Key Points 

Extreme heat, heat wave

• In S22, heat-related emergency room visits and SOS Médecins medical interventions increased significantly in the Provence-Alpes-Côte d’Azur region: compared to S20, the number of visits and the share of emergency department activity for the iCanicule indicator (hyperthermia/heatstroke, dehydration, and hyponatremia) tripled. A slight increase in fainting episodes was also observed.

Dengue, Chikungunya, and Zika

• Since the start of enhanced surveillance (May 1), 21 imported cases have been identified in the region: 6 of chikungunya (+2 compared to last week) and 15 of dengue (+4).

West Nile virus infections

• No locally acquired cases have been detected in the region, or more broadly in mainland France, since the start of enhanced surveillance (May 1).

Pollen and Allergies

• Pollen exposure was at a high level in the Provence-Alpes-Côte d’Azur region. Allergy-related activity at SOS Médecins has stabilized at a level typical for the season.

Mortality

• No excess mortality was observed.
