SEOUL -- South Korea is aggressively testing and tracing thousands of people who went to nightclubs in central Seoul, in a bid to prevent an explosion of infections from a new coronavirus cluster.
Health authorities said Wednesday they were confirming the identity of the clubbers in the nightlife district of Itaewon between April 24 and May 6. They are reviewing guest books and credit-card payments at venues, and asking telecom companies to provide location information of people who are suspected of being infected.
