What are the barriers that could stop HIV treatment becoming HIV prevention?

One of the key strategies involved in trying to bring an end to the HIV epidemic is to increase the proportion of HIV-positive people on antiretroviral therapy (ART), to the point where suppressing their viral load starts to reduce onward infection.

What is usually called ‘treatment as prevention’ lies behind the ambitious new target announced by UNAIDS earlier this year to diagnose 90% of people with HIV worldwide, treat 90% of them, and supress HIV below detectability in 90% of those – in other words to have 72.9% of all the HIV-positive people in the world virally undetectable by 2020.

A symposium session at the recent HIV Research for Prevention conference explored whether this was feasible and how its success could be measured – and heard about the barriers that could impede progress towards the UNAIDS goal.
