Urgent: Mosquito-Borne Virus Cases – Chikungunya, Dengue, Zika & West Nile – Expanding Across France
Paris, France – September 22, 2025 – A concerning surge in locally acquired cases of Chikungunya, Dengue, Zika, and West Nile Virus is prompting heightened public health alerts across France. New data released today reveals a significant expansion of affected regions, marking a worrying trend as the autumn season begins. This is a breaking news situation, and we’re committed to bringing you the latest updates as they unfold. This article is optimized for Google News and SEO to ensure rapid dissemination of critical information.
Local Transmission: A Widening Geographic Footprint
As of today, September 22, 2025, authorities have identified 76 homes across France experiencing vector transmission of Chikungunya and Dengue. Specifically, 570 cases of Chikungunya have been linked to 65 households (ranging from 1 to 103 cases per household, with 21 homes now considered contained), while 24 Dengue cases have been traced to 11 homes (1 to 5 cases per household, with 8 homes contained). Eight isolated Chikungunya cases and one isolated Dengue case remain under investigation, with the precise location of infection still undetermined.
The virus isn’t staying put. While previously concentrated in regions like Auvergne-Rhône-Alpes, Corsica, Ile de France, Occitanie, and Provence-Alpes-Côte d’Azur, local transmission has now been confirmed for the first time this year in Burgundy-Franche Comté, Center-Val de Loire, Grand Est, and Nouvelle-Aquitaine. This expansion signals a broader challenge for public health officials.

Imported Cases & The Zika Factor
Beyond local transmission, a substantial number of cases have been imported by travelers. 993 cases of Chikungunya, 939 cases of Dengue, and 10 cases of Zika have been reported in individuals who contracted the viruses abroad. This underscores the importance of travel health precautions and awareness. Zika, while less prevalent in these imported cases, remains a concern due to its potential impact on pregnant women and newborns.
Evergreen Insight: Mosquito-borne diseases are increasingly prevalent globally due to climate change and increased international travel. The Aedes aegypti and Aedes albopictus mosquitoes, primary vectors for these viruses, are expanding their ranges, making previously unaffected areas vulnerable. Understanding your risk based on travel history and local conditions is crucial.
West Nile Virus: A New Concern in Ile-de-France
Adding to the complexity, 36 human cases of West Nile Virus acquired through local vector transmission have been identified in 11 departments. The Provence-Alpes-Côte d’Azur and Occitanie regions continue to be affected, but the virus has now spread to Ile-de-France and Auvergne-Rhône-Alpes for the first time. West Nile Virus can cause a range of symptoms, from mild flu-like illness to severe neurological complications.

Protecting Yourself: Prevention is Key
French health authorities are urging residents to take preventative measures to minimize their risk of infection. These include:
- Eliminating standing water: Mosquitoes breed in stagnant water, so regularly empty containers like flower pots, tires, and birdbaths.
- Using mosquito repellent: Apply repellent containing DEET, picaridin, or IR3535 to exposed skin and clothing.
- Wearing protective clothing: Cover up with long sleeves and pants, especially during peak mosquito activity hours (dawn and dusk).
- Installing mosquito nets: Use mosquito nets over beds, especially for vulnerable individuals like infants and pregnant women.
Expert Advice: Dr. Isabelle Dubois, a leading epidemiologist at the Pasteur Institute, emphasizes, “The key to controlling these outbreaks is community involvement. Everyone has a role to play in eliminating mosquito breeding sites and protecting themselves from bites.”
