Hepatitis A cases in 2021 were at their lowest levels since EU-level hepatitis A surveillance began in 2007, while five other food and waterborne diseases are rising towards pre-pandemic levels. The information is revealed in the Annual Epidemiological Report 2021, of which six chapters are published today by ECDC.
In 2021, 30 EU/EEA countries reported 3 864 cases of hepatitis A (Table 1). The EU/EEA notification rate was 0.9 cases per 100 000 population. In 2021, both the lowest number of reported cases and the lowest notification rate were reported since the beginning of EU-level hepatitis A surveillance in 2007. The total number of hepatitis A cases reported in EU/EEA countries in 2021 represented a decrease of 65.7% and 12.3% compared to 2019 and 2020, respectively.
