混合接种作用下具有非线性传染力的SISV模型

Nonlinear infection force SISV epidemic model under mixed vaccination

研究了混合接种作用下具有非线性传染力和临时免疫的SISV传染病模型,分析该模型无病周期解的存在性,得出了无病周期解全局稳定性的充分条件。

A SISV epidemic model under mixed vaccination, with temporary immunity and nonlinear infection force is studied. The existence of infection-free periodic solution is proved and accordingly the sufficient conditions for the global stability of an infection-free periodic solution are obtained.
