Colorado Sees Asthma Surge from Southern Rockies Wildfire Smoke

The Colorado Department of Public Health and Environment (CDPHE) issued an alert this week on elevated respiratory illnesses tied to ongoing wildfires in the southern Rockies, including areas near Durango and Pagosa Springs. Smoke plumes have drifted across the region, pushing air quality indexes into the unhealthy range for sensitive groups. Initial reporting by CBS Colorado highlighted a 15% uptick in asthma-related emergency department visits in affected counties over the past seven days, echoing patterns from the 2012 fire season when odds of asthma hospitalizations rose by 7% per 10 µg/m³ increase in PM2.5 exposure.

Dr. David Beuther, a pulmonologist at National Jewish Health in Denver, explained that wildfire smoke's fine particulate matter penetrates deep into the lungs, triggering inflammation body-wide. "It irritates asthma and other lung diseases, but can cause broader effects like chest pain and rapid heartbeat," Beuther said in a recent Colorado Public Radio interview. Similarly, Dr. Fernando Holguin, a pulmonary expert at University of Colorado Anschutz Medical Campus, noted that smoke narrows airways, leading to shortness of breath and exacerbated conditions for smokers and those with preexisting illnesses. CDC data confirms immediate risks including wheezing, coughing and asthma attacks from such exposure.

Local context amplifies the threat at Colorado's high altitude, where reduced oxygen intake compounds smoke's fatigue-inducing effects, according to University of Colorado Boulder researchers. CDPHE recommends staying indoors with HEPA-filtered HVAC systems running, especially in mountain towns like Telluride and Creede bearing the brunt. Officials report over 20 active fires statewide as of early May 2026, with no containment dates in sight amid dry conditions.
