This action was brought by appellants against the appellees to recover damages. The appellants alleged in substance that the appellees were regularly licensed and practicing physicians associated together as partners and doing a general practice of medicine at Newark and vicinity in Independence County, Arkansas: that appellants were man and wife, having a family of six minor children, and two adult married sons, who lived in their own homes apart from the appellants; that one of these sons, Curtis Davis, on June 15, 1919, was stricken with typhoid fever; that their son Lawson nursed him and was also, on July 15, 1919, stricken .with typhoid fever; that the appellees were the attending physicians, and as such they negligently and wilfully *389failed to notify the county health officer that typhoid fever was at the residence of Curtis and Lawson Davis; that they failed to post notices in front and at the rear of the residences of Curtis and Lawson Davis and failed to instruct the patients and their attendants, appellants, and other nurses in all the necessary sanitary measures for them to observe in order to prevent the spread of the disease; that they failed to vaccinate the appellants, and other nurses, attendants, and all other persons who had been exposed to the disease; that they failed to isolate the patients in a room to themselves and to screen the room from flies; that they failed to have buried or disinfected the secretions and excretions from the body of the patients and failed to instruct the attendants to carry out and execute all the rules and regulations of the board of health pertaining to and necessary to prevent the spread of typhoid germs, which it was their duty to do, and ignored all precautions and sanitary measures'necessary to prevent the spread of the disease, which was contagious; that appellees advised the appellants to move the patients from their own homes to the homes of appellants, which appellants did; that the appellees failed to notify the appellants that typhoid fever was a contagious disease and failed to take the precautions above set forth to prevent the spread of the disease; that as a result of appellees’ negligence as above set forth, appellant, N. A. Davis, on the 12th day of October, 1919, became infected with typhoid germs, from which she suffered great physical pain and mental anguish resulting in permanent injury to her health, all of which, together with the sums she was compelled to expend for nursing, medicine and doctors’ bills, damaged her in the sum of $3,000; that the minor sons, Paul and Dallas Davis, as a result of the negligence above set forth, also contracted typhoid fever on the 15th day of October, 1919, to the appellants’ damage, items of which were specified, in the sum of $3,000; that Walker Davis, another minor son, on October 15, 1919, from the same cause, contracted the disease and thereafter died, to ap*390pellants ’ damage, which they specified, in the sum of $3,000; that appellant J. L. Davis, also by reason of the negligence of appellees as above set forth, contracted the disease, from which he suffered physical pain and mental anguish, which rendered him unable to perform his regular work, impaired his health permanently, decreased his earning power and compelled him to incur debts for medicine, nursing and doctors’ bills, all to his damage in the sum of $3,000. The complaint concludes with a prayer for judgment in the sum of $3,000. The appellees entered a general demurrer to the complaint. The court entered judgment sustaining the demurrer and dismissing the complaint, and for costs in favor of the appellees, from which judgment is this appeal.
1. Typhoid fever is an infectious febrile disease caused by a micro-organism called bacillus typhosus, introduced into the system by the fingers, or with the food or drinking water. Osier’s Principles and Practice of Medicine, 1-5; Forcheimer’s Therapeusis of Internal Diseases, vol. 5, p. 203; (Webster’s Dictionary; New International Dictionary — Typhoid Fever). It is declared by the State Board of Public Health to be “contagious, infectious, and communicable.” Rules and Regulations of the State Board of Health, p. 5, § 11..
A' contagious disease is one communicable by contact with a patient suffering from it, or with some secretions or object touched by such a patient. (Webster “Contagious.”) “Fingers, food, water and flies are the chief means of propagation.” .Osier’s Principles and Practice of Medicine, 5.
Keeping in mind these definitions of. infectious and contagious diseases, and their means-of propagation, we have reached the conclusion that the allegations of the complaint do not state facts sufficient to show that any of the acts of negligence alleged were the proximate cause of the typhoid fever contracted by the appellants and their children. It is not alleged -in the complaint that typhoid fever is an infectious disease. While there is an allegation to the effect that the appellees “failed to have *391buried or disinfected the secretions and excretions from the bodies of the patients,” there is no allegation to the effect that such failure caused the typhoid germs to get into the food or water used by appellants and their children, or in any other manner to be introduced through the mouth into the intestines of the victims of the disease. Moreover, there is no duty imposed upon physicians by statute to personally bury, or disinfect, the secretions or excretions of their typhoid fever patients.
