Here’s the article at Covid.us.org: Excess Mortality due to the Pandemic, not the Disease. The CDC analyzed a period of nearly two months in 2020 (March 11 to May 2). In the previous year, that period saw 7,935 deaths. This year, there were 32,107 in the same period. Now you would think that those excess deaths were due to Covid-19, right? Confirmed and probably Covid cases combined for that period in NYC accounted for 18,879 deaths. That leaves 5,293 deaths above the usual level, not attributable to cases of Covid-19.
It seems that the pandemic causes deaths not only by means of the disease itself, but in other ways. The article discusses the possibilities.
