Key Points

Dengue

• Dengue activity is low throughout the country.

Chikungunya

• Since late January (Week 4), 2,065 cases of chikungunya have been laboratory-confirmed in French Guiana, including 30 in Week 40 (unconsolidated data). The virus is actively circulating in the territory:
• Western Coast: After several weeks of slowing virus circulation on the
  Western Coast and low emergency department activity due to chikungunya, the epidemic has ended, and the area has been in the post-epidemic phase since S38. However, cases continue to be diagnosed, so vigilance must be maintained, as a resurgence of the epidemic cannot be ruled out given the regional situation.
• Savanes: The number of visits to the CHK emergency department for suspected chikungunya was declining in Week 40, with the proportion of activity related to these visits also declining and falling below 6%. However, the epidemic continues in this sector.
• Cayenne Island: In Week 40, one active outbreak was being monitored in the area. Due to the lack of some laboratory data, the trend is difficult to interpret, and the number of cases is likely underestimated. Cayenne Island remains in the phase of epidemic outbreaks.
• Maroni: No new cases were biologically confirmed in Week 40 in this sector, which is in the sporadic transmission phase.
• Interior, Eastern Interior, and Oyapock: No new cases have been biologically confirmed in S40. These sectors are in the epidemiological surveillance phase.
