Respiratory virus trends across the EU/EEA continue to show early signs of decline. RSV circulation remains high, with children under five most affected. Influenza circulation and hospitalisations are decreasing. SARS CoV 2 activity remains low.
This Reporting Protocol describes data collection for influenza, COVID-19, and other respiratory viruses (such as RSV or new viruses of public health concern) in the EU/EEA and wider WHO European Region. Data collection is integrated for most datasets in line with the operational considerations for respiratory virus surveillance in Europe.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 28 February–6 March 2026 and includes updates on respiratory virus epidemiology in the EU/EEA, Sars-CoV-2 variant classification, MERS, mass gathering monitoring, and chikungunya.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 21 - 27 February 2026 and includes updates on respiratory virus epidemiology in the EU/EEA, mass gathering monitoring, chikungunya, cholera, and swine flu.
Respiratory virus trends across the EU/EEA show early signs of decline. RSV activity remains high, with young children most affected. Influenza circulation remains widespread, but continues to decrease in most countries. SARS CoV 2 activity remains low.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 7 - 13 February 2026 and includes updates on respiratory virus epidemiology in the EU/EEA, mass gathering monitoring, avian influenza, and mpox.
Respiratory virus activity remains elevated across the EU/EEA: influenza transmission is still widespread but decreasing, and RSV levels remain high, while SARS CoV 2 circulation remains low.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 7 - 13 February 2026 and includes updates on respiratory virus epidemiology in the EU/EEA, mass gathering monitoring, avian influenza, chikungunya, dengue, Nipah virus disease, and measles.
Respiratory virus circulation is elevated across the EU/EEA: the circulation of influenza viruses is still high and RSV circulation is elevated and increasing. SARS-CoV-2 circulation continues to be low.
