Background The infection fatality rate (IFR) of Coronavirus Disease 2019 (COVID-19) varies widely according to age and residence status. Purpose Estimate the IFR of COVID-19 in community-dwelling elderly populations and other age groups from seroprevalence studies. Study protocol: . Data Sources Seroprevalence studies done in 2020 and identified by any of four existing systematic reviews. Study Selection SARS-CoV-2 seroprevalence studies with ≥1000 participants aged ≥70 years that presented seroprevalence in elderly people; aimed to generate samples reflecting the general population; and whose location had available data on cumulative COVID-19 deaths in elderly (primary cutoff ≥70 years; ≥65 or ≥60 also eligible). Data Extraction We extracted the most fully adjusted (if unavailable, unadjusted) seroprevalence estimates and sampling procedure details. We also extracted age- and residence-stratified cumulative COVID-19 deaths (until 1 week after the seroprevalence sampling midpoint) from official reports, and population statistics, to calculate IFRs corrected for unmeasured antibody types. Sample size-weighted IFRs were estimated for countries with multiple estimates. Secondary analyses examined data on younger age strata from the same studies. Data Synthesis Twenty-three seroprevalence surveys representing 14 countries were included. Across all countries, the median IFR in community-dwelling elderly and elderly overall was 2.4% (range 0.3%-7.2%) and 5.5% (range 0.3%-12.1%). IFR was higher with larger proportions of people >85 years. Younger age strata had low IFR values (median 0.0027%, 0.014%, 0.031%, 0.082%, 0.27%, and 0.59%, at 0-19, 20-29, 30-39, 40-49, 50-59, and 60-69 years). Limitations Biases in seroprevalence and mortality data. Conclusions The IFR of COVID-19 in community-dwelling elderly people is lower than previously reported. Very low IFRs were confirmed in the youngest populations. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement No funding was received specifically for this work.

Un témoignage intense de Marie Carmen Lattuchella ayant perdu son mari le 9 août, quelques semaines seulement après qu’il avait reçu le vaccin. Son mari n’ayant eu aucun antécédent médical et prenant soin de sa santé, est parti dans son sommeil, sans qu'aucun signe n'ait pu laisser penser à ses proches qu’ils ne reverraient pas son sourire le lendemain.
