Long-term exposure to air pollution and COVID-19 incidence: A multi-country study.

ABSTRACT: The study of the impacts of air pollution on COVID-19 has gained increasing attention. However, most of the existing studies are based on a single country, with a high degree of variation in the results reported in different papers. We attempt to inform the debate about the long-term effects of air pollution on COVID-19 by conducting a multi-country analysis using a spatial ecological design, including Canada, Italy, England and the United States. The model allows the residual spatial autocorrelation after accounting for covariates. It is concluded that the effects of PM_2.5 and NO₂ are inconsistent across countries. Specifically, NO₂ was not found to be an important factor affecting COVID-19 infection, while a large effect for PM_2.5 in the US is
