SEOUL - A South Korean city that is home to the largest US overseas military base has asked for coronavirus tests on American soldiers before they arrive, amid concerns over a recent spike in imported cases, officials said on Wednesday.

US Forces Korea (USFK) has reported at least 25 virus infections among its troops and employees in the past two weeks, including 11 on Monday

US Forces Korea (USFK) has reported at least 25 virus infections among its troops and employees in the past two weeks, including 11 on Monday. All were confirmed upon arrival or while spending two weeks in mandatory quarantine.

The surge has prompted Pyeongtaek, home to the sprawling Camp Humphreys south of Seoul, to ask the government to request a pre-departure test for incoming US soldiers, a city official said.

“Luckily there’s no infection within the base reported so far, but we thought a prior test could curb the numbers and soothe concerns among residents,” the official told Reuters.

The USFK did not respond to a request seeking comment. But it has said it is taking aggressive quarantine measures, with fewer than 1% of active duty personnel having tested positive.

All arrivals face a test, two weeks in isolation and a second test before release.

On Monday, health ministry official Son Young-rae described US authorities’ response to the virus as “extremely strong”, adding that both sides are in close consultation on further steps.
