It is extremely belated. We know this. But the CDC is finally getting some real information up and online. The key page is here, Coronavirus Disease 2019 (COVID-19) Situation Summary. There are links toward the upper left to a series of charts and graphs on cases in the US, testing in the US and more.
From a brief review a significant amount of data still seems to be behind some other non-government sources of information – like the COVID-19 Tracking Project I’ve been referencing and the Johns Hopkins Global Survey. Aggregate numbers of daily tests for instance seems to fall off from March 9th and there are only 8 listed on March 10th, yesterday. Still, it seems to be a real step in the right direction and I’d imagine it will improve over time.
Some pages still have the notation that the data will only be updated Monday through Friday; on other pages that flag has been removed and replaced with a new one that says information will be updated as new data becomes available. So work in progress. But a step in the right direction.
