Wildfire Smoke Worsens Coronavirus Risk, Putting Firefighters In Extra Danger, Luke Montrose Apr 2020

Wildfire Smoke Worsens Coronavirus Risk, Putting Firefighters In Extra Danger, Luke Montrose

Public and Population Health Faculty Publications and Presentations

As summer approaches, two forces of nature are on a collision course, and wildland firefighters will be caught in the middle.

New research suggests that the smoke firefighters breathe on the front lines of wildfires is putting them at greater risk from the new coronavirus, with potentially lethal effects.

At the same time, firefighting conditions make precautions such as social distancing and hand-washing difficult, increasing the chance that, once the virus enters a fire camp, it could quickly spread.

As an environmental toxicologist, I have spent the last decade expanding our understanding of how wood smoke exposure impacts human health. …
