The graph below is based on confirmed COVID19 death data reported from the CDC.
These numbers may lag slightly behind other US reporting sources and will underestimate the actual current death total from COVID19. For that reason, I have calculated and plotted the doubling time in days averaged over a moving seven day period. Doubling time based on the previous seven days average as of 11/16/2020 was 142 days, passing through 246,000 deaths. As of 11/22/2020 this has rapidly dropped to 119 days doubling time passing through 255,000 deaths from COVID10. A graph of the doubling time is shown here.
