HIV “Undetectable equals Untransmittable” (U=U)


People living with HIV on HIV treatment who have had an undetectable viral load for more than six months and continue to have an undetectable viral load, do not sexually transmit HIV, with or without the use of condoms.

The Consensus Statement of the Prevention Access Campaign is designed to promote “Undetectable equals Untransmittable” (U=U) and the campaign can be endorsed by going on the campaign website.



This news is the most significant development in the HIV world since the advent of effective combination therapy 20 years ago.

The revolutionary advances in HIV science now enhance people’s participation in safe, sex-positive relationships.

Two studies, HPTN 052 and the PARTNER study, published their final findings in 2016, reinforcing the effectiveness of a sustained undetectable viral load. The latter study followed 548 heterosexual and 340 gay male serodiscordant couples who had regular unprotected sex while the HIV-positive partner had an undetectable viral load. Despite over 58,000 anal and vaginal sex acts, no HIV transmissions occurred between the partners.

CATIE has endorsed the campaign by signing the Consensus Statement and has published a number of texts about this subject which can be found on their web site:

In 2017, we encourage all to become a U=U Ambassador and create your own version of the U=U video to help champion this message. #UequalsU!
