True. Would have to look back and see if they were predicting a similar rate going forward.
You’re missing the distinction: they were estimating the case fatality rate (CFR) while this study is assessing the infection fatality rate (IFR).
The IFR was estimated at somewhere around .2% back in 2020, with the great majority of deaths occurring in those 65+. This study appears to confirm those early estimates.
Early CFR estimates were assumed to be high for several reasons, including scarcity of testing, fear of going out to get tested, and poor recognition of symptoms.
