Abstract
It is hypothesized that short-term exposure to air pollution may influence the transmission of aerosolized pathogens such as COVID-19. We used data from 23 provinces in Italy to build a generalized additive model to investigate the association between the effective reproductive number of the disease and air quality while controlling for ambient environmental variables and changes in human mobility. The model finds that there is a positive, nonlinear relationship between the density of particulate matter in the air and COVID-19 transmission, which is in alignment with similar studies on other respiratory illnesses.
Supplementary material
Supplementary MaterialThe data and R code used to generate these results, as well as figures for individual cities in the validation process, are included in the supplementary files. A README is provided to describe the data available, how to generate each figure presented in the paper, and where important variables should be found in the code.
