The magnitude of human costs from heatwaves can be reduced if adequate emergency prevention, preparedness, response and recovery measures are implemented in a sustainable and timely manner.
WHO works with the health sector to strengthen governance, preparedness and response to heatwaves, by developing contingency plans that map the risks, vulnerable populations, available capacities and resources. These plans also include early warning systems and ensure vulnerable populations, such as those in health facilities, nursing homes and schools have adequate provision of cooling equipment.
As the health cluster lead for global emergencies, WHO works with partners to respond to:
- ensure appropriate food supplementation;
- restore primary care services, like immunization, child and maternal health, and mental health;
- assemble mobile health teams and outreach;
- conduct epidemic surveillance, early warning and response;
- call for emergency funding to support health action
Heatwaves
Heatwaves, or heat and hot weather that can last for several days, can have a significant impact on society, including a rise in heat-related deaths. Heatwaves are among the most dangerous of natural hazards, but rarely receive adequate attention because their death tolls and destruction are not always immediately obvious. From 1998-2017, more than 166 000 people died due to heatwaves, including more than 70 000 who died during the 2003 heatwave in Europe.
