(1) Immediately after being notified of a case or an outbreak of a reportable disease, a local health officer must investigate and take whatever steps are necessary to prevent spread of the disease.

(2) If the local health officer finds that the nature of the disease and the circumstances of the case or outbreak warrant such action, the local health officer must:

(a) examine or ensure that a health care provider examines any infected person in order to verify the diagnosis;

(b) make an epidemiologic investigation to determine the source and possible spread of infection;

(c) take appropriate steps, as outlined in the "Control of Communicable Diseases Manual, An Official Report of the American Public Health Association", (18th edition, 2004), to prevent or control the spread of disease; and

(d) notify contacts as defined in ARM 37.114.101 of the case and give them the information needed to prevent contracting the disease.

(3) Whenever the identified source of a reportable disease or a person infected or exposed to a reportable disease who should be quarantined or placed under surveillance is located outside of the jurisdiction of the local health officer, the local health officer must:

(a) notify the department or the local health officer of the jurisdiction in which the source or person is located if within Montana; or

(b) notify the department if the source or person is located outside of Montana.
