Public health efforts to manage mosquito populations and vector-borne diseases have intensified across different regions. In France and Senegal, authorities have launched specific control measures, including insecticide spraying in Maine-et-Loire to address dengue fever alerts and larval control campaigns in Touba, Senegal, to prevent malaria.

Expanding on regional cooperation, France, Germany, and Switzerland have initiated ‘Tiger 2.0’, a three-year cross-border program. This initiative targets the tiger mosquito in the Upper Rhine region, which has expanded due to climate change. The project focuses on scientific research, public awareness, and simulating epidemic outbreak responses to combat viruses such as dengue, chikungunya, and Zika.

In France, the tiger mosquito (Aedes albopictus) has established a permanent presence in 83 departments, spreading from the Mediterranean coast to northern and western regions. Health authorities, including Santé publique France, are monitoring the species due to the risk of local outbreaks of dengue, chikungunya, and Zika. Because the mosquito is an urban species that typically stays within a 150-meter radius of its birth site, officials emphasize that local community action—such as eliminating standing water—is essential to reducing regional risks.
