South Korea on Sunday began conducting new coronavirus tests on all arrivals from Europe and requiring even those with negative results to undergo a 14-day self-quarantine as part of efforts to prevent any inflow of the virus from outside.

Starting at midnight, the government set in motion the screening measure for both its citizens and foreigners, amid growing concerns over a steady rise in the number of imported COVID-19 cases.

On Sunday, more than 8,510 people are to arrive in Korea from overseas. Of them, about 1,000 are from Europe, which has become a new front line in the global fight against the virus, with Italy having clocked more than 4,820 deaths.
