Age-specific mortality and immunity patterns of SARS-CoV-2

Estimating the size and infection severity of the SARS-CoV-2 epidemic is made challenging by inconsistencies in available data. The number of COVID-19 deaths is often used as a key indicator for the epidemic size, but observed deaths represent only a minority of all infections. Additionally, the heterogeneous burden in nursing homes and variable reporting of deaths in elderly individuals can hamper direct comparisons across countries of the underlying level of transmission and mortality rates. Here we use age-specific COVID-19 death data from 45 countries and the results of 22 sero prevalence studies to investigate the consistency of infection and fatality patterns across multiple countries
