[Aedes albopictus in Italy: an underestimated health problem].

Since 1990, Ae. albopictus has spread in 9 regions and 30 provinces of the country. This species was introduced in Italy in shipments of scrap tires form the USA. In Italy, Ae. albopictus is the major biting pest throughout much of its range and, although there is no evidence that this mosquito is the vector of human disease in the country, the species might be involved in the transmission of some arboviruses which have been reported in the Mediterranean Basin. Aim of this paper is to provide an update on the distribution of Ae. albopictus in Italy and to renew the interest in a problem frequently underestimated. Public health implications after a ten-year presence of the species are also discussed.
