Dengue Cases Confirmed in France: Public Health Response Underway
Langon, France – Health authorities are actively responding to a localized outbreak of dengue fever in the Gironde department, with six indigenous cases-involving eleven individuals-confirmed as of August 12, 2025. The cases involve individuals infected within France who did not exhibit symptoms within fifteen days of being in a known contaminated area. This marks a notable development in monitoring and controlling the spread of this mosquito-borne illness.
Understanding Dengue Fever
Dengue fever, often called “tropical flu,” is exclusively transmitted to humans through the bite of the aedes albopictus mosquito, commonly known as the tiger mosquito [[2]]. The virus is carried by the mosquito and spread through its bite. Symptoms typically include high fever, severe muscle and joint pain, headache, fatigue, and rash.
Did You Know? Dengue fever is the fastest-growing mosquito-borne viral disease in the world, with incidence increasing 30-fold over the last 50 years.
Public Health Actions in Langon
To curb the spread of the virus, Altopicus, the entomological surveillance operator for the tiger mosquito in Gironde, is conducting targeted mosquito control operations in areas frequented by affected individuals in Langon. These efforts focus on eliminating both mosquito larvae and adult mosquitoes.
Residents in affected sectors have been notified via flyers delivered to their mailboxes. Those who haven’t received a flyer are not currently within the treatment zone. A door-to-door survey will be conducted by ARS Nouvelle-Aquitaine and Public Health France, in collaboration with the Langon town hall, to identify individuals experiencing dengue-like symptoms-fever over 38.5°C, muscle pain, headache, joint pain, or rash.
Hospitals, physicians, pharmacists, and medical laboratories are mobilizing to provide care, detect cases, and reinforce preventative measures. Authorities emphasize the critical importance of reporting any suspected cases to enable a swift and targeted response.
Protecting Yourself and Your Family
Mosquito Bite Prevention
Health officials recommend the following precautions to minimize the risk of mosquito bites:
- Install mosquito nets over cribs and beds.
- Wear covering, loose-fitting clothing.
- Use fans to deter mosquitoes.
In Langon, applying a skin repellent is advised, notably during morning and evening hours, after consulting with a pharmacist for appropriate product selection.
eliminating Mosquito Breeding Grounds
Preventing mosquito proliferation requires eliminating stagnant water sources where they breed. Simple weekly actions include:
- Emptying plant saucers and containers holding small amounts of water.
- Storing items that can collect rainwater away from exposure.
- Covering or sealing water storage containers with mosquito netting.
Pro Tip: Even a bottle cap filled with water can serve as a breeding ground for hundreds of mosquitoes.
ARS Nouvelle-Aquitaine actively monitors the tiger mosquito population and collaborates with communities to implement effective control measures. The annual “no Neighborhood for Mosquitoes” interaction campaign provides resources and guidance. A dedicated platform for municipalities is also available: Tiger mosquito-New Aquitaine environmental health.

What are your biggest concerns regarding the spread of mosquito-borne illnesses in your region? How can communities work together to mitigate these risks?
Dengue fever is a growing global health threat,driven by factors such as climate change,urbanization,and increased international travel. The Aedes albopictus mosquito,originally from Southeast Asia,has rapidly expanded its range in recent decades,establishing itself in many parts of Europe,including France. Effective vector control, public awareness campaigns, and the development of vaccines are crucial for mitigating the impact of this disease. The current outbreak in Langon serves as a reminder of the need for continued vigilance and proactive public health measures.
