Human Immunodeficiency Syndrome (HIV) is a virus that causes Acquired Immunodeficiency Syndrome (AIDS). HIV/AIDS reduces the immunity of the body towards infections and exposes the body mainly to opportunistic diseases. As a matter of fact, HIV/AIDS has no cure but antiretroviral (ARV) treatment measures and other prophylactic measures actually lengthen the lifespan of a person infected with the virus. Walker (2003, P. 4) argues that the HIV epidemic is more severe in developing countries especially in the sub-Saharan Africa where they attributed poverty to being the greatest factor. Additionally, due to the high rates of new infections experienced globally, there is a limitation of funds and resources to treat and manage the new infections worldwide. Therefore, there is really need to integrate both HIV treatment and prevention to reduce the cost of treatment. Due to this I really felt the need to research on the essence of integrating both preventive and ARV treatment measures to be able to predict the prevalence and effects of HIV/AIDS especially in sub-Saharan Africa in the year 2020 and also years after (Salomon et al., 2005, P. 50).
