Nearly 3-million AIDS deaths can be averted and over 2,5-million HIV infections prevented  in the next 13 years  by implementing voluntary counselling and testing, mother to child transmission prevention, improved management of sexually transmitted infections and anti-retroviral therapy.This is one of the key findings in a long-awaited report on the costs and benefits of treating HIV/AIDS, released by the Treatment Action Campaign. TAC commissioned the University of Cape Town's Centre for Actuarial Researche to investigate the various treatment and prevention interventions of the HIV epidemic. TAC took the model a step further and calculated the cost of adult anti-retroviral therapy - the cost gradually increases from R224-million in 2002 to R6,8-billion in 2007 to a peak of R18,1-billion in 2015.
