Highlights

  • Across 31 systematically identified national seroprevalence studies in the pre-vaccination era, the median infection fatality rate (IFR) of COVID-19 was estimated to be 0.034% for people aged 0–59 years and 0.095% for those aged 0–69 years.

  • The median IFR was 0.0003% at 0–19 years, 0.002% at 20–29 years, 0.011% at 30–39 years, 0.035% at 40–49 years, 0.123% at 50–59 years, and 0.506% at 60–69 years.

  • At a global level, pre-vaccination IFR may have been as low as 0.03% and 0.07% for 0–59 and 0–69 year old people, respectively.

  • These IFR estimates in non-elderly populations are lower than previous calculations had suggested.”
