Navigating the Viral Divide: Sexual and Gender Minority Community Perspectives on Treatment as Prevention

Since it was established that HIV-positive individuals who maintain an undetectable viral load are unable to sexually transmit HIV (U=U), treatment as prevention (TasP) has become an important biomedical HIV prevention option. Many have remained optimistic that TasP, combined with pre-exposure prophylaxis (PrEP), will help close the "viral divide" between those living with and without HIV. This qualitative interview study of 62 sexual and gender minority (SGM) individuals of mixed serostatuses explored community perspectives regarding TasP, including the meaning of undetectability and how U=U impacts understandings of serodifference. Five key themes emerged from interviews: (1) undetectable does not equal HIV-negative, (2) PrEP is more promoted than TasP, (3) TasP increases openness to serodifferent sex, (4) rejection of TasP absolutism, and (5) the importance of layering prevention strategies. These findings suggest that while TasP is helping to bridge the viral divide, serostatus distinctions remain prevalent and important to many SGM individuals.
