Since January 2026, 32 cases of leptospirosis have been recorded in French Polynesia, of which approximately 20 required hospitalization and nine required intensive care. One death has also been reported. Health authorities are urging increased vigilance, as the rainy season promotes the spread of this bacterial infection.
Leptospirosis is transmitted through contact with water or soil contaminated by animal urine, particularly that of rodents. Agricultural activities, outdoor work, and travel in flooded areas are identified as high-risk situations. Exposed professionals are advised to wear protective equipment and limit contact with stagnant water.
Symptoms similar to the flu
The disease typically begins with nonspecific symptoms, such as high fever, muscle aches, and extreme fatigue. Authorities remind the public that, in the absence of a flu epidemic or active dengue transmission, any high fever occurring after exposure to a humid environment should prompt immediate medical attention.
In 2025, 175 cases were recorded in the region. Health services emphasize the importance of early treatment to prevent severe illness. They also recommend disinfecting any wounds, controlling rodent populations, and adhering to preventative measures to limit transmission.
