Similar to the previous post about case growth rates in US states, growth rate are declining in most countries.

The global average for the decline in growth rates is about .9% per day. Extrapolating this decline would result in countries hitting zero new cases per day at about 40 days from when then hit 100 cases. China had a growth rate of .7% ad day 40, and less than .1% at day 52. A more accurate prediction model would be non linear, which is had to see in most of these plots, except for South Korea, which clearly shows the approach to zero.
