In many European countries and the US, confirmed coronavirus cases double every 2nd to 3rd day. China, South Korea, Japan and Hong Kong have flattened the curve already.
Cumulative numbers of confirmed cases in selected countries after the 100th case, last updated on March 12. These numbers don't tell us anything about the number of infected people, just about the number of people who got tested positive.
The chart stops at day 35, but more than 50 days have passed since China reported their 100th case. China reported almost 80,800 to date. The 100th cases of all countries are aligned and therefore approximated.
