Exposure to air pollution can worsen patient outcomes from COVID-19

Data from a new USC study shows a significant increase in the risk of severe outcomes for COVID-19 patients exposed to fine particles (PM2.5) and nitrogen dioxide (NO2), two common (and correlated) components of ambient air pollution in Southern California. Produced by ground and air traffic, industrial burning and other sources, these air pollutants can exacerbate the effects of the SARS-CoV-2 virus over both the short and long term.
