Persistence and Extinction of HIV Infection with Two Types of Viruses?

摘要：

In this paper, we study an HIV model incorporating two types of viruses which are wild and resistant.Between the extinction and uniform persistence of the disease, we get threshold values:Rs and Rr which are the basic reproductive numbers of wild virus and resistant virus respectively.It is shown that the disease-free equilibrium is globally asymptotically stable and the disease eventually disappears if Rr And Rr＜1.Further, if Rs＜1＜Rr,wild virus is extinct and resistant virus is uniformly persistent. Moreover, if Rs＞Rr And Rs＞1,two types of viruses are uniformly persistent.
