Heterogeneous case definitions used for the surveillance of influenza in Europe

Eur J Epidemiol. 2003;18(8):751-4. doi: 10.1023/a:1025337616327.


We reviewed the case definitions used by 21 influenza sentinel-based surveillance networks in Western Europe. Two clinical syndromes were used with a wide range of case definitions that nevertheless shared common criteria. Although there is currently no international consensus, efforts are being undertaken to standardise influenza case definitions in Europe.
