Objective: To evaluate the association between exposure to environmental levels of PM_2.5 and mortality from SARS-CoV-2 in inhabitants of Mexico City.

Material and Methods: A secondary analysis with the total number of deaths from COVID-19 in residents of Mexico City as well as 25 municipalities in the interior of the Republic was carried out. Environmental levels of PM_2.5 were between 2018 and 2021. Bivariate analysis and multivariate logistic regression were performed.

Results: A total of 1,083,175 cases of COVID-19 were included, with 57,384 deaths (5.3%), of which 30,561 were in residents with exposure to more than 20 μg/m³ of PM_2.5 (OR 1.27, CI 95%: 1.25 to 1.29). When performing the multivariate analysis, an OR of 1.39 (CI 95%:1.36 to 1.43) was observed.
