This episode discusses two MMWR reports. First, the average percentage of emergency department visits potentially associated with fire and smoke inhalation increased eightfold to 0.5% during the first 6 days of the 2025 Los Angeles County wildfires. Next, firefighters had higher concentrations of PFAS - a group of chemicals linked to cancer and other health effects - in their blood 1 month after responding to the 2023 Maui wildfires than other responder groups.
