​​Today ECDC publishes its risk assessment on the 2012/13 seasonal influenza epidemics in Europe. Epidemics started earlier than in the previous season and western Europe and Scandinavia were the first affected areas.

ECDC monitors and reports on influenza transmission and virus circulation in Europe on a weekly basis throughout the flu season, in collaboration with WHO Regional Office for Europe, in the report Flu News Europe.

The 2011 seasonal influenza immunisation campaigns have started across Europe. As in previous years ECDC is marking the start of the 2011-12 surveillance season in Week 40 with the publication of regular weekly updates of the main epidemiological and virological developments in the Weekly Influenza Surveillance Overview (WISO).
