Human immunodeficiency virus is an incurable disease which attacks and destroys the human immunesystem thereby making the body susceptible to all kinds of illnesses. If left unattended to, it can lead to the damaging ofbody organs such as the brain, kidney and the heart which can result to death. Unfortunately this disease has no knowncure till date but through counseling and administering of antiretroviral drugs, the likelihood of dying from it becomesminimal. This study presents the deterministic HIV transmission model. The model has a unique endemic equilibrium point which is locally asymptotically stable if R0 > 1 , DFE of the model was obtained and is shown to be Localasymptotically stable when the associated basic reproduction number was R > 1. We established the numerical simulation of the model which shows that the effective use of condom, counseling or the use of anti-retrovirus drug can lead to effective reduction on HIV transmission. Finally, we discussed that the ART treatment rate will reduce the basic reproduction number R0 hence, leading to the extinction of HIV/AIDS.