The State Board of Health requires that “no person in charge of a typhoid fever patient shall so dispose of the excreta or other infectious bodily secretions or excretions as to cause offense or danger to any person or persons.” R. & R. of State Board of Health, 1918, p. 16, § 89.
If it be conceded that this section makes it the duty of physicians to instruct those in immediate charge of a patient to dispose of the excretions and secretions in the above manner, still there are no allegations of fact which show that the failure to discharge that duty was the proximate cause of the communication of the disease to appellants and their children. In other words, it is not alleged that the failure of the physician to instruct the nurses or attendants in charge of the patient caused such nurses or attendants to dispose of the excretions and secretions, so that the water which appellants and their children drank, and the food they ate,, became infected thereby with the typhoid bacillus.
It is undoubtedly the duty of physicians who are attending patients afflicted with contagious or infectious diseases not to negligently do any act that would tend to spread the infection. It would likewise be their duty to exercise reasonable care to advise members of the family and others, who are liable to be exposed thereto, of the nature of the disease and the danger of exposure. The relation of a physician to his patient and the immediate family is one of the highest trust. On account of his scientific knowledge and his peculiar relation, an attending physician is, in a certain sense, in custody of a *392patient afflicted with infections or contagious disease. And he owes a duty to those who are ignorant of such disease, and who by reason of family ties, or otherwise, are liable to be brought in contact with the patient, to instruct and advise them as to the character of the disease.
It is a sound rule of law that one wlm by reason of his professional relation 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 who are injured by reason of his failure to exercise such care. Skillings v. Allen, 5 A. L. R., p. 922 and note. It was, therefore, the duty of the appellees, when called to attend the children of appellants, to notify the latter, other nurses and attendants, of the nature and character of the disease, to warn them of the danger of infection, and to instruct them as to the usual methods approved by the profession, of which they have knowledge, for the prevention and spread of the disease. This duty was incumbent upon the appellees, regardless of the rules and regulations of the State Board of Health on the subject. 30 Cyc. p. 1577; 21 R. C- L., § 33, p. 389. But it was not the duty of appellees as physicians to enforce the rules of the State Board of Health for the prevention of typhoid fever. That was the duty of local health officers. R. & R. of State Board of Health, p. 16, R. 90.
It is alleged in the complaint that “appellees negligently failed to instruct said patients, their attendants, the plaintiffs, and other nurses that the patients had typhoid fever, a contagious disease, or as to what were necessary sanitary precautions for them to observe and practice to prevent the spread of said disease.” There is no allegation of fact to show that the alleged negligence of the appellees in the respects named caused appellants’ children to contract the disease. The general allegations that “appellees encouraged people1 to come in contact with their patients,” and that grossly negligent acts of defendants conduced to infect plaintiffs and *393their families with typhoid fever germs,” are not sufficient. There is no allegation that if the warning and instructions had been given appellants could and would have heeded and obeyed them. Specific acts and facts showing how and why the alleged negligence of appellees was the proximate cause of the injury of which the appellants complain, were necessary to be stated. These can not be supplied by intendment.
2. One of the rules of the State Board of Health requires “every physician to report, as soon as possible, every case of communicable disease, declared notifiable, which occurs in his practice, to the local city and county health officer having jurisdiction.” Typhoid fever is such a disease. It is made a misdemeanor for any person to violate this rule. R. & R. State Board of Health 1918, p. 6, rule 12; Act 96, p. 360 of Acts 1913.
It is alleged that the appellees negligently failed to comply with this rule. But again there is no allegation of specific acts or facts showing that the failure of ap.pellees to perform this statutory duty was the proximate cause of the injury to appellants. There is no allegation that, if appellees had complied with this rule, appellants and their children would have escaped typhoid fever. Violation of the rule was evidence of negligence. Bain v. Fort Smith L. & T. Co., 116 Ark. 125; Pankey v. Little Rock Ry. & Elec. Co., 117 Ark. 337-44. But such violation was not actionable negligence creating civil liability unless it was the proximate cause of the injury to appellants. The necessary facts and acts to show this are not alleged.
