I thought I was done with poring over COVID case data. Things change.
I took a look at what is happening in the US on a state by state basis. It's stunning to see. The best metric for prevalence of COVID is number of cases adjusted for population. Specifically, I'm looking at the number of new cases over a seven day period per 100,000 residents. Through this prism the crisis is overwhelmingly concentrated in three contiguous states along the Mississippi River: Missouri, Arkansas and Louisiana. Plus Florida.
