- Environmental factors such as air pollution may contribute to Covid-19 incidence and death.
- This study investigates whether air pollution relates to Covid-19 incidence and mortality in neighborhoods of Los Angeles.
- Los Angeles is a global epicenter for the pandemic with 1,105,989 cases to date.
- Findings suggest that chronic exposure to nitrogen dioxide exerts large effects on Covid-19 disease incidence and mortality.
- Higher levels of air pollution in neighborhoods with high proportions of Latinx and Black people.
- Higher pollution may explain why these groups suffered disproportionately from the pandemic.
In the U.S., more polluted communities often have lower incomes and higher proportions of Black and Latinx people. In addition, Black and Latinx people have higher rates of pre-existing conditions, potentially further exacerbating the risk of COVID-19 transmission and death (Clark et al., 2014, O’Neill et al., 2003). The elevated risk of case incidence and mortality observed in these populations might result partly from higher exposure to air pollution.
