Wildfires may be accelerating the spread of infectious disease by keeping US West residents indoors: Study
BRITISH COLUMBIA, OREGON, WASHINGTON, ALBERTA, WALES, JUN 18 – Wildfire smoke increases indoor crowding by up to 14%, raising risks of flu and COVID-19 spread as poor air quality drives people to stay inside, researchers report.
- In early June 2025, widespread wildfires in northern regions caused thick smoke and air quality warnings affecting local communities and events.
- The increased wildfire activity, including a 407 percent rise in fires between March and May 2025, led to concerns over health risks from smoke exposure.
- Officials urged residents to reduce outdoor time, seal homes against smoke, and use HEPA air scrubbers, which Lac La Ronge Indian Band deployed in public health centres.
- Cook-Searson said air scrubbers are very effective, and Henderson reported wildfire smoke increases risks for chronic diseases and adverse birth outcomes.
- These events highlight the need for public education, indoor air quality measures, and community preparedness to mitigate wildfire smoke’s long-term health effects.
