The disease was first identified in Wuhan City in China, where the most cases and deaths have occurred.
Authorities took a little more than a week to completely lock down Wuhan City, but the virus spread to other parts of China and beyond.
Until recently, the place recording the second-highest number of cases so far was not actually a country, it was a cruise ship: the Diamond Princess.
However, now the second-highest number of cases have been confirmed in South Korea.
