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 10/16/2020 was 213 days, passing through 218,000 deaths. A graph of the doubling time is shown here.
