Increasing notification of cases

In August 2007, a Chikungunya outbreak was declared for the first time in Europe. This outbreak was the first one documented in a temperate climate country. Two hunderd human cases were recorded in two small towns of Italy. The vector of the CHIKV during this outbreak was the Aedes albopictus, commonly known as the Asian tiger mosquito, which appeared to have become abundant in the area. The virus was apparently introduced by a traveller who came back from south-west India where the virus was circulating (Source: ECDC).

In July 2011, the latest WNV season started in Europe. By the end of November 2011, 93 confirmed human cases of West Nile fever had been reported in the European Union: 69 cases in Greece, 14 in Italy and 10 in Romania. In the neighbouring countries, 189 cases in total had been reported (Source: Kalaycioglu et al., Eurosurveillance 2012).
