Wisconsin Statutes Health (Ch. 250 to 255) § 252.03. Duties of local health officers

(1) Every local health officer, upon the appearance of any communicable disease in his or her territory, shall immediately investigate all the circumstances and make a full report to the appropriate governing body and also to the department. The local health officer shall promptly take all measures necessary to prevent, suppress and control communicable diseases, and shall report to the appropriate governing body the progress of the communicable diseases and the measures used against them, as needed to keep the appropriate governing body fully informed, or at such intervals as the secretary may direct. The local health officer may inspect schools and other public buildings within his or her jurisdiction as needed to determine whether the buildings are kept in a sanitary condition.

(2) Local health officers may do what is reasonable and necessary for the prevention and suppression of disease; may forbid public gatherings when deemed necessary to control outbreaks or epidemics and shall advise the department of measures taken.

(2j) A local health officer may not issue a mandate to close any business in order to control an outbreak or epidemic of communicable disease for longer than 30 days unless the governing body of the political subdivision in which the order is intended to apply approves one extension of the order, not to exceed 30 days. A mandate to close more than one business as provided under this subsection may not distinguish between essential and nonessential businesses. In this subsection, “political subdivision” means a city, village, town, or county.

(3) If the local authorities fail to enforce the communicable disease statutes and rules, the department shall take charge, and expenses thus incurred shall be paid by the county or municipality.

(4) No person may interfere with the investigation under this chapter of any place or its occupants by local health officers or their assistants.
