The European Influenza Surveillance Network (EISN) is coordinated by ECDC. The network combines epidemiological and virological surveillance of influenza to provide decision makers and public health experts in EU/EEA Member States with the information required to better assess influenza activity in Europe and take appropriate action. Ultimately, EISN aims to contribute to reducing the burden of disease associated with influenza in Europe.
Virological surveillance activities are coordinated through the European Reference Laboratory Network for Human Influenza (ERLI-Net), a sub-network within EISN.
Weekly analysis of influenza surveillance is available in the Weekly Influenza Surveillance Overview (WISO) from week 40 to week 20. Between seasons, i.e. from week 21 to week 39, the WISO is published on a fortnightly basis.
The situation of influenza in the WHO European Region is available through Euroflu published by WHO Europe. For global information, see WHO influenza updates.
