Ohio Rev. Code § 3707.08
When a person known to have been exposed to a communicable disease declared quarantinable by the board of health of a city or general health district or the department of health is reported within its jurisdiction, the board shall at once restrict such person to his place of residence or other suitable place, prohibit entrance to or exit from such place without the board's written permission in such manner as to prevent effective contact with individuals not so exposed, and enforce such restrictive measures as are prescribed by the department.
When a person has, or is suspected of having, a communicable disease for which isolation is required by the board or the department, the board shall at once cause such person to be separated from susceptible persons in such places and under such circumstances as will prevent the conveyance of the infectious agents to susceptible persons, prohibit entrance to or exit from such places without the board's written permission, and enforce such restrictive measures as are prescribed by the department.
When persons have, or are exposed to, a communicable disease for which placarding of premises is required by the board or the department, the board shall at once place in a conspicuous position on the premises where such a person is isolated or quarantined a placard having printed on it, in large letters, the name of the disease. No person shall remove, mar, deface, or destroy such placard, which shall remain in place until after the persons restricted have been released from isolation or quarantine.
Physicians attending a person affected with a communicable disease shall use such precautionary measures to prevent its spread as are required by the board or the department.
No person isolated or quarantined by a board shall leave the premises to which he has been restricted without the written permission of such board until released from isolation or quarantine by it in acordance with the rules and regulations of the department.
