In South Korea, citizens have flattened the curve of the novel coronavirus — and it’s because of lessons they learned from fighting the MERS outbreak in 2015. Through a combination of aggressive and widespread testing measures, along with a system know as “contact tracing,” they’ve been better positioned to spot the path of the virus and curb its spread. While they are still vigilant for a second wave of Covid-19 cases, people in South Korea are slowly returning to public life. Watch the video above to find out how their testing and contact tracing measures work, and how it can be a lesson for countries still in lockdown.
