Chart update thread: CNN now reports 933,993 known US #COVID19 infections. https://www.cnn.com/interactive/2020/health/coronavirus-us-maps-and-cases/ This is an increase of 5%, the single largest number of new cases so far (43,469 reported). The last-five-day-average growth goes back to 4%. 49-day average is 17%.

The gigantic decline from Thursday to Friday (-33%), followed by the even bigger growth since yesterday (250%), seems volatile, but it seems like it is probably due to testing rather than swings in infections.

Indeed, if you take it from Tuesday, there was a decline in growth of 55% to Friday, followed by more than doubling of growth overnight. But the testing has been all over the place, as has the updating of results by states.

Today was another huge day in testing (almost 301,000 reported!); partly backlogs, partly new results. https://twitter.com/COVID19Tracking/status/1254156424243933184

. @COVID19Tracking is reporting a total positive rate of 18%, which is a needed decline.

Upshot of all of this is: 110k new positives in the last 4 days; 200k new positives in the last week (27% of all known cases); and likely hitting 1m known positives on Monday or Tuesday. *We are nowhere near the end of this.*
