  1. Note: This table summarizes the dataset which combines the individual-level data released by the Federal Office of Public Health (February 25–May 15, 2020) and the seroprevalence results inferred from Stringhini et al. (2020). Panel A displays the number of estimated positive cases, as well as the share of total cases attributed to each age group. Panel B shows the number of patients requiring hospitalization or intensive care in each age group, also expressed as a share of the total number of cases in the corresponding age group. In case of access to intensive care units, the data even report the exact dates of entry and exit, allowing to compute the average length of stay. Finally, panel C displays the number of COVID-related deaths in each age group, indicating the corresponding imputed infection fatality rate and the share of total fatalities occurred among women
