When and How Much TasP Is Value for Money?

This is a joint post with Mead Over and Denizhan Duran.

In mid-2011, one of the biggest developments in HIV/AIDS research took place. The HPTN 052 study found that early antiretroviral therapy treatment could reduce HIV transmission by 96% in couples where one partner is HIV positive and the other is HIV negative. The study was heralded as the breakthrough of 2011 by Science, and was hailed as a game changer by many others, including UNAIDS, The Economist and The Lancet. The World Health Organization wrote a comprehensive guideline for TasP, or treatment as prevention, in June 2012, asserting that “TasP needs to be considered as a key element of combination HIV prevention and as a major part of the solution to ending the HIV epidemic.”
