Key Points

• The heat wave began on June 15 and affected 71 departments under an orange alert and 14 under a red alert. It ended on June 22. This report focuses on the end of the heat wave, which affected the Auvergne-Rhône-Alpes and Bourgogne-Franche-Comté regions.

• Analysis of emergency care utilization shows an increase in the composite health indicator tracked as part of the heatwave and health alert system (iCanicule: hyperthermia and heatstroke, dehydration, and hyponatremia) from the start of the heatwave through June 18, with the exception of hospitalizations, which peaked on June 21. The levels observed in recent days correspond to those prior to the heat wave.

• The observed health impacts underscore once again that heat is a health risk. It is important to implement the preventive measures recommended by the national heat wave management plan.
