Reinforced surveillance of the tiger mosquito is put in place by the authorities from May 1 until November 30. Present and active in Paris, the tiger mosquito can, under certain specific conditions, be a vector of diseases such as dengue fever, chikungunya or the Zika virus.
The tiger mosquito (Aedes albopictus), native to Southeast Asia, is a particularly harmful invasive species of mosquito that has been present in France since 2004. It is a small mosquito (5 mm), active during the day, with an aggressive peak in dawn and dusk. It has black and white stripes on its body and legs.
Where do we find it?
To date, the tiger mosquito is declared declared declared and active in a majority of French departments, including Paris, Seine-et-Marne, Yvelines, Essonne, Hauts-de-Seine, Seine-Saint-Denis , Val-d’Oise and Val-de-Marne.
There is no progression of the colonization of the tiger mosquito in Paris, but the whole of the Parisian territory remains vigilant.
What health risks ?
The tiger mosquito can be a vector of certain diseases such as dengue fever, chikungunya or the Zika virus. To transmit one of these three diseases, it must have previously bitten a sick person. Although these diseases are mainly prevalent in tropical areas, people returning from travel in areas where these diseases circulate (Africa, West Indies, South America, Southeast Asia, Indian Ocean) can during the few days of contagiousness contaminate a Mosquito that bites them.
The mosquito then becomes a carrier of the virus and can transmit it locally by biting new people. Local (indigenous) chains of transmission are then formed and an epidemic eventually develops.
Note that the tiger mosquito does not transmit Covid-19.
