The mortality rate of the seasonal flu vs CV19 can certainly be calculated, but the lethality difference can’t be accurately determined without a controlled study.
“The mortality rate of the seasonal flu vs CV19 can certainly be calculated, but the lethality difference can’t be accurately determined without a controlled study.”
You can’t do a “controlled study” of lethality of diseases - you can’t intentionally expose 1000 people to covid19 and 1000 to regular flu just to find out which group dies at a higher rate.
I think this study establishes the mortality rate of Covid19.
Estimated case mortality is about 1.3, infection mortality (taking into account those whose had mild or no symptoms) is about .7%. For flu it is accepted that the infection mortality is less than .1%, but if you have evidence otherwise please provide a link - and not to a newspaper article or blog post from “impimp”
