When complaint is made or a reasonable belief exists that an infectious or contagious disease prevails in a house or other locality which has not been reported as provided in section 3707.06 of the Revised Code, the board of health of a city or general health district shall cause such house or locality to be inspected by its health commissioner, and on discovering that such disease exists, the board may send the person diseased to a hospital or other place provided for such person, or may restrain him and others exposed within such house or locality from intercourse with other persons, and prohibit ingress and egress to or from such premises.
