“The recent spike in Covid-19 cases in some of the countries thought to have best contained the virus — first Singapore, now South Korea and, potentially, Germany — is a glimpse into America’s possible future as states start reopening businesses and public activities after several months of lockdown.
All it can take to reverse the positive trends is a single undetected case. As Vox’s Alex Ward reported this week, one South Korean man who went out for a night on the town at several Seoul dance clubs has been linked to nearly 80 new cases there. Suddenly the country’s curve is rising again and the local government ordered bars and restaurants to be closed, an abrupt reversal of its reopening plans.”
