The other three installations selected to house evacuees are the 168th Regiment, Regional Training Institute in Fort Carson, Colorado; Lackland Air Force Base in San Antonio, Texas; and the Marine Corps Air Station Miramar, California, according to a statement from Jonathan Rath Hoffman, assistant to the Secretary of Defense for public affairs.

There are now eight confirmed U.S. cases of coronavirus, including one in Santa Clara County that was announced on Friday.

Health officials announced the latest U.S. case on Saturday in Boston, Massachusetts, of a man in his 20s who had recently traveled to Wuhan, China.

On Friday, Alex Azar, head of the U.S. Department of Health and Human Services, declared a public health emergency due to the spread of the virus and said that anyone who had traveled to Hubei Province in China, where Wuhan is located, within the past 14 days, will be subject to a quarantine of up to 14 days.
