ReviewInfection fatality rate of COVID-19 inferred from seroprevalence data.
To estimate the infection fatality rate of coronavirus disease 2019 (COVID-19) from seroprevalence data. ⋯ The infection fatality rate of COVID-19 can vary substantially across different locations and this may reflect differences in population age structure and case-mix of infected and deceased patients and other factors. The inferred infection fatality rates tended to be much lower than estimates made earlier in the pandemic.
