New CDC Data on HIV in the U.S.

Summary

Today, the Centers for Disease Control and Prevention (CDC) published data from the 2024 cycle (June 2024–May 2025) of the Medical Monitoring Project (MMP). MMP is the only source of locally and nationally representative information on behavioral and clinical factors that affect HIV treatment success and risk of HIV transmission among U.S. adults with HIV. This data release can be used to monitor progress towards national and local HIV prevention and treatment goals and inform planning and resource allocation to improve the health and well-being of people with HIV.

Key findings from the 2024 MMP cycle include:

• Antiretroviral therapy (ART) use is high, but adherence remains a challenge—especially among younger people with HIV. Access and adherence to antiretroviral therapy (ART) are key to HIV treatment success. Although most (80%) were prescribed HIV treatment in the past year, only 63% of people currently on ART reported taking every dose as prescribed in the past month; many reasons for missing ART doses were reported. These data illustrate substantial need for improvement among all age groups, particularly younger people with HIV.
• Structural and other factors continue to negatively impact people with HIV in the United States. Structural challenges that can prevent people with HIV from achieving optimal health include unstable housing or homelessness (20%), hunger or food insecurity (22%), and unemployment (15%). Other factors that negatively affect quality of life for people with HIV include aspects of physical, mental, and emotional health and experiencing HIV stigma.

• Eliminating barriers to accessing and using HIV prevention strategies could reduce HIV transmission risk. Many people with HIV use a variety of strategies to prevent transmission such as having sex while having sustained viral suppression, condom-protected sex, condomless sex with a partner on PrEP, or having sex with a partner with HIV. Among adults with diagnosed HIV, in the previous 12 months, 38% had talked to a health care provider and 18% talked to an outreach worker, counselor, or prevention worker about how to prevent HIV or STIs, and 28% received free condoms.

• Many people with HIV have unmet needs for services that support their health. Access to ancillary services could help people with HIV maintain their well-being, but many have unmet needs for services, including dental care (24%), meal or food services (15%), and shelter or housing services (15%).

These findings illustrate that, despite areas of progress in recent years, more can be done to broaden the reach of HIV prevention programs and services and improve quality of life for people with HIV.
