Before revision:  Since infinite solutions honour the data, we show a set of cases by considering different situations. The first set of parameters yields initially a reproduction ratio R0 = 3.33 decreasing to 0.95 in April 8, after the lockdown, but increasing to 1.55 after April 27, most probably due to an increase of the contagion in highly populated slums.
After revision:  Since infinite solutions honour the data, we show different cases. In all of them the reproduction ratio R_0 decreases after early lockdown, but increasing to 1.55 after April 27, most probably due to an increase of the contagion in highly populated slums.
