Just because a partner has undetectable viral load, it doesn’t rule out the need for PrEP or PEP

HIV incidence among the HIV-negative gay men in the PARTNER 1 and 2 studies, due to sex with partners outside the main relationship, was high, and very high in partners who admitted having condomless anal sex with non-primary partners, the 16th European AIDS Conference (EACS 2017) heard recently.
The conference heard that even now, in the latest data from the PARTNER 2 study, only 5% of HIV-negative participants are taking pre-exposure prophylaxis (PrEP), even though over a third have had condomless anal sex with non-primary partners.
The data were presented by Valentina Cambiano of University College London, who is one of the investigators in the PARTNER studies.
PARTNER is arguably one of the most significant HIV prevention studies ever conducted. It studies couples where one partner has HIV and the other does not and its primary aim is to try to quantify the risk of transmission from a person on HIV treatment who has a fully suppressed viral load. While enrolment of heterosexual couples stopped at the end of PARTNER 1 in 2014, it was decided more data on gay men was needed so PARTNER 2, for gay couples only, is still underway.
