Before revision:  Moreover, the model suggests that an overwhelming part of the population would be in contact with the virus, most of them with no or very little symptoms. We also consider the situation in which the restrictive measures are taken into account by a "reduction factor", and discuss on the one hand how a prompt isolation of asymptomatic infectives would change the dynamics in this framework, and on the other what the time-scale could be in this context; this both in the "mitigation" scenario, in which the measures taken only reduce the epidemic, and in the "eradication" one, in which the measures raise sufficiently the epidemc threshold, as it appears to have happened in China.
After revision:  Moreover, the model suggests that an overwhelming part of the note, we apply our model to the COVID-19 epidemics in Italy. We obtain a good agreement with epidemiological data; according to the best fit of epidemiological data in terms of this model, only 10
