• At the regional level, analysis of emergency department visits for the composite health indicator iCanicule during the heat wave shows:
  • a stable daily number of emergency department visits throughout the episode and a situation comparable to that observed during the reference period (July 23–29), for all age groups as well as for those aged 75 and older;
  • a stable number of heat-related hospitalizations following visits to the emergency department over the same timeframe;
  • very low activity at the SOS Médecins chapter in Ajaccio.
