MARIN COUNTY, CA — A patient with the new coronavirus is being isolated at a hospital in Marin County, county officials announced Thursday. The patient was not infected in Marin, and no cases have been identified in Marin, officials added.

The patient with the virus, now known as COVID-19, was transferred Wednesday night from Travis Air Force Base in Solano County. The patient, who is not showing any symptoms but tested positive for the virus, is one of the evacuees from the quarantined Diamond Princess cruise ship in Japan.

The U.S. Centers for Disease Control & Prevention agreement with the Department of Defense requires any evacuee who tests positive to be moved from the base. Marin and other Bay Area counties are accepting these patients to reduce the burden on the Solano County health care system.
