The Global Influenza Surveillance and Response System (GISRS), led by WHO, is used for the international virological and epidemiological surveillance of human influenza.
The clinical surveillance of influenza in the European Influenza Surveillance Network (EISN) is generally based on reports made by sentinel general practitioners. Some of the sentinel surveillance systems also include paediatricians and physicians with other specialisations. The physicians usually represent 1-5% of physicians working in the country or region.
