摘要: 首先, 建立一类包含无症状感染者传播模式的SEI1I2QR传染病模型; 其次, 通过下一代矩阵方法, 计算该模型的基本再生数, 对模型进行动力学分析, 并给出传染病灭绝和爆发的阈值条件; 最后, 结合病例数据进行数值模拟, 对模型参数进行灵敏度分析.

关键词: 传染病动力学, 数值模拟, 基本再生数, 稳定性

Abstract: Firstly, we established a class of SEI1I2QR infectious disease models that included  transmission mode of asymptomatic infected individuals. Secondly, by using the next generation matrix method, we calculated the basic reproduction number of the model, performed the dynamic analysis of the model, and gave the threshold conditions for the extinction and outbreak of infectious disease. Finally, combined with  epidemic data, the sensitivity of the model parameters were analyzed through numerical simulations.

Key words: dynamics of infectious disease; , numerical simulation, basic reproduction number, stability