3. Appellees were negligent in advising appellants to move their son, Lawson Davis, from his residence to appellants’ residence, and telling them that they could put him among the other children where he could see his little brothers and sisters. Skillings v. Allen, supra; Hewett v. Woman’s Hospital Aid Assn., 73 N. H. 556, 7 L. R. A. (N. S.) 496-99. Assuming this allegation to be true, which we must on demurrer, such instructions coming from attending physicians without warning of *394the danger of infection to the other children of the appellants, were acts of gross- negligence. Bnt here again specific acts and facts are not alleged which show how or why this advice and these instructions caused the injury to appellants. On the contrary, it is alleged that typhoid fever was a contagious disease, and that the appellants had nursed their son, Curtis Davis, before he was removed to the residence of the appellants; and other allegations show that appellants were in attendance upon him before the appellees were called to his ■bedside. Now, “the period of incubation for typhoid germs lasts from eight to fourteen days,, sometimes twenty-three.” Osler, P. & P. Med. 14. An allegation further shows that one of the appellants, N. A. Davis, was infected with typhoid germs on the 12th day of October, 1919, three days before any of the minor children of appellants became infected with the disease. According to this allegation, the minor children were affected on the 15th day of October, 1919. Therefore, according to the allegations of the complaint, the appellants may have contracted the disease before either of their adult sons were moved to the residence of appellants, and the minor children may have contracted the disease from their mother, rather than from their elder brother. For she had voluntarily exposed herself and had come down with the fever before the minor sons were attacked.
To fix civil liability, for so serious a delinquency as that set forth in the complaint, it was necessary to allege specific acts and facts showing that the injury to appellants was caused directly and approximately by such delinquency. Here the allegations show that appellants may have contracted the disease before appellees advised appellants to move their adult son, and the minor sons may have contracted the disease from their mother, rather than from their brother. Therefore, the source of infection of the minor children is not definitely traced to any act of negligence of appellees. The allegations on this vital subject are not sufficient to state a cause of action.
*3954. It is alleged that the appellees negligently failed to vaccinate the appellants, their minor children, attending nurses and other persons who had been exposed to the disease. The term “vaccinate” is here loosely used by the pleader for “ inoculate. ’ ’ In the first place, the appellees could not inoculate the appellants, or their minor children, without appellants’’ consent. It is not alleged that appellants requested appellees to “vaccinate” them or their children, or that appellants would have consented thereto if appellees had suggested it. In the second place, in the absence of a statute requiring it, whether inoculation shall be resorted to as a means for preventing the spread of contagious or infectious diseases is a matter addressed solely to the independent judgment and discretion of the attending physician. It can not be said that the efficacy of inoculation of a specific vaccine to prevent the spread of typhoid fever has been so thoroughly established 'by medical science as to make it the absolute duty of physicians to inoculate nurses, attendants and persons exposed during an epidemic of that disease.’
The medical authorities cited in the briefs of learned counsel for the respective parties to this litigation show that doctors themselves differ as to whether inoculation would furnish complete immunization against typhoid fever. Although the majority of eminent medical authorities now advocate inoculation as a preventive of typhoid fever, yet, until it has been demonstrated beyond doubt that inoculation affords complete immunization against the disease, it must be left to the judgment and discretion of the physician, under the circumstances of each particular case, to determine whether inoculation is necessary. Tyson’s Practice of Medicine (5 ed.), p. 126; 2 Forcheimer’s Practice of Medicine; Sajous’ Ency. of Medicine; Osier, P. & P. of Med. 41; 5 Forcheiiner’s Therapeusis of Internal Diseases, 201. Matters of this kind require scientific investigation and expert knowledge to determine. It can not be left to a jury to say whether *396the expert in the practice of his profession has pursued the proper course.
The judgment is correct, and it is therefore affirmed.
