The Unexpected Connection Between Wildfires and Mold Infections

An unusual increase in mold infections among burn patients at a California hospital prompted an investigation into the source of these infections. Typically, when outbreaks occur, all patients have the same pathogen due to shared environmental conditions. However, in this case, each patient was infected with different types of mold, raising questions about their origin. The examination of hospital air filters revealed they were overwhelmed with wildfire smoke, suggesting that fungal spores could be entering the hospital environment from outdoor conditions, potentially endangering premature burn victims.
