Two days after South Korea reported their 100th COVID–19 case, they reported their 200th. Two days later, their 400th. Two days later, their 800th: South Korea had a doubling time of two days in the first 10 days of reporting their 100th case.
Since then, 27 days have passed. But instead of reporting their 1,759,943rd case yesterday, they reported their 8413th. South Korea has reduced their doubling time to 65 days.
