Upon receiving a report of the existence of a case or suspected case of a communicable disease, or of a communicable disease contact or carrier, the Director shall make any investigation that he or she deems necessary for the purpose of determining the source of infection and of determining if the proper management and control measures are in effect.
In order to make an investigation under this section, the Director may enter upon and inspect any public or private property in the District.
Where the Director has probable cause to believe that sectors of a communicable disease or sources of a communicable disease have been identified, the Director shall cause to be instituted whatever preventive measures as the Director may deem necessary to eradicate immediately the vectors and sources of the communicable disease.
Any person having or suspected of having a communicable disease, or any person who is suspected of being a communicable disease contact or carrier, shall, when directed by the Director, submit to an examination for the purpose of determining the existence of a communicable disease.
A person suspected of having a communicable disease, or a person who is suspected of being a communicable disease contact or carrier, shall submit specimens or permit the obtaining of authentic specimens of body secretions, excretions, body fluids, and discharges for laboratory examinations, when required by the Director. These specimens shall be authenticated, when required by the Director.
The Director may authorize or order a placard to be posted on the premises occupied by any person affected with a communicable disease.
No placard authorized or ordered by the Director to be posted shall be mutilated, defaced, obliterated, concealed, or removed, except by authorization of the Director.
The Director shall issue a Removal and Detention Order and take whatever further proceedings may be required by sections 1 through 14 of the Act (D.C. Official Code §§ 7-131 through 7-144) (2001), whenever the Director has probable cause to believe that any person is affected with, or is a carrier of, a communicable disease, and whenever the Director has probable cause to believe that that person is likely to be dangerous to the life or health of any other person because of the following reasons:
Each infected person, contact, or carrier shall comply with the instructions given him or her by the physician or other person responsible for the control of a case of communicable disease.
