By the end of Monday 22nd February 2021, we will pass through and above 500,000 deaths from COVID19 in the United States. I calculate and plot the doubling time in days averaged over a moving 7-day period. Doubling time, based on the previous seven days average, as of the end of 2020 had dropped below100 days. The doubling time for US deaths from COVID19 is increasing again early in 2021, as seen in the current graph below.
|Changes in doubling time (days) for deaths from COVID19 in the United States.|
(Many deaths in some states were being classified as "pneumonia" previously, and are not part of the COVID19 official deaths count, so more deaths have occurred from COVID19 in the United States than the CDC data indicate.)
