South Korea has turned its former Olympic stadium into a screening center to test all overseas arrivals. The country's reported COVID-19 cases totaled 10,062 as of midnight on April 3.
The daily caseload has stayed around 100 since the end of March, but small-cluster infections and imported cases can still be found.
The complex for the 1988 Summer Olympics was adapted into a temporary COVID-19 test site for people arriving on international flights, and has the capacity to test 1,000 people per day.
Visitors without local addresses are being forced to stay in quarantine at government-designated facilities at their own expense.
