SEOUL: South Korea on Saturday reported 18 fresh cases of the new coronavirus, including 12 in Seoul, as health workers scrambled to trace contacts following a slew of transmissions linked to clubgoers. The latest infections brought national totals to 10,840 cases and 256 deaths. While South Korea’s Centers for Disease Control and Prevention didn’t immediately release details, most of the new cases were likely linked to nightclubs in Seoul’s Itaewon leisure district, which was brought to a sudden standstill Friday night following reports of the transmissions. At least 15 cases were linked to a 29-year-old man who visited three Itaewon clubs last Saturday and later tested positive for the virus. It raised concern about a broader spread of the virus in the Seoul metropolitan area, where about half of South Korea’s 51 million people live. Prime Minister Chung Sye-kyun in a meeting Saturday said the government will employ “all available resources” to find and isolate carriers. Officials have also issued a monthlong administrative order advising nightclubs, hostess bars and other similar facilities nationwide to close. Fewer cases in previous weeks had allowed for social distancing guidelines to be relaxed and a phased reopening of schools, starting with high school seniors returning next Wednesday.
