Fact check: CDC estimates COVID-19 death rate of 0.26% The range of estimates put the fatality rate for those showing symptoms between 0.2%-1%, with a "best estimate" of 0.4%. Roughly double that of the common flu does anywhere shut down for the flu? Why we're overestimating the mortality rate for COVID-19 A lack of adequate testing means many of those who have been infected with the coronavirus will not appear in official statistics. This suggests that many estimates for its mortality rate are much too high. We need to build better systems for sharing and reporting data.
