Abstract

In this paper we present an epidemic model affecting an age-structured population. Weshow by numerical simulations that this demographic structure can induce persistentoscillations in the epidemic. The model is then extended to encompass a stage-structureddisease within an age-dependent population. In this case as well, persistent oscillationsare observed in the infected as well as in the whole population.
