Barry, I do not believe I am saying anything other than IFR and CFR are often mixed up.

I saw a three paragraph article in a news paper about the confusion between IFR and CFR. I then got the four numbers directly from WHO and CDC press releases.

Are you saying that 95% to 97% of flu infections are asymptomatic (“cases” vs “infections”)? What is a source for this?

IFR = infection fatality rate

CFR = case fatality rate

A "case"requires symptoms.

Seasonal flu has an IFR of 0.1% and a CFR of 2-3%
