Key Points

• In Guadeloupe, the spread of the virus continues to intensify across the archipelago and is particularly active in the municipalities of Saint-François and Trois-Rivières. Emergency room visits for dengue syndrome are on the rise.

• In Martinique, the spread of the dengue virus is intensifying across the entire territory, and hospital indicators—particularly emergency room visits for dengue syndrome—are on the rise. The DENV-2 serotype has been identified in the majority of cases investigated in Martinique and Guadeloupe.

• In Saint Martin: the epidemiological situation is calm, but it should be monitored closely.

• In Saint-Barthélemy: the situation is evolving on the island, with an increase in the number of cases reported in recent weeks.

Following consultation with members of the Technical Committees for Dengue Monitoring (formerly CEMIE) on August 17, 2023, Santé publique France considers that Guadeloupe and Martinique are now in the epidemic phase (phase 4, level 1 of the PSAGE dengue system).
