Is it true that exposure to wildfire smoke causes respiratory illness in nearby populations?
Yes. A 2018 review reporting that systematic reviews find a positive association between wildfire smoke exposure and respiratory morbidity, plus several cohort and surveillance studies in specific regions, support the claim that wildfire smoke exposure causes respiratory illness in nearby populations; one Massachusetts event study found no large increase in emergency visits.
