Nice new site http://91-divoc.com/pages/covid-visualization/ that plots time trends in cases and deaths, total numbers and rates per million population. The time axis is days since 100+ cases/deaths or days since 1 case/death per million population. I’ve attached screenshots of cases/million and deaths/million with Switzerland highlighted. The dotted straight line on the log scale represents a daily growth rate of 1.35 (35% more cases than day before). That corresponds to a doubling time of 2.31 days. Fortunately, most curves are showing some flattening after the first 10 days to around 1.2 or lower. Australia has a curve that corresponds to a daily growth rate of 1.2. That difference is huge. At a daily growth rate of 1.35, the first case becomes 3.2 million after 50 days, whereas at 1.2 it becomes 9,100. Most of the countries that are beyond 15 days from first case/million are showing flattening of growth, and in the case of China its almost completely flat.

The USA is on day 20 since 100 confirmed cases (or day 18 since 1 case/million) and is following the 1.35x line very closely so far. Unlike most other countries this far into the epidemic, it is not yet showing signs of slowing down.  US total confirmed cases will overtake those of Italy and China by tomorrow or day after.
