On April 19, 2025, Santé publique France (SPF) and Guadeloupe's regional health agency (ARS) confirmed a case of Chikungunya in the region. The patient, who had recently returned from a trip to the island of La Réunion, resides in Guadeloupe. This discovery comes as the island continues to battle an ongoing Dengue epidemic, which began in November 2024.
Health authorities acted swiftly to address the situation. An environmental investigation was launched around the patient’s home to evaluate the presence of mosquitoes, eliminate breeding sites, and remind residents of essential prevention measures. Given that infected mosquitoes transmit both Chikungunya and Dengue, this proactive approach is crucial to limiting the risk of secondary cases in the community.
A Double Threat: Dengue and Chikungunya
While the Chikungunya case in Guadeloupe is currently isolated, the ongoing Dengue epidemic remains a concern. Between April 7 and April 13, about 200 suspected cases of Dengue were reported during local medical consultations, indicating that transmission remains active.
These mosquito-borne diseases share many similarities, including their symptoms and primary vector, the Aedes aegypti mosquito. Symptoms can include fever, joint and muscle pain, rashes, and fatigue. Residents must remain vigilant and adopt preventive measures to curb the spread of both illnesses.
How You Can Help Prevent the Spread of Mosquito-Borne Diseases
The fight against Chikungunya and Dengue requires collective community action. ARS has reinforced the importance of prevention and protection to minimize mosquito populations and reduce the risks of infection. Here are the key measures everyone should follow:
- Eliminate Mosquito Breeding Sites
Mosquitoes lay eggs in stagnant water, so removing any standing water around your home is essential. This includes:
- Checking and cleaning water tanks or cisterns.
- Disposing of items that can collect water, such as old tires, buckets, and other debris.
- Emptying or removing saucers under plant pots and containers.
- Regularly emptying vases, rainwater gutters, and anything else holding water.
- Use Personal Protection
Protect yourself and your family by taking these steps:
- Wear long, loose-fitting clothing, especially during the early morning and late afternoon when mosquitoes are most active.
- Apply insect repellents, ensuring guidelines are followed, particularly for children and pregnant women.
- Use mosquito nets at night—for sleeping adults, children, and over cradles for newborns.
- Cover Water Supplies
If you store water for household use, ensure these containers are tightly covered with a mosquito-proof net or lid. - Be Mindful of Symptoms
If you or someone in your household has recently traveled, particularly to La Réunion, and starts experiencing fever, joint pain, rashes, or itching within three weeks of returning, consult a healthcare professional immediately. Early detection can prevent complications and help reduce community spread.
The Role of the Community
Tackling mosquito-borne diseases is a shared responsibility. By maintaining clean surroundings, protecting ourselves from bites, and staying informed, we can collectively reduce the risk of Chikungunya and Dengue in our communities.
Health authorities will continue their monitoring efforts and provide updates on any changes in the situation. However, the most significant impact comes from community efforts. Together, we can control mosquito populations and minimize the risks posed by these diseases.
Stay safe, take action, and encourage your friends and neighbors to do the same. Prevention today can save lives tomorrow. Let's work together for a healthier Guadeloupe!
