At a glance
In 2023, 78% of gay and bisexual men indicated they were tested for HIV within 12 months of being interviewed, the first step toward engaging in HIV prevention or treatment services. Although awareness of PrEP is widespread among gay and bisexual men (93%) and 45% reported using PrEP, racial and ethnic disparities persist in PrEP use. Understanding and addressing barriers to PrEP use among Black and Hispanic/Latino gay and bisexual men are needed. Among gay and bisexual men with HIV, the majority (96%) are currently taking HIV medicine.

About the data
These descriptive, unweighted data can be used to describe HIV infection among gay and bisexual men and other men who have sex with men and the percentages reporting specific behavioral risk factors, HIV testing, and participation in prevention programs. Monitoring these outcomes is useful for assessing behavioral risk factors and the use of prevention efforts over time and for identifying new HIV prevention opportunities for this population.
