Key points

Guadeloupe and Martinique

• In Phase 4, Level 1 of the PSAGE^* dengue alert system: confirmed epidemic.

However, vigilance must be maintained and efforts to combat the Aedes aegypti mosquito should even be stepped up, particularly in areas with high tourist potential: during May 2024, 67% of dengue cases imported into mainland France were linked to travel to Guadeloupe or Martinique.

Saint Barthélemy and Saint Martin

• Saint-Barthélemy and Saint-Martin are in Phase 1 of the PSAGE*: sporadic cases and isolated outbreaks with no epidemiological link(s).

Dengue circulation remains at low levels; the situation has returned to normal since mid-March 2024.

* Surveillance, Alert, and Epidemic Management Programs.
