PLoS Med. 2018;15(7):e1002601. https://doi.org/10.1371/journal.pmed.1002601. Findings from this large study in southern California suggest that the AQI level “unhealthy for sensitive groups” was associated with emergency department visits for respiratory conditions the day following WFS exposure, compared to the AQI level “good” (OR 1.73; 95% CI 1.18–2.53). This effect was especially pronounced for very young children.
