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.
For 2021, 6 876 confirmed cases of yersiniosis (caused by Yersinia enterocolitica and Y. pseudotuberculosis) were reported by 28 EU/EEA countries with an overall rate of 1.9 cases per 100 000 population. This represented an increase of 11.8% on 2020 and the pre-pandemic period (2017−2019). As in previous years, Germany accounted for the highest number of cases, followed by France. These two countries accounted for 49% of all confirmed yersiniosis cases in the EU/EEA. Denmark had the highest notification rate of 7.8 cases per 100 000 population, followed by Finland, Lithuania and Czechia (Table 1, Figure 1).
Thirty-three percent of 1 649 yersiniosis cases with known information were hospitalised. No deaths were reported among the 3 659 cases with known outcome.
