Currently, the U.S. as a whole is seeing 31 new COVID-19 cases / 100K / day.
Daily new COVID-19 cases for the The U.S. are now 40% lower than at the 9/1/2021 peak of the Delta wave.
That 40% decline since 9/1/2021 is made up of:
- Three regions (South Atlantic, South Central, Pacific) where daily new cases are down by about half.
- Three regions (Northeast, Midwest, Mountain) where daily new cases are roughly unchanged.

Final update on the Virginia school reopening analysis
Because this is a post about nothing much new happening, I thought I’d update my analysis of the impact of K-12 opening in Virginia. Fears about school reopening seem to have faded — in Virginia, at least — so it’s a pretty good bet that a) once again, I’ll see nothing and b) there’s no practical point to continuing this.
Recall that I’m using the staggered opening dates of K-12 schools across Virginia as a “natural experiment”. If school reopening generates a lot of new cases, we ought to see the share of new cases attributable to the school-aged population rise.
But that’s not happening. Maybe there’s a little upward drift. Maybe not. But it bears no relationship to when K-12 schools opened.
