Here is a plot of history since the end of April. New cases per day per 100k population. Shown are states and counties where I have family. Data is as recorded by me each evening from the Alabama public health dashboard
and from the Florida "community" dashboard
, and from Wikipedia articles for the United States
, and France
. France and Germany are between 0.5 and 1 almost the whole time. That is what successful test-and-trace looks like. Slow, sporadic spread from contained local outbreaks.
