes—
Chester County, Inc.,
. As to the validity of this interpretation, see footnote 4, infra.
. The amicus brief filed on behalf of the Pennsylvania Trial Lawyers Association argues that the facts of this case fall within the meaning of 324A(c). Mrs. Troxel relied on the lack of information given to Maty Siple. This reliance is evidenced by Mrs. Troxel immediately altering her behavior once informed of the contagious nature of the disease. We believe that the point is well taken, and in the context of malpractice as between doctor/patient, a failure to warn, to diagnose, or to disclose is considered misfeasance rather than nonfeasance. However, we can find no authority to support nonfeasance as a basis for liability under 324A(c). As set out in § 314 of the Restatement, absent special circumstances, "The fact that the actor realizes or should realize that action on his part is necessary for another’s aid or protection does not of itself impose upon him a duty to take such action.” Restatement (Second) of Torts, § 314 (1965).
