We present and compare COVID-19 attack rates for infection, hospitalization, admission to intensive care unit (ICU), and death, in health care workers (HCW) and non-HCWs in nine European countries from 31 January 2020 to 13 January 2021. Adjusted attack rate ratios in HCWs (compared to non-HCWs) were 3.0 [95% confidence interval: 2.2-4.0] for infection, 1.8 [1.2-2.7] for hospitalization, 1.9 [1.1-3.2] for ICU admission and 0.9 [0.4-2.0] for death. Among hospitalized cases, case-fatality ratio was 1.8% in HCWs and 8.2% in non-HCWs. Differences might be due to better/earlier access to treatment, differential under-ascertainment, and to the healthy worker effect.
