Every month ECDC provides detailed epidemiological overview of the worldwide transmission of chikungunya in its weekly threat report (Communicable Diseases Threat Report).
The food-borne infections listeriosis and shigatoxigenic Escherichia coli are increasing in the EU/EEA and were in 2022 at levels higher than before the COVID-19 pandemic.
The mosquito species Aedes albopictus, a known vector of chikungunya and dengue viruses, is establishing itself further northwards and westwards in Europe, according to the latest data.
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.
