Estimating the wave 1 and wave 2 infection fatality rates from SARS-CoV-2 in India

Summary: This study aimed to estimate the infection fatality rate of COVID-19 using seroprevalence data. The findings showed that the infection fatality rate varied significantly across different locations due to differences in population age structure, case mix of infected and deceased patients, and other factors. The inferred infection fatality rates were generally lower than earlier estimates made during the pandemic.
