Silverman and Washburne found that the coronavirus mortality rate could be as low as 0.1 percent, “similar to that of flu.”
The Economist further explained:
COVID-19 takes 20-25 days to kill victims. The [Silverman and Washburne] paper reckons that 7m Americans were infected from March 8th to 14th, and official data show 7,000 deaths three weeks later. The resulting fatality rate is 0.1%, similar to that of flu. That is amazingly low, just a tenth of some other estimates. Perhaps it is just wrong, possibly because the death toll has been under-reported. Perhaps, though, New York’s hospitals are overflowing because the virus is so contagious that it has crammed the equivalent of a year’s worth of flu cases into one week.
