 Due to the fact that a large part of infected people do not show evident symptoms of the disease, we claim that in the regions with a lower epidemic risk, i.e. the central and south part of Italy, the epidemic , although probably already very diffused, should not be as lethal as in the northern part of Italy due to a different a-priori risk exposure .

 Our framework can be extended and tested on other epidemic data, such as those on seasonal flu .
