Public Health France reported on May 7, 2025, that twelve deaths related to chikungunya have occurred in La Réunion since the beginning of the year.

The recent update noted three additional deaths attributed to the viral infection, which primarily affected individuals over the age of 70 with pre-existing health conditions.

These conditions were largely chronic diseases.

From April 28 to May 4, there were 3,079 confirmed cases of chikungunya, a decrease compared to the 3,601 cases reported in the prior week.

In addition, 28 other deaths, including that of an infant, are under investigation to determine any potential links to the disease.

The public health agency indicated that the epidemic has shown signs of a decrease since late April.

However, it remains active, with variations across different areas of the region.

Emergency services recorded 250 visits related to chikungunya during the latest week, down from 332 the previous week, representing a 25% decrease.

Moreover, consultations in general medicine also fell to 14,030 from 23,140 in the preceding week.

Precautions are advised as the decline in cases may be affected by the national holiday on May 1 and the onset of school vacations, leading officials to interpret these trends with caution.

Overall, La Réunion has confirmed a total of 47,500 cases of chikungunya in 2025. The current outbreak began in August 2024, with a sharp increase in cases noted from March 2025 onward.

The last major chikungunya outbreak on the island occurred between 2005 and 2006, affecting approximately 260,000 individuals and resulting in over 200 deaths.

The disease, often referred to as the 'bent man’s disease,' is characterized by severe joint pain, headaches, and high fevers.
