Aedes albopictus, known as the tiger mosquito, has been installed for many years in ultra-marine territories, especially in the Indian Ocean where a dengue epidemic is raging on Reunion Island for the 3rd consecutive year.
In mainland France, it has grown significantly and continuously since 2004 and is now present in 58 departments, including Saône-et-Loire since 2014, Nièvre and Côte-d’Or since 2018. It could very well affect soon the neighboring Jura department.

The capacity of the tiger mosquito to be a vector of chikungunya, dengue or the zika virus, makes it a priority surveillance target for health authorities and their partners during its period of activity in mainland France: from May 1 to November 30. The objective of this reinforced surveillance is twofold: it is both a question of slowing the progression of the establishment of the tiger mosquito and of limiting the risk of importation and circulation of the viruses of which it can be the vector in mainland France. .
