摘要
针对一类只在种群的成年阶段中传播的传染病,建立了分阶段结构的传染病模型。通过讨论找到了各类平衡点存在的阈值条件,并研究了各平衡点的全局稳定性。
An epidemic model with stage-structure consisting immature and mature stages is investigated, and the existence conditions and threshold of various equilibriums are obtained. Moreover, the global stability of epidemic equilibrium and disease-free equilibrium are proved.
