An SIS epidemic model with maturation delay is analysed. It is shown that the disease dies out when the basic reproduction number R -1, and the disease 0 remains endemic when R ) 1 in the sense of uniform persistence. When the 0 disease induced death rate is sufficiently small, the global attractivi

In this paper we propose a continuous-time Markov chain to describe the spread of an infective and non-mortal disease into a community numerically limited and subjected to an external infection. We make a numerical simulation that shows tendencies for recurring epidemic outbreaks and for fade-out or
