Aedes aegypti is an important invasive mosquito species that could potentially have an impact on European public health. It is found throughout tropical and subtropical regions of America, Africa and Asia, as well as southeastern US, Indian Ocean Islands and northern Australia. This species was established in Europe in the beginning of the 20th century as far north as Brest and Odessa and has recently re-established in Madeira and around the Black Sea in southern Russia, Abkhazia and Georgia.
Aedes aegypti do not overwinter like Aedes albopictus but can utilise sheltered sites in a domestic setting, which provide protection against environmental conditions and numerous aquatic habitats suitable for oviposition. There are no reasons why this species could not become widely established in southern Europe, if it were re-introduced.
Aedes aegypti is the main vector of dengue virus and is involved in major dengue fever epidemics in the America, Southeast Asia and the Western Pacific. It was also responsible for the large epidemics of dengue in Greece in 1927-1928.
Aedes aegypti is also a vector of chikungunya e.g. in Kenya and the Comoros Islands. The species can be a highly effective vector of yellow fever virus - a disease found in West, Central and East Africa, where large severe epidemics have been recorded with tens of thousands of deaths and in South America.
