  This article reports a first update on the assesment of the model previously
presented in arXiv:2003.13890v1. New available data have been used to feed the
model and the comparison with real data still shows good agreement. The main
novelty of the model is that it keeps track of the date of infection of a
single individual and uses stochastic distributions to aggregate individuals
who share the same date of infection. In addition, it uses two types of
infections, mild and serious, with a different recovery time. These features
are implemented in a set of differential equations which determine the number
of Carriers, Infections, Recoveries, Hospitalized and Deaths.
