Upon commitment the patient shall be confined in the Northwest Georgia Regional Hospital or such other hospital as may be approved by the department for the care of tubercular patients for a period not to exceed six months unless, before the expiration of such six-month period, the designated responsible physician of the tuberculosis inpatient unit determines that the following conditions no longer exist:

(1) The patient has contagious tuberculosis; or

(2) The patient has active tuberculosis and there is a substantial likelihood of future noncompliance with a proposed treatment plan which will predictably lead to the development of infectious drug-resistant tuberculosis. The likelihood of noncompliance must be based upon a history of a prior commitment followed by noncompliance with outpatient treatment; provided, however, that short emergency leaves in the event of death or critical illness in the family or short therapeutic leaves may be granted under conditions which would not adversely affect the public health and in accordance with rules and regulations established by the department.
