The stochastic process is defined by local rules and involves the following cyclic process: S$\\to$I$\\to$R$\\to$S (SIRS). The open process S$\\to$I$\\to$R (SIR) is studied as a particular case of the SIRS process. The epidemic process is analyzed at different levels of description: by a stochastic lattice gas model and by a birth and death process.
