Driving the news: South Korea has begun relaxing social-distancing requirements. But a new cluster of coronavirus cases has emerged, stemming from a 29-year-old who visited three nightclubs in Seoul last Saturday before testing positive for the virus on Wednesday, Bloomberg notes.

The number of cases tied to the patient jumped to 40 as of Saturday afternoon, per Bloomberg. South Korean epidemiologists began tracing roughly 1,500 people believed to have been in those clubs around the same time, per the New York Times.

Seoul Mayor Park Won-soon on Saturday ordered all nightclubs, discos, hostess bars and other nightlife establishments to close as a result.
