Already present in Grand Est in several neighboring departments, the tiger mosquito has, since 2020, been the subject of monitoring in Haute-Marne, in particular in the municipalities of Saint-Dizier, Chaumont, Langres and Le Montsaugeonnais in which traps were installed.
Following the detection of its presence in Langres in August 2024, as part of monitoring the network of traps and the receipt of a positive citizen report, the Regional Health Agency (ARS) now classifies the department of Haute-Marne in an area colonized by the tiger mosquito. The ARS Grand Est carried out a field investigation to verify its presence with the implementation of preventive actions as well as measures to eliminate larval breeding sites.
The results of this investigation suggest a long-term establishment and development of the species in the commune of Langres. It is therefore considered to be colonized, thus leading to the classification of the entire department of Haute-Marne as a colonized zone. There are now five departments in the Grand Est region which are considered to be colonized by the tiger mosquito: Bas-Rhin, Haut-Rhin, Meurthe-et-Moselle, Moselle and Haute-Marne.
“The tiger mosquito is a potential vector of dengue, chikungunya and Zika viruses, hence the importance of fighting against its presence”indicates a press release from the ARS.
