In this study, we examined over 3 million SARS-CoV-2 infections and about 50,000 COVID-19 deaths in California from February 2020 to February 2021 to evaluate risks associated with long-term neighborhood levels of PM2.5
Compared to those living in neighborhoods with the lowest exposure, we found that individuals living in neighborhoods with the highest long-term PM2.5 exposure were:
- At 20% higher risk of SARS-CoV-2 infections.
- At 51% higher risk of COVID-19 mortality.
- More likely to be Hispanic and more socioeconomically vulnerable.
We estimate that 9% of COVID-19 deaths during this time would have been prevented if all of California met the National Ambient Air Quality Standards for PM2.5. The full publication is available here.
