Partners of people on HIV treatment

A new study is looking at the impact HIV treatment has on reducing the risk of HIV transmission. While everyone wants to know these risks, there are hardly any accurate studies, especially in men who have sex with men.

The PARTNER study is looking for couples where one partner is HIV-negative and the other is HIV-positive and on treatment. The study will also look at the different patterns of condom use.

All information from the study will be anonymised and will be in confidence.

Condoms are the safest way to stop HIV transmission. But using them 100% of the time does not always happen, and sometimes condoms break or slip off.

Are you HIV negative with a positive partner? Or HIV positive with a negative partner?

Janey says, "It is really exciting to be a part of a unique study that can answer such an important question on transmission risk and one that will have a big impact on treatment strategies and policies in the future. We are really trying to engage as many couples as possible to enter this important study."
