WHO Warns: Wildfire Smoke Poses Growing Health Risks
24 Jul
Summary
- Wildfires are increasing in frequency and intensity across Europe.
- Smoke from fires travels hundreds of kilometers, harming health.
- WHO urges governments to issue timely wildfire and air-quality alerts.
Wildfires are becoming a significant health concern across Europe, according to the World Health Organization (WHO). As of July 22, 2026, a notable increase in fire frequency and intensity has been observed, with Portugal and Spain experiencing a 100% rise in wildfires compared to the same period in 2025.
The health implications of these fires extend far beyond the immediate vicinity. Smoke plumes can travel hundreds of kilometers, degrading air quality and releasing harmful pollutants such as PM2.5 and NO2. These pollutants can worsen existing heart and respiratory conditions and negatively impact mental well-being.
WHO Europe chief Hans Henri P. Kluge emphasized the need for preparedness, stating that climate change is driving more frequent and intense wildfires. He called upon governments to provide timely alerts for wildfires, weather, and air quality, alongside clear health advice and accessible emergency care.
