Demoustication operation after a first case detected in the Var – Liberation

Breaking News: First Indigenous Chikungunya Case Detected in La Crau, France

The Regional Health Agency of Provence-Alpes-Côte d’Azur has sounded the alarm following the detection of an indigenous chikungunya case in La Crau, Var. Immediate measures are being implemented to prevent the spread of the virus, which is transmitted by the tiger mosquito.

Rare Indigenous Case Highlights Precision Measures

Until now, all identified chikungunya cases in mainland France originated from contamination outside the territory, predominantly in Réunion Island. Indigenous cases, where individuals contract the virus within France without recent travel history, are exceedingly rare. The last recorded indigenous case in metropolitan France was in Île-de-France in 2024, with none reported in 2023.

The Agence Régionale de Santé (ARS) has conducted demoustication efforts in La Crau to eliminate larval breeding sites and adult mosquitoes. These efforts focus on both public roads and private gardens surrounding the affected area. Additionally, health authorities will carry out door-to-door to identify anyone with symptoms.

Chikungunya’s Global Impact and Spread Dynamics

The chikungunya epidemic has primarily affected the Indian Ocean island of Réunion, claiming 23 lives and reportedly infecting 200,000 people since January. Although the epidemic is declining in Réunion, it continues to gain momentum in Mayotte, with 746 reported cases so far this year.

The warmer temperatures currently in France are enhancing the activity of tiger mosquitoes, which also transmit dengue and zika viruses. In 2024, 83 aboriginal dengue cases were identified in mainland France across Provence-Alpes-Côte d’Azur, Occitanie, and Auvergne-Rhône-Alpes regions. The tiger mosquito, first detected in mainland France in 2004, is continuing its rapid expansion, now present in 81 departments, or 84% of the metropolitan departments.

Preventive Measures and Future Implications

Recent studies suggest that dengue and chikungunya could become endemic in Europe due to global warming, urbanization, and increased travel. To combat the spread, authorities released thousands of sterile tiger mosquitoes in Brive-la-Gaillarde, Corrèze, using a technique borrowed from agriculture to neutralize mosquito populations.

Experts advise vigilance and regular inspection of breeding sites. Effective personal protection includes wearing long sleeves and pants when outdoors, using mosquito repellent, and installing screens on windows and doors.
