That's what I was trying to get at earlier, I couldn't work out what all the mass of numbers were about and they made no sense. It seemed like half a data dump taken out of context.
The other issue of un-accounted for virus in the community and the
seroprevelance rate. To have the IFR drop to .23% that would assume in the US for instance that there is 10 times the cases in the community over documented.
The
seroprevelance rate study in Sydney found the rate to be barely 3 x the notified cases and that was from pretty sparse data, only 38 positives in 5000 tests. So that could possibly drop the current CFR from 2.6 to just over 0.8% IFR.
If you applied IFR to Influenza it would be like 0.0001%. Calculating IFR is basically witchcraft and educate guesswork due to trying to know what you don't know, if you knew, it would be CFR.
