SEOUL, South Korea—South Korea on Wednesday confirmed its first five cases of the new Omicron coronavirus variant in people linked to arrivals from Nigeria, prompting the government to tighten the country’s borders.
The Korea Disease Control and Prevention Agency said Wednesday the cases include a couple who arrived from Nigeria on Nov. 24 and a friend who drove them home from the airport. The two other cases were women who also traveled to Nigeria and returned to South Korea on Nov. 23.
