TRI-CITIES, Wash. — About 220 officers and inmates at a Washington state prison have tested positive for COVID-19, nearly double since restricting movement in its medium-security unit last month.

The state Department of Corrections brought in the Washington National Guard last week to administer coronavirus testing at the Coyote Ridge Corrections Center. The Tri-City Herald reported the results showed 171 inmates and 47 staff members tested positive Tuesday. Two inmates died.

Coyote Ridge, located in Connell, has minimum- and medium-security units. Officials say all employees in both units, and all inmates in the medium-security unit, will be regularly tested.
