It shall be the duty of a physician attending a patient for tuberculosis to take all proper precautions and to give proper instructions to provide for the safety of all individuals occupying the same house or apartment.
(h) Removal of Patient, Etc. Whenever a person having tuberculosis is unable for financial reasons, or from any other cause, to comply with the rules of the Director of Public Health providing for the precautions to be observed to prevent the spread of infection, or when such person willfully refuses to comply with said rules and in all cases where children are unavoidably exposed to infection, the Director of Public Health may, on presentation to it of proof that such person is a sufferer from tuberculosis, order his immediate removal to a hospital or other institution for the care of sufferers from tuberculosis.

Upon the receipt of this statement and report, the Director of Public Health shall examine the same and satisfy himself that the attending physician has taken all necessary and desirable precautions to insure the safety of all persons living in the apartment or premises occupied by the person having tuberculosis. If the precautions taken or instructions given by the attending physician are, in the opinion of the Director of Public Health, not such as will remove all reasonable danger or probability of danger to the persons occupying the same house or apartment or premises, the Director of Public Health shall return to the attending physician the report with a letter specifying the additional precautions or instructions which the Director of Public Health shall require him to make or give; and the said attending physician shall immediately take the additional precautions and give the additional instructions specified and shall record and return the same on the original report to the Director of Public Health. It shall be the duty of the Director of Public Health to transmit to every person reporting any case of tuberculosis, or if there be no attending physician, to the person reported as suffering from this disease, a circular of information which shall inform the consumptive of the precautions necessary to avoid transmitting the disease to others.
