Leptospirosis Cases Rise in Réunion Island, One Death Reported
Health officials in Réunion Island are reporting a concerning increase in leptospirosis cases, with 25 confirmed infections and one fatality recorded since the beginning of the year. The rise in cases is linked to the current summer season, which creates favorable conditions for the bacteria to thrive, and is prompting public health warnings.
Leptospirosis is a bacterial infection transmitted through the urine of rodents. The infection can enter the body through open wounds or even minor cuts, making individuals who work outdoors or participate in water activities particularly vulnerable. This disease can pose a significant health risk, and awareness of preventative measures is crucial.
“I wasn’t aware of this problem for pools and streams, and I admit it’s a bit scary,” said one resident, reflecting a growing concern among the population. “There have been cases of illness and even death.”
According to the Regional Health Agency, farmers, gardeners, and those who swim in freshwater sources are all at risk. The recent increase has prompted officials to emphasize the importance of taking precautions when exposed to potentially contaminated environments.
As of January 1, 2026, the Regional Health Agency has confirmed 25 cases, resulting in seven hospitalizations and one death. The majority of cases are linked to agricultural work and livestock farming, but infections have been reported across all municipalities on the island.
A similar situation was observed in the first half of 2025, with 114 cases reported across Réunion Island. The majority of those affected were adult males, and a significant number required hospital care, including intensive care in a third of the cases. Public health data indicates a comparable incidence rate between the south and east sectors of the island.
Health officials are urging residents to be vigilant, particularly during the rainy season, and to grab necessary precautions to protect themselves from infection. The findings underscore the ongoing public health challenges posed by infectious diseases in tropical environments.
