The impact of Undetectable=Untransmittable and viral suppression on condomless sex among mixed HIV-status couples in Canada.

ABSTRACT:

Introduction/objectives

Undetectable = Untransmittable (U = U) means that virally suppressed HIV-positive partners cannot transmit HIV. With advancements in HIV care and the increasing number of mixed HIV-status relationships, we quantified U = U agreement (agreeing/disagreeing that U = U is true) among people in mixed HIV-status relationships, assessed response concordance between partners, quantified the association between dyad-level U = U agreement and condomless sex, and estimated interaction effects of viral suppression.

Methods

A cross-sectional opportunistic and snowball sampled survey explored condom use, U = U agreement, viral suppression, sociodemographic/relationship characteristics, and sexual behavior among 306 participants (153 matched dyads) in mixed HIV-stat
