Estimated Case Fatality Rate (CFR)

This chart estimates the Case Fatality Rate (CFR) by dividing the 21 day trailing average of daily deaths by the trailing average of the number of new confirmed cases with a lag of 18 days.

The number for January 6, 2021 is 1.224%, meaning that for 81 cases on December 19th average there was one death on January 6th, 2021.

The 18 day lag is based on examining the case and death charts, and has varied from 8 days in April to 20.5 days in August.
