Although in recent years localized outbreaks of autochthonous (locally acquired) dengue and chikungunya have mainly occurred in northern and central Italy, the potential for new outbreaks extends to many other areas of the country. These areas are characterized by a significant presence of the mosquito vector, commonly known as the “tiger mosquito” (scientific name Aedes albopictus), along with favorable climatic conditions.According to the study coordinated by Fondazione Bruno Kessler and the National Institute for Health in partnership with the Ministry of Health and Regions/Autonomous Provinces, coastal areas and urban suburbs across the Italian peninsula are particularly suitable environments for the development of such outbreaks.
