Forty-seven imported cases of malaria have been reported in Reunion Island since January 2026, already exceeding the total recorded for the entire year of 2025, which saw 35 cases. Santé Publique France (French Public Health Agency) notes a “regional resurgence” of malaria, against a backdrop of rising reports in several neighboring Indian Ocean countries. According to the surveillance bulletin updated on August 31, the Comoros and Madagascar are the primary sources of origin for the diagnosed individuals.
The number of cases recorded since the beginning of the year also surpasses the 46 cases registered in 2024. The French health agency further highlights the continued increase in imported cases that began in 2023, following the lifting of travel restrictions related to the Covid-19 pandemic.
Nine cases were recorded in August, a level described as a “notable increase” by Santé Publique France. While May, June, and July saw relatively low levels, the number of cases through April was generally higher than those observed during the same periods in previous years.
The majority of patients (94%) presented with “uncomplicated malaria.” However, the proportion of patients requiring intensive care or critical care services has increased, rising from 13% in 2025 to 24% in 2026.
The affected individuals are predominantly adult men, with a median age of 46. They were mainly returning from family trips to the Comoros and Madagascar. The Comoros alone accounts for 72% of the recorded cases (34 people). Another case was diagnosed following a return from Mayotte.
In 98% of cases where the parasite was identified, it was Plasmodium falciparum, the species responsible for the most severe forms of malaria that may require intensive care.
Prevention remains a critical point of vigilance. According to Santé Publique France, half of those diagnosed were aware of the malaria risk before departure, but only 20% had started chemoprophylaxis (preventive treatment) before their trip, and none had continued it for the entire duration of their stay.
