A U.S. Marine at Fort Belvoir, Virginia, has tested positive for COVID-19, becoming the state’s first case of coronavirus, the Department of Defense announced in a tweet late Saturday.

Chief Pentagon spokesman Jonathan Hoffman tweeted that “the Marine recently returned from overseas where he was on official business. Defense Secretary Mark Esper and the White House have been briefed.”

A Defense Department official told The Associated Press on background prior to the public announcement that this is the first reported U.S. military case inside the country.

The Virginia Department of Health said in a press release that ” evidence has not been seen of COVID-19 spreading in Virginia,” and the risk to the public remains low.
