With 20 years of evidence demonstrating HIV treatment to be highly effective in reducing the transmission of the virus, recent evidence has empirically proven that people living with HIV with an undetectable viral load cannot transmit HIV sexually.

Based on this evidence, the Prevention Access Campaign created and disseminated a new public health campaign in 2016 branded "Undetectable = Untransmittable" (U=U) to spread the information and help decrease HIV stigma. While the U=U message is endorsed by the CDC and the National Institutes of Allergy and Infectious Disease, little is known about its breadth and reach.

For a study published in AIDS and Behavior, a research team led by CUNY SPH doctoral student Pedro B. Carneiro describes the socio-demographic characteristics and sexual behaviors associated with having heard of and trusting in U=U in a national sample of HIV-negative participants.

The researchers derived data from the Together 5,000 , an internet-based national cohort of cis men, trans men and trans women who have sex with men. Approximately six months after enrollment, participants completed an optional survey included in the present cross-sectional analysis.

Among those aware of U=U, 42.3 percent indicated they trusted it, 19.8 percent did not, and 38.0 percent were unsure about it. Latinx, Asian, , and Southern participants were less likely to have heard of U=U. Having had a recent clinical discussion about PrEP or being a former-PrEP user were associated with trust in U=U. Willingness to engage in condomless anal sex was positively associated with trust in U=U, and varied based on the partner's serostatus, PrEP use and viral load.

"Although we found high rates of awareness and low levels of distrust, our study indicated that key communities remain unaware and/or skeptical of U=U," says Carneiro. "This underscores the need to continue developing strategies to spread community awareness and build trust around the message of U=U."
