Chikungunya

Since late January (Week 04), 2,202 cases of chikungunya have been laboratory-confirmed in French Guiana, including 10 in Week 45 (unconsolidated data). Although the number of cases has dropped sharply in recent weeks, the virus remains active in the territory:

• Western Coast: The chikungunya outbreak has ended in this sector, which has been in the post-outbreak phase since S38. The virus has been circulating at very low levels there for several weeks.
• Savanas: The number of visits to the CHK emergency department for suspected chikungunya remained stable at a moderate level after several weeks of decline. Chikungunya accounted for less than 4% of emergency department activity in Week 45. The outbreak continues in this sector.
• Cayenne Island: In Week 45, one active outbreak was being monitored in the area. The number of confirmed cases remained low, as did activity in the CHC emergency department. Cayenne Island is in the outbreak phase.
• Maroni: No new cases were biologically confirmed in this sector, which is in the sporadic transmission phase.
• Interior, Eastern Interior, and Oyapock: No new cases have been biologically confirmed. These sectors are in the epidemiological surveillance phase.
