Key Points

Dengue, Chikungunya, and Zika

• In Corsica, since the start of enhanced surveillance (May 1), 2 imported cases of dengue and 3 imported cases of chikungunya have been confirmed (no new cases compared to last week).

• While the chikungunya outbreaks in Réunion and the dengue outbreaks in the French West Indies continue to impact surveillance in mainland France, the decline in viral circulation in these territories—particularly in Réunion—is reflected in the number of imported cases reported in recent days.

Heat Wave

• No heat wave currently underway.

• Activity at emergency departments and the SOS Médecins association is stable, slightly higher than in previous years.

Pollen exposure, which may pose an allergy risk

• In Corsica, the pollen index, established by Atmo France and accredited air quality monitoring associations, remains at a high level, primarily due to grass pollen.

• Allergy-related activity at SOS Médecins associations is decreasing and remains at a level similar to that observed in previous years during the same period.
