摘要
建立了一个具有充分接种和重复感染两种病毒的流行病模型,在合理的假设下,给出模型的两个基本再生数和两个侵入再生数,得到了模型的平衡点及其稳定性.
This paper sets up two-strain superinfection epidemic model with the hypothesis of perfect vaccination . The representative formulas of the two basic reproduction numbers and the two invasion reproductive numbers are obtained. Under some suitable conditions, the model＇ s equilibriums and their stability respectively are given.
