Also a personal pet peeve.
People that want to compare the fatality rates between the flu and COVID are demanding 2 separate standards for each virus. The flu deaths given by the CDC are estimated and not confirmed cases. If you go with just confirmed cases the total is much, much, much smaller. For COVID the demand confirmed cases only and then if they have a co-morbidity they want to pawn it off on the co-morbidity. It is pretty easy to tell the difference somebody that dies from leukemia vs COVID.
