ABSTRACT
We analysed 5,484 close contacts of coronavirus disease (COVID-19) cases in Italy, all tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Infection fatality ratio was 0.43% (95% confidence interval (CI) 0.21-0.79) for individuals younger than 70 years and 10.5% (95% CI 8.0-13.6) for older individuals. Risk of death after infection was 62% lower (95% CI 31-80) in clusters identified after 16 March 2020 and 1.8-fold higher for males (95% CI 1.03-3.16).
