Chikungunya Cases Rise in Bourgogne-Franche-Comté, Linked to Climate Change
Health authorities in Bourgogne-Franche-Comté are reporting an increase in chikungunya cases, prompting public health measures and raising concerns about the expanding range of tropical diseases. The Regional Health Agency (ARS) has activated a dedicated information hotline – 0805 200 550 – available seven days a week from 8:30 AM to 12:00 PM and from 1:30 PM to 5:00 PM.
The surge is attributed to the northward migration of the Aedes albopictus mosquito, the primary vector for chikungunya, driven by climate change. Bruno Maèstry, a regional health official, explained, “The mosquito, historically found in tropical and intertropical climates, is now establishing itself in regions like ours. Changing conditions allow it to survive and reproduce.”
Pharmacists are observing a corresponding increase in demand for mosquito repellents. Benoît Payant, owner of the pharmacy “Au Port du Canal” in Port du Canal, noted a significant rise in insecticide sales.He recommends a multi-pronged approach to protection, emphasizing the effectiveness of repellents applied directly to the skin. “Combining methods is key,” Payant advises.”Diffusing essential oils, using citronella, and employing mosquito traps are all helpful, but a mosquito net remains the most reliable mechanical barrier.”
These mosquito control operations are conducted during nighttime hours, and residents are informed in advance. The ARS is also collaborating with local municipalities – including Dijon, Besançon, and Chalon-sur-Saône – to implement enhanced surveillance and mosquito control programs. The Aedes albopictus mosquito is identifiable by its distinctive black and white markings and is an aggressive daytime biter.
chikungunya is characterized by fever and severe joint pain, which can be debilitating and long-lasting. While typically not fatal, the illness can cause significant morbidity. The ARS urges residents to eliminate standing water around their properties – in flower pots,gutters,and tires – to reduce mosquito breeding sites.The hotline provides information on symptoms, prevention, and available resources.
