I wonder what happened to USDS? Does it still exist? A need for an "official" version of such a thing is pretty obvious, yet the CDC website is pretty much worse than nothing at all, because people go there, and whatever data they have is not only incomplete, it's also a few days behind. They also don't update it over the weekend, as far as I can tell.
The situation is not great, to be sure. Check out covidtracking.com, which is aggregating data from state health department sites. I think that's the best going at the moment.
