本文构建并讨论了一类病毒感染的群体动力学模型,得到了模型存在轨道稳定周 期解的充分条件,较好地解释了在病毒持续感染者体内观察到的病毒载量波动现象.
In this paper, a group dynamics model of a virus infection is constructed and discussed. The sufficient conditions for the existence of periodic stable periodic solutions of the model are obtained, which can well explain the observed fluctuations of viral load in the persistent virus infected individuals.
