The very early reports from China put the case fatality rate at 15%. The pattern is for the (reported) CFR to go down very quickly. > The trend in mortality reporting for COVID-19 has been typical for emerging infectious diseases. The case fatality rate (CFR) was reported to be 15% (six of 41 patients) in the initial period,1 but this estimate was calculated from a small cohort of hospitalised patients. Subsequently, with more data emerging, the CFR decreased to between 4·3% and 11·0%,2, 3 and later to 3·4%.4 The rate reported outside China in February was even lower (0·4%; two of 464).5 [1] https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(20)30244-9/fulltext https://www.thelancet.com/journals/laninf/article/PIIS1473-3...
