#HPTN 052

The newly released PARTNER2 study documented 77,000 condomless anal sex acts between mixed-HIV-status men; Opposites Attract had 12,000.

Highlights from the research presented at the 9th International AIDS Society Conference on HIV Science in Paris.

Between this study of mixed-HIV-status gay couples and a similar previous study, partners have engaged in about 35,000 condomless sex acts.

The HPTN 052 trial found no transmissions between mixed-HIV-status heterosexual couples when the HIV-positive partner was undetectable.
