This mosquito is basically urban: it spreads in places inhabited by man. This insect is mostly harmless, but it can still be a vector of serious tropical diseases such as dengue and chikungunya.
"It is virtually impossible to get rid of it after being installed in a community or department"observe, fatalistic, authorities. Tiger mosquito, a species capable of transmitting diseases like dengue, chikungunya and zika, continues to grow in France: now it is implanted in more than half of the department, including Paris, says Friday the Ministry of Health. April 26th.
The insects were so "permanently installed" in 51 departments in 2018 versus 42 a year earlier, the Ministry, which annually updates its implementation map since its inception in mainland France in 2004.
The capital, still saved, is now part of the mosquito area "implanted and active"as well as Seine-Saint-Denis, Seine-et-Marne and Essonne. Of the eight Ile-de-France departments, only Val-d'Oise is unaffected by the presence of this insect that was "sporadically found" in Yvelines.
Other new tiger mining countries are Charente-Maritime, Côte-d'Or, Or, Loire, Nièvre and Puy-de-Dôme.
Native to Asia, tiger mosquito, or Aedes albopictus, settled in Alpes-Maritimes in 2004 and "quickly developed" Since then, the ministry recalls the data used by public mosquito control operators to monitor its implantation. He likes places inhabited by man, which explains his development in cities.
Global warming and the multiplication of international exchanges help to spread the territory of the insects and the viruses they carry, emphasize the experts.
The mere presence of mosquitoes does not necessarily lead to the occurrence of diseases in which it is a vector. Transmission is carried out when a "healthy" tiger mosquito bites a contaminated person while away from metropolitan France. The insect then becomes the carrier of the virus and can pass it on to a healthy person who did not live outside the territory.
The first cases of autochthonous contamination occurred in metropolitan France in 2010 with two cases of dengue in Alpes-Maritimes and two cases of chikungunya in Var.
Since then, the French authorities have recorded a total of 22 dengue cases and 31 chikungunya cases. In 2017 and 2018, they also observed 29 cases of the West Nile virus, which is transmitted by a common mosquito in the northern hemisphere. Culex pipiens,
