(a) Upon receiving a duly signed report of a person who appears to be suffering from tuberculosis pursuant to sections 2100 and 2222 of the Public Health Law, the State or local health officer to whom such cases are reportable shall cause an examination to be made of the case if it has not been previously reported by a physician as a case of pulmonary tuberculosis and shall take such further measures as may be indicated as a result to such examination; if such a person has been reported to him previously by a physician as one suffering from pulmonary tuberculosis, the State or local health officer concerned shall ascertain promptly whether such physician is maintaining proper sanitary supervision.

(b) It shall be the duty of a physician in attendance on a person affected with active pulmonary tuberculosis to instruct such person or a responsible member of his family not to permit personal contact with non-household members or occupational contact with others until the patient is deemed to be non-infectious.
