Objective. To evaluate the association between exposure to environmental levels of PM2.5 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 PM2.5 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 PM2.5 (OR 1.27, CI95%: 1.25 to 1.29). When performing the multivariate analysis, an OR of 1.39 (CI95%: 1.36 to 1.43) was observed. Conclusions. Chronic exposure to elevated levels of PM2.5 is associated with increased death risk from COVID-19.
