Age-stratified infection fatality rate of COVID-19 in the non-elderly informed from pre-vaccination national seroprevalence studies | medRxiv

This study by Dr John Ioannides, et al. is highly educational, because the infection fatality rate (IFR) is a key statistic for an emerging virus.

The study looked at the infection fatality rate (IFR) for covid-19 around the world.

The most fascinating paragraph was this one:

"The median IFR was 0.0003% at 0-19 years, 0.003% at 20-29 years, 0.011% at 30-39 years, 0.035% at 40-49 years, 0.129% at 50-59 years, and 0.501% at 60-69 years."

The authors do an excellent job describing how they collected their data. The authors also do an excellent job listing the potential flaws of their study.

In my opinion, John P.A. Ioannidis, MD, who has multiple degrees, is one of the best physician mathematicians in the world.
