Key Points

• The first heat wave of 2018 is affecting several departments. Not all regions are being impacted equally by this heat wave. Some regions are experiencing longer-lasting effects, particularly the Auvergne-Rhône-Alpes region.

• A new, longer-lasting, and more widespread heat wave is expected this week.

• A significant increase in emergency room visits and SOS Médecins consultations for heat-related illnesses (HRI) has been observed, particularly on July 26 and 27. These increases are expected during a heat wave.

• Indicators have returned to normal across all regions except Auvergne-Rhône-Alpes, in line with the alert level.

• The trend in healthcare utilization for heat-related illnesses indicates that extreme heat remains a significant health risk.

• The implementation of preventive measures is all the more justified given that another heatwave cannot be ruled out in the coming days.
