Background reading

When HIV treatment is working well for someone living with HIV, it reduces the level of HIV in their body (viral load) and means their immune system can stay strong or get stronger. For more information, take a look at our information booklets, basics and factsheets in the resources pages of this website.

In recent years, there has been a lot of interest in the effect of HIV treatment taken by a person living with HIV on infectiousness (how likely it is that HIV will be passed on to someone else) and on the effect of HIV treatment taken by a person who does not have HIV (whether treatment can prevent infection).

This meeting will focus on HIV treatment as prevention and pre-exposure prophylaxis. The resources below explain some of the theory and studies in these two areas.

HIV treatment as prevention: key research

Information on key research into HIV treatment as prevention to date, from our online resource Preventing HIV.

HIV treatment as prevention: HPTN 052

At the International AIDS Society conference in 2011, the results of a study (HPTN 052) were presented, showing a 96% reduction in transmission when the HIV-positive partner in a couple started treatment early.

Pre-exposure prophylaxis (PrEP): key research

Information on key research into pre-exposure prophylaxis (PrEP) to date, from our online resource Preventing HIV.

Pre-exposure prophylaxis (PrEP): Adherence

At the Conference on Retroviruses and Opportunistic Infections (CROI) in 2012, details from two PrEP trials showed that adherence was very important to the results.
