The Annual Epidemiological Reports (AERs) are a key ECDC publication on the epidemiology of communicable diseases of public health significance in Europe.
In the EU/EEA, respiratory virus activity is low. Influenza and RSV have decreased to low levels and in most countries. SARS-CoV-2 remains low, but it is important to remain vigilant for potential increases. Preventive measures, such as frequent handwashing, physical distancing, avoiding large gatherings, and wearing masks in healthcare settings can help reduce transmission and protect those at high risk of severe illness.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 3 May - 9 May 2025 and includes updates on Middle Eastern respiratory syndrome (MERS), and chikungunya virus disease.
