Health issues among residents with smoke damage

Scientists surveyed 579 residents who reported homes smelling like smoke or chemicals one week after the 2021 Marshall Fire. Of those, 55% had at least one health symptom six months later. Of the 389 who responded to a later survey, 33% had at least one health symptom.

Bar charts show health symptoms continuing a year after the fire, particularly cough, itchy eyes, sneezing, sore throat and headache.
