Compared with the 2021‑2022 influenza season, for sentinel surveillance the number of tested specimens has
doubled, with a 4‑fold increase in influenza detections.
As autumn moves to winter, the WHO/Europe, EC and ECDC are issuing a clear, urgent message: people who remain unprotected against both COVID-19 and seasonal influenza – especially the most vulnerable and at-risk – should take up any offer for vaccination to prevent or mitigate the impact of these co-circulating respiratory infections.
This issue of the ECDC Communicable Disease Threats Report (CDTR) covers the period 1 - 7 October 2023 and includes updates on dengue, West Nile virus disease, COVID-19, chikungunya, Middle East respiratory syndrome, mpox, and mass gathering monitoring for the Rugby World Cup.
