WHO Releases New Guidance To Prevent Heat
The World Health Organization has released new guidance aimed at preventing heat-related illnesses at mass gatherings. The report suggests that most heat-related medical issues can be managed on-site with proper preparedness and risk assessment.
Why it matters
As climate change increases the frequency of extreme heat events, this guidance provides a framework for event organizers to protect public health and reduce strain on local medical services.
The organisation said on Wednesday in a statement that the guidance followed evidence showing that most heat-related illnesses at mass gatherings could be prevented or treated on site when timely risk assessment, preparedness and response measures are in place.
“A WHO evidence review covering studies published between 1980 and 2025 documented nearly 500,000 medical encounters at mass gatherings, including more than 22,000 heat-related illnesses.
“The review found that more than 90 per cent of patients can be treated at event venues when on-site medical systems are well organised, reducing pressure on local hospitals and ambulance services,” it said.
Dr Chikwe Ihekweazu, Executive Director, WHO Health Emergencies Programme said that extreme heat was an increasing threat to health, safety and operational continuity in mass gatherings.
