Earlier this year, a consensus statement from the Swiss National AIDS Commission (EKAF) created global controversy. The statement said that, as long as someone has had an undetectable viral load (which they defined as less than 40 copies/ml) for at least six months; remains adherent to their antiretroviral therapy (ART); is evaluated regularly by their HIV doctor; and has no other sexually transmitted infections (STIs); then they are “not sexually infectious, i.e. cannot transmit HIV through sexual contact.”

The ability of antiretroviral therapy to reduce sexual infectiousness has not been enough to compensate for increases in risky sex among gay men in the Netherlands, according to a recently published study in the journal AIDS. The investigators, who used mathemetical modelling to explain recent increases in HIV diagnoses, conclude that sexual risk behaviour must be reduced to pre-1996 levels for treatment to have an impact on the Dutch gay HIV epidemic.

Now that a vaccine against HIV is not expected within the next decade, an expanding array of other prevention technologies - which now includes microbicides, male circumcision, cervical barriers, PrEP, and genital herpes suppression - were extensively debated at the Sixteenth International AIDS Conference held in Toronto last week, but there remain an array of practical and ethical challenges to research and implementation, according to the Global HIV Prevention Working Group, co-chaired by Dr Helene Gayle, who also co-chaired the Conference.
