Spain: Surveillance and control of heatwave effects 2022 Madrid

This Heat wave action plan establishes a Surveillance and Information System that considers temperatures posing health risks in the geographical area of the Community of Madrid. Based on existing scientific literature, a maximum threshold of 36.5°C was set, beyond which there is a significant increase in mortality, prompting the activation of health protection measures. From June 1 to September 15, daily (excluding weekends and holidays) risk/alert levels for heat are communicated to the general population, healthcare and social professionals, and institutions responsible for socio-sanitary care of vulnerable groups. This ensures readiness well in advance of potential heatwaves and strengthens intervention mechanisms. A crucial aspect of the plan involves monitoring morbidity and mortality throughout the campaign to compare observed data with expected trends, thereby detecting any unusual increases early on.
