摘要
建立了具有两个感染阶段的疾病传播模型,分别讨论了在常数接种策略下,具有免疫接种年龄的传染病模型的无病平衡态和地方病平衡态的动力学特性,得到了决定疾病是否传播的基本再生数.
In this paper, a disease transmission model with two infective stages and constant vaccination is proposed and analyzed. The effects of constant and age-since-structure vaccination on disease transmission and dynamical behavior of equilibrium in system are respectively discussed. The basic reproduction number that de-termines disease transmission is obtained.
