IFR is not a fixed value and is affected by many things. For example, intial viral load may be higher in NYC than many other places, vitamin D levels, air pollution, etc. There is no single IFR for any disease.
Yes, IFR is not a fixed value. But a range (0.1-0.6%) was provided by the person I was responding to. Even assuming NYC hit the top of the range of IFRs (which seems questionable given that NYC isn't a particularly old city), one would need an infection rate of 50%, which contradicts serology studies that turned out to be half that.
IFR in other locations (e.g. small towns in Europe where blood tests show widespread exposure) has also consistently come in at roughly 1%.
To prove that 0.1-0.6% is wrong, one only needs to show a single example that had an IFR > 0.6%. I provided several. You meanwhile have provided none.
And this range of IFR estimates (~0.7-1.1%) is what you tend to see across localities where serological tests result in substantial positive antibody rates. Studies based on low (e.g. <5%) exposure rates aren't that meaningful because false positives can dwarf the true-positives, skewing the results.
And so, so mare which I don’t have time to find one by one right now. Like the study from Finland, or other places.
I don’t have anything to add to this discussion, since this clearly shows you are incapable of research. One other point is there is non negligible amount of people who does not develop antibodies therefore they are not detected in serological tests. I would expect IFR go down.
The only required skill required is googling and having open mind.)
“ Iceland, (1st May) reports ten deaths in 1798 patients, CFR. 0.56%. If we assumed 1% of the population (364,000) is infected, then the corresponding IFR would be 10/3640 = 0.3%. Iceland’s test and quarantine measures may have shielded the elderly group, and deaths may still go up as they lag infection by about two weeks.
Iceland’s higher rates of testing, the smaller population, and their ability to ascertain all those with Sars-CoV-2 means they can obtain. an accurate estimate of the CFR and the IFR during the pandemic (most countries will only be able to do this after the pandemic).
Current data from Iceland suggests their IFR is somewhere between 0.3% and 0.56%.”

P.S. FYI Iceland has done more test than anybody I think (ratiowise).
IFR in other locations (e.g. small towns in Europe where blood tests show widespread exposure) has also consistently come in at roughly 1%.
