Spike in South Korea virus cases shows perils of reopening. (Omaha World Herald, 5/27/2020)
In South Korea, 40 newly confirmed cases — the biggest daily jump in nearly 50 days — raised alarms as millions of children returned to school Wednesday.
All but four of the new cases were in the densely populated Seoul region, where officials are scrambling to stop transmissions linked to nightclubs, karaoke rooms and a massive e-commerce warehouse. All were reopened last month when social distancing measures were relaxed.
The number of active cases in South Korea peaked on March 11 -- 79 days ago.
The U.S. is still peaking.
