South Korea warned of a second wave of the new coronavirus on Sunday as infections rebounded to a one-month high, just as the authorities were starting to ease some pandemic restrictions, according to Reuters. "It's not over until it's over," President Moon Jae-in told the nation, saying a new cluster shows the virus can spread widely at any time, and warning of a second wave late this year. The Korea Centers for Disease Control and Prevention (KCDC) reported 34 new infections, the highest since April 9, after a small outbreak emerged around a slew of nightclubs, prompting the authorities to temporary close all nightly entertainment facilities around the capital. The death toll remained at 256. The daily tally of new infections had hovered around 10 or less in recent weeks, with no or very few domestic cases over the past 10 days.
