A U.S. soldier here has tested positive for coronavirus, the first member of the U.S. Forces Korea to catch the disease, USFK headquarters said on its website Wednesday.

The new diagnosis came as the USFK was already on high alert after the wife of a retired soldier was confirmed to be infected on Monday.

The USFK said it "is implementing all appropriate control measures to help control the spread of COVID-19 and remains at risk level 'high' for [the] USFK peninsula-wide as a prudent measure to protect the force."
