Outbreak Response

As soon as the 1st cases arrived, preventive measures and vector control measures had been put in place on the island in order to limit the spread of the disease on the territory.

Although the number of cases has stabilized for several weeks, the Rift Valley fever virus still circulates in some communes of the island. Therefore, the health authorities reiterate the importance of continuing to respect preventive measures to prevent infection and prevent an epidemic recovery when the rainy season returns.
