Abstract

Two discrete-time deterministic epidemic models are analysed numerically in order to determine their properties and evolutions. It is found that the epidemic oscillates when a small fraction of individuals became not permanently immunised. Smaller the probability that a recovered becomes susceptible, generally larger the period of the oscillations in the infected population.
