W. Va. Code § 16-3-2
The county board of health of any county may declare quarantine therein, or in any particular district or place therein, whenever in their judgment it is necessary to prevent the spread of any communicable or infectious disease prevalent therein, or to prevent the introduction of any communicable or infectious disease prevailing in any other state, county or place, and of any and all persons and things likely to spread such infection. As soon as such quarantine is established such board shall, in writing, inform the director of health thereof, the duty of whom it shall be to ascertain, as soon as practicable, the necessity therefor, if any exists, and if the state director of health finds that no such necessity exists, the same shall, by the said director, be declared raised. The said county board of health shall have power and authority to enforce such quarantine until the same is raised as aforesaid, or by themselves, and may confine any such infected person, or any person liable to spread such infection, to the house or premises in which he resides, or if he has no residence in the county, at a place to be provided by them for the purpose; and if it shall become necessary to do so, they shall summon sufficient guard for the enforcement of their orders in the premises. Every person who shall fail or refuse to comply with any order made by such board under this section, and every person summoned as such guard who shall, without a lawful excuse, fail or refuse to obey the orders and directions of such board in enforcing said quarantine, shall be guilty of a misdemeanor, and, upon conviction thereof, shall be fined not less than twenty-five nor more than two hundred dollars. In cases of emergency or actual necessity, and when the county commission or corporate authorities are from any cause unable to meet or to provide for the emergency or the necessity of the case, all actual expenditures necessary for local and county quarantine, as provided for in this section, shall be certified by the county board of health to the county commission, and the whole, or as much thereof as the said commission may deem right and proper, shall be paid out of the county treasury. The board of health of any city, town or village shall have, within the municipality, the same powers and perform the same duties herein conferred upon and required of the county board of health in their county. So far as applicable the provisions of this section shall apply to any quarantine established and maintained by the state director of health pursuant to section one of this article.
