考虑一类具有一般非线性隔离函数和接触率的染病年龄结构SIRS传染病模型,研究平衡点的存在性及渐近稳定性,得到正平衡点指数渐近稳定的一般性条件.

英文摘要：

An infection-age dependence SIRS epidemic model with general nonlinear contact rate and general screening function is considered.The existence and asymptotical stability of the equilibria are investigated,respectively.A sufficient condition is obtained,and under which the positive equilibrium is exponentially asymptotically stable.
