There& #39;s been a resurgence in the myth that SARS-CoV-2, the virus that causes COVID-19, kills ~0.26% of the people it infects in the US.
In other words:
The infection fatality rate (IFR) is ~0.26%.

The USA& #39;s CDC formerly gave an IFR estimate of ~0.26%, without ever citing evidence for it:

The CDC& #39;s cited source is the paper from part 2/.
But that paper states it likely *under-estimates* IFR:
"[when only analysing those serosurveys that had a low risk of bias] the inferred IFR rises substantially to 0.76% (0.37-1.15%)"

Part 4/ stated that excess mortality shows COVID-19 deaths are under-estimated, and thus IFR is under-estimated.
If so, then this makes the IFRs on this thread ~25% larger, on average.
