Abstract

Coker et al. (2020) highlight a strong relationship between exaggerated mortality and pm 2.5 concentration. The hypothesis is that the Coronavirus may attack in a more aggressive way the weaker population subject to chronic cardio-respiratory diseases due to prolonged exposure to particulate matter or due to old age. However, the situation is more complex since the spread of the virus depends on a series of variables difficult to control such as local policies adopted and their timing, the starting point of Coronavirus’ outbreak as well as strong difficulties in collecting data.
