In the Mediterranean basin, West Nile virus (WNV) causes sporadic outbreaks, which usually affect a low number of humans and animals, after which long periods without virus circulation occur. An hypothesis is that the virus can remain silent, circulating in a sylvatic enzootic bird-mosquito cycle and only under appropriate conditions causing new outbreaks in humans and horses.
During the late summer 2008 a large epidemic of West Nile virus occurred in North-East Italy involving an area of more than 7,000 Kmsq in 3 Regions (Lombardia, Veneto, Emilia-Romagna). This was the largest epidemic ever recorded in the country. Following the first evidence in equine and birds an active entomological surveillance plan was started by the Emilia-Romagna Surveillance Group on Vectorial Disease.
