Aedes albopictus, the Asian tiger mosquito, can transmit several disease pathogens such as West Nile virus and Chikungunya virus. In the summer of 2007, the tiger mosquito was responsible for the first chikungunya fever outbreak in continental Europe. In collaboration with ECDC, a team of entomologists evaluated data from dozens of European countries and developed a series of detailed maps that show the current (and assumed future) distribution of Aedes albopictus in Europe.
