Ohio Rev. Code § 3707.04
In time of epidemic or threatened epidemic, or when a dangerous communicable disease is unusually prevalent, the board of health of a city or general health district, after a personal investigation by its members or executive officer to establish the facts in the case, and not otherwise, may impose a quarantine on vessels, railroads, or other public or private vehicles conveying persons, baggage, or freight, or used for such purpose. The board may make and enforce such rules and regulations as are wise and necessary for the protection of the health of the people of the community or state, but the running of any train or car on any steam or electric railroad, or of steamboats, vessels, or other public conveyances shall not be prohibited.
A true copy of such quarantine rules and regulations shall be immediately furnished by such board to the department of health, and thereafter no change shall be made except by the order of the department or the board to meet a new and sudden emergency.
