Fifty-six (74 percent) of the HIV-positive partners had an undetectable viral load at the beginning of the study, and the remainder had a detectable viral load. Meanwhile, sixty-one (80 percent) of the HIV-negative partners believed their partner had an undetectable viral load, while the remainder believed their partner had a detectable viral load or didn’t know their viral load. This left a difference of five HIV-negative men who were either mistaken or uninformed about their partner’s viral load.
Fifty-five (72 percent) of the HIV-negative partners reported unprotected anal intercourse (UAI) with their partner. Among them, 48 (63 percent of the study group) reported insertive UAI—or being the top—while 32 (45 percent) reported receptive UAI (bottoming) without ejaculation and 19 (25 percent) reported receptive UAI with ejaculation. In other words, the HIV-negative partners were more likely to be the top during condomless anal sex.
Of the 61 HIV-negative men who thought their partner had an undetectable viral load, 49 (80 percent) had UAI in the previous three months. Of the 15 HIV-negative men who thought their partner had a detectable viral load or did not know his viral load, six (40 percent) had UAI in the previous three months.
Believing that a partner had a detectable viral load lowered the likelihood of UAI by 84 percent.
