摘要: Heesterbeek and Metz [J. Math. Biol. 31 (1993) 529] derived an expression for the saturating contact rate of individual contacts in epidemiological model. In this paper, SEIR model with is studied. The basic reproduction number R0 proved to be a sharp threshold which completely determines global dynamics outcome disease. If 1, there exists unique endemic equilibrium globally stable disease persists at state if it initially exists. contribution level also analyzed.
