In many real phenomena the behaviour of a certain variable, subject to different regimes, depends on the state of other variables or the same variable observed in other subjects, so the knowledge of the state of the latter could be important to forecast the state of the former.

We make a numerical simulation that shows tendencies for recurring epidemic outbreaks and for fade-out or extinction of the infection.
