研究了一类HIV感染的病毒动力学模型,得到了病毒消除与否的阀值——基本再生数R0,证明了病毒消除平衡点和疾病平衡点的存在性及全局渐近稳定性.
A mathematical model of virus infected by HIV of CD4^+ T cells is studied. The threshold-basic reproductive number which determines whether a virus is cleared or not is obtained. The existence and global stabilities of virus-clear equilibrium and chronic-infection equilibrium are proved.
