CFR only includes resolved cases. That from multiple sources including actual doctors. So the CFR is 3.9%. IFR includes active cases, so it is 2.5%.
I’m not the one conflating CFR and IFR. That’s you.
IFR for the flu, a point on which we agree, is 0.1%. It is a historical measure used with historical data and in that calculation the cases have virtually all resolved. But this isn’t the flu, anyway. Pretending it is has already killed a lot of people.
You keep posting about NYC, but that isn’t even the city the article is about. You are deliberately inserting junk claims into the discussion in order to muddy the waters so your bogus claims might pass without scrutiny. That’s a dirty liberal trick.
Your article also does not say what you seem to think it says, and you neglected to include in your claims all the caveats the authors used for their study.
For NYC, it’s simple - Cuomo moved the deaths out of the city by exporting the sick. He also encouraged (inadvertently) exodus NY, which affected the whole eastern seaboard. That makes NYC unsuitable for any objective study. And, again, this isn’t just about NYC, and per the OP’s article, not about NYC at all.
IFR includes postiive antibodies and was 0.26% in Indiana. Read the paper I linked. Read the comments afterwards that claim that 0.26 is too low. Some of that is legit.
