To date, three departments of the Grand Est have been colonized by the mosquito tigerwe learn from the Regional Health Agency (ARS), which published an update on the subject in early June.

These are Bas-Rhin, Haut-Rhin and Meurthe-et-Moselle.

Established in the Grand Est since 2015

In the Grand Est, the tiger mosquito spread in the Bas-Rhin in 2015, then in 2016 in the Haut-Rhin and finally in Meurthe-et-Moselle since 2021.

This last department has only one colonized municipality: Nancy, declared as such on October 1, 2021, after the tiger mosquito was detected in several districts.

30 colonized municipalities

In total, on the scale of the three departments, the ARS counts 30 colonized municipalities.

Among them, 10 were classified as such in 2021 alone.

The list of colonized municipalities is updated several times a year on the ANSES website.

Potential carrier of chikungunya, dengue or zika

As the ARS reminds us, this mosquito can be a vector of viruses of the chikungunyaof the dengue fever and zika.

“In fact, the mosquito becomes infected by taking the virus from the blood of a sick person infected (following a trip to a tropical zone) during a bite and then, during another bite, transmits the virus to a new person”, details the agency.

“Once deployed in an area, it is very difficult to eliminate it,” she says.
