The state director of health is empowered to establish and strictly maintain quarantine at such places as he may deem proper and forbid and prevent the assembling of the people in any place, when the state director of health or any county or municipal health officer deems that the public health and safety so demand, and the state board of health may adopt rules and regulations to obstruct and prevent the introduction or spread of smallpox or other communicable or infectious diseases into or within the State, and the state director of health shall have the power to enforce these regulations by detention and arrest, if necessary. The state director of health shall have power to enter into any town, city, factory, railroad train, steamboat or other place whatsoever, and enter upon and inspect private property for the purpose of investigating the sanitary and hygienic conditions and the presence of cases of infectious diseases, and may, at his discretion, take charge of any epidemic or endemic conditions, and enforce such regulations as the state board of health may prescribe. All expenses incurred in controlling any endemic or epidemic conditions shall be paid by the county or municipality in which such epidemic occurs.
