Surveillance and immunisation are keys to protect Europe against seasonal influenzaArchived
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).
Factsheet about seasonal influenza
Influenza is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. It can cause mild to severe illness, and at times can lead to death. The best way to prevent flu is by getting a flu vaccine each year.
