The bimodal SARS-CoV-2 outbreak in Italy as an effect of environmental and allergic causes

We read with attention the very recent Editorial by Navel et  al1 in the latest issue of the Journal. The topic intrigued us because we are currently investigating how come Italy is cropped into 2 great coronavirus disease 2019 (COVID-19)-infected macro areas, an upstream (Northern) zone and a downstream (Central-Southern) zone, with respect to the river Po. More recent data from the Italian Ministry of Health assessed that the 7 regions in the Northern macro area account for about 79.81% of the whole severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive population.
