The model was adjusted for PM2.5 level, sex ratio (female cases: male cases), age [years], food markets (number of food markets per district and population density at the COVID-19 diagnosis). Data for the PM2.5 level (μg/m3) correspond to the average data per district obtained daily from 2012 to 2016.
