W. Va. Code § 19-9-14: Establishment of special quarantine.

The commissioner or his authorized agent shall have the power to establish and maintain a special quarantine, whenever any domestic animal shall be affected with or exposed to any communicable disease, or whenever he deems it necessary to have any animal examined or tested. When a special quarantine is established, the commissioner, or his agent, shall post on the building, structure, pen, coop, car, vessel, vehicle, field, or enclosure wherein the animal or animals quarantined are confined or contained, a notice declaring the quarantine and containing a description of the animal or animals and of the premises where quarantined. Such quarantine may continue for such time as the commissioner, or his agent, may deem advisable.
