Key Points

• In Guadeloupe, the virus is spreading throughout the archipelago, with several sporadic cases, including three reported in Marie-Galante. Three outbreaks have been identified in Trois-Rivières, Gosier, and Saint-François.

• In Martinique, the spread of the dengue virus continues, with sporadic cases now reported in three new municipalities in central and northern Martinique.

• Several dengue cases have been imported into mainland France since the start of the resurgence in cases (November 2022 for Guadeloupe and January 2023 for Martinique). The DENV-2 serotype has been identified in the majority of investigated cases.

• In Saint Martin, the epidemiological situation is stable; it is evolving in Saint Barthélemy, where particular vigilance is required.
