摘要
首先针对具时滞和脉冲接种的SEIR传染病模型,分析了模型无病周期解的全局吸引性.然后,基于2013年宁夏流行性腮腺炎的疫情数据,估计脉冲接种周期,并对系统进行了数值模拟,模拟结果与理论结果一致.
In this paper,we firstly analyze the global attraction of disease-free periodic solution for an SEIR epidemic model with time delay and impulse vaccination.Then,based on the data on mumps epidemic in Ningxia in 2013,the impulse vaccination period is estimated,and numerical simulation of the system is carried out,which is in agreement with the theoretical result.
