New surveillance updates and guidance for mosquito-borne diseases
As Europe enters the 2025 mosquito season, ECDC is launching surveillance updates and guidance to help public health authorities tackle and monitor mosquito-borne diseases in a timely way.
In 2025, ECDC celebrates 20 years of strengthening Europe’s defences against infectious diseases and protecting the health of over 500 million people across the EU.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 12-18 July 2025 and includes updates on dengue, chikungunya virus disease, Crimean-Congo haemorrhagic fever, West Nile virus infection, respiratory virus epidemiology in the EU/EEA, Influenza A(H5N1), mpox, Nipah virus disease and mass gathering monitoring of UEFA Women's EURO 2025 in Switzerland.
This report gives an overview of the countries and areas where dengue cases – and their corresponding case numbers - have been reported to the European surveillance portal for infectious diseases (EpiPulse).
