Weekly Respiratory Virus Update — Week 43, October 2025
In the EU and EEA, the spread of respiratory syncytial virus (RSV) and influenza remains relatively low, though several countries report early signs of increasing activity. COVID-19 transmission, while still widespread, continues to drop steadily.
Health authorities advise considering vaccination against seasonal respiratory infections to reduce risks and severity.
About RSV
Respiratory syncytial virus is a frequent respiratory pathogen that typically leads to mild, cold-like illness. It affects people of all ages but can cause more serious infections in infants and the elderly.
About Influenza
Seasonal influenza is a preventable viral disease with mainly respiratory symptoms. The infection spreads easily through droplets, contact with contaminated surfaces, and indirect transfer from respiratory secretions.
