Answer

Since the discovery of HIV and its link to AIDS, great strides have been made in understanding its biology and in developing effective treatments. The difficulty in dealing with HIV on a global scale is largely due to the fact that HIV infection is far more common in resource-poor countries.

In the developed world, antiretroviral therapy has greatly improved prognosis and increased survival rates. Public education programs have raised awareness such that testing and prevention of infection are more common. Both of these approaches are difficult in countries with undereducated or underfunded populations.

A thorough discussion of the history of AIDS and the biologic link between HIV and AIDS can be found in an article entitled " The relationship between the human immunodeficiency virus and the acquired immunodeficiency syndrome " at the National Institute of Allergy and Infectious Diseases Web site. The document was originally written in September 1995, prior to the advent of highly active antiretroviral therapy (HAART), which has significantly improved AIDS-free survival in persons infected with HIV. This version was updated March 2010.
