Kudos to Delaware (@Delaware_DHSS) for getting new race/ethnicity testing data up. They are the third state to provide this crucial information.

The variation between states/territories is also fascinating. DC told the Washington Post it doesn't report probables because it doesn't have any. Delaware, meanwhile, with a comparable total case count, reports nearly 1,000 probable cases.

States reported 775 deaths, but as @youyanggu noted, the change from last week was due to a reporting backlog in Delaware. https://t.co/unbw0PtJ2H https://t.co/IqniAMx1D6

Here's the continuing best news: deaths have not turned upward.

And the death numbers today and yesterday have been too high as they reflect Delaware (yesterday) and Arizona (today) rectifying undercounting of COVID-19 deaths from previous days. https://t.co/lvzuaLEs18

(Corrected previous tweet—Delaware reviewed death records; they did not count new probable deaths.) https://t.co/3kFc0P7VRn

Zooming into the state level, more than 10 states broke case records today: AK, AR, AZ, DE, IN, MA, ME, NJ, PA, RI, and VT. Note: AZ had a higher count on Dec. 1, but it was a data backlog. https://t.co/ao6T6EQxiH
