Access to antiretrovirals unlikely to reduce HIV infection rates

weaker but before they develop the symptoms of AIDS, the outcome on HIV prevalence depends critically on the behavior of these individuals.

These results suggest that provision of ART to symptomatic AIDS patients and/or those at the earlier stages of the disease is not likely to prevent many new infections. It could even increase transmission of the virus as patients live longer and are healthier. Counseling patients and the rest of society to promote safe sex practices must therefore be an essential part of any strategy if it is to contain and reverse the AIDS epidemic. The model presented here can support health policy makers in resource-poor settings in their difficult task of allocating limited amounts of antiretroviral drugs for the best outcome for their populations.
