New study of CFR for COVID-19 in Wuhan

The experts I follow on Twitter think this study is the best yet.   They suggest a case fatality ratio of 1.4% for symptomatic cases.   If there are many asymptomatic cases (there are clearly a non-trivial number, but we don't yet know how many), then the mortality rate for all infections even in Wuhan would be lower.  (This journalistic account of two studies suggests roughly 15-30% of cases may be asymptomatic.)  To put this in perspective:  even if the mortality rate ends up as low as 0.5%, it would still be five times worse than seasonal flu.  And that isn't counting the much higher rates for hospitalization associated with COVID-19 compared to flu.
