Ohio Rev. Code § 3707.20
No person, who has a contagious or infectious disease, or who has been exposed to a contagious or infectious disease, may be sent or admitted to a prison; jail; workhouse; infirmary; children's home; state hospital or institution for persons who are blind, persons with mental illnesses, or persons with intellectual disabilities; school for the blind or deaf; or other state or county benevolent institution without first making known the facts concerning the illness or exposure to the superintendent or other person in charge thereof. When a dangerous, contagious, or infectious disease is in a jail or prison and a prisoner in the jail or prison exposed to the disease is sentenced to a state correctional institution, the prisoner shall be confined and isolated in the jail or prison or other proper place, upon the order of the proper court, for any time that is necessary to establish the fact that the prisoner has not contracted the disease.
