COVID-19 Fatality Statistics

As part of my editorial work, I am studying some papers this morning on COVID-19, so as to (maybe) obtain a philosophical article from data scientists. So I presumably have the latest and most comprehensive statistics, passed on to me by a laboratory in Vienna. What is reported here -- I'll take the specific case of China -- is a "very low" CFR (case fatality risk). Up to 50 years of age, the total CFR is 0.2%. Up to 60, 0.4%, up to 70, 0.8%. Include people older than 70, and the CFR shoots up. The CFR of health workers (a well monitored group) is 0.3%. A major influence on CFR is already-questionable health. A surprise for me is that farm labourers are at special risk, with 1.4% CFR. The researchers point out that their studies include a "very large number of cases", which both helps and hinders their calculations. OBSERVATION: This is the CFR among (more or less) confirmed cases. The mortality rate in the whole population is about 0.0002%.

POSTSCRIPT: It seems that the fatality statistics above are very much too high. The latest from the BBC: https://www.bbc.com/news/health-51979654 But my post of 29 March presaged this.
