Infectious or communicable disease

When any infectious or communicable disease is reported to a health officer or when the health officer has reason to suspect that such disease exists within the officer's jurisdiction, the officer shall make a thorough investigation, if necessary, and if such disease is found to exist, the officer shall take such steps as are required by the laws of the state and by this chapter. If upon investigation the health officer shall find that a disease for which isolation is required has recently existed on any premises within the officer's jurisdiction, the officer shall place such premises under surveillance until the expiration of the incubation period.
