About the Division of HIV/AIDS Prevention

CDC Division of HIV/AIDS Prevention.  Vision: A future FREE of HIV. Mission: To promote health and quality of life by preventing HIV infection and reducing HIV-related illness and death in the United States


As a part of its overall public health mission, CDC provides leadership in helping control the HIV/AIDS epidemic by working with community, state, national, and international partners in surveillance, research, and prevention and evaluation activities. These activities are critically important because CDC estimates that about 1.1 million Americans are living with HIV, and that about 15% of these persons do not know they are infected.In addition, the number of people living with AIDS is increasing, as effective new drug therapies keep HIV-infected persons healthy longer and dramatically reduce the death rate. CDC’s programs work to improve treatment, care, and support for persons living with HIV/AIDS and to build capacity and infrastructure to address the HIV/AIDS epidemic in the United States and around the world.

The Division of HIV/AIDS Prevention (DHAP)

Most of CDC’s HIV/AIDS prevention efforts are the responsibility of the Office of Infectious Diseases National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP). Within this Center is the Division of HIV/AIDS Prevention (DHAP), charged with the mission of preventing HIV infection and reducing the incidence of HIV-related illness and death.

  • The Division of HIV/AIDS Prevention−Intervention Research and Support (DHAP-IRS) provides national leadership and support for HIV prevention research and the development, implementation, and evaluation of evidence-based HIV prevention programs serving persons affected by, or at risk for, HIV infection. The five branches that make up DHAP-IRS are as follows:
    • The Prevention Program Branch develops, plans, implements, and manages strategies and resources for HIV prevention with state and local public health departments, community-based organizations, and other nongovernmental organizations. Along with these comprehensive public health and private sector partners, the branch implements and monitors programs, policies, and activities in support of efforts to prevent HIV/AIDS.
    • The Capacity Building Branch works with partner organizations to strengthen and sustain the capabilities of the HIV prevention workforce of the United States and its territories. The branch does this by ensuring the availability of science-based and culturally appropriate capacity-building assistance, which includes technical assistance, training, information, and technology transfer.
    • The Program Evaluation Branch evaluates the effectiveness, costs, and impact of HIV prevention interventions, strategies, policies, and programs for improvement and accountability; develops and enhances evaluation methods and systems; and serves as a resource for building evaluation capacity.
    • The Prevention Communication Branch develops, produces, and disseminates scientific, statistical, visual, and technical communications on HIV/AIDS for public and private providers, persons at risk, and the general public. Key projects include publications development, public awareness campaigns, national conferences, Web sites, exhibits, and CDC-INFO, for HIV prevention information.
    • The Prevention Research Branch conducts behavioral and operational research to develop, test, and synthesize sustainable interventions to prevent HIV transmission.
  • The Division of HIV/AIDS Prevention−Surveillance and Epidemiology (DHAP−SE) provides national leadership for HIV prevention research and surveillance and the development and testing of effective biomedical interventions to reduce HIV transmission and HIV disease progression in the United States and internationally. The purpose of these activities is to guide the development, implementation, and evaluation of evidence-based HIV prevention programs serving persons affected by, or at risk for, HIV infection. The five branches that make up DHAP-SE are as follows:
    • The Epidemiology Branch designs and conducts epidemiologic, behavioral, and biomedical intervention studies in the United States and internationally to determine risk factors and modes of transmission of HIV infection and to reduce HIV infection and disease progression.
    • The HIV Incidence and Case Surveillance Branch conducts a national program of surveillance and research to monitor and characterize the HIV/AIDS epidemic, and its determinants and impact, to guide public health action at federal, state, and local levels. This program includes surveillance of HIV infection and AIDS in collaboration with state and local health departments to provide population-based data for research, evaluation, and prevention at the national, state, and local levels.
    • The Behavioral and Clinical Surveillance Branch implements scientifically rigorous HIV research studies and surveillance systems that meet critical local, state, and national HIV prevention needs for characterizing persons who are at risk for HIV infection or who have recently acquired HIV or have HIV-related morbidities. The branch also develops and demonstrates best practices of laboratory and prevention technologies to efficiently move them from development into public health practice.
    • The Laboratory Branch supports DHAP’s goals in HIV prevention as they pertain to clinical studies, viral transmission, diagnosis and incidence and intervention research with microbicides, vaccines, and chemoprophylaxis as well as investigates other human and zoonotic retroviruses. The lab also develops new methodologies for HIV detection, quantification, isolation, evolution, animal modeling, and surveillance, including drug resistance.
    • The Quantitative Sciences and Data Management Branch provides statistical, prevention economics, and informatics support for HIV/AIDS scientific and programmatic activities within the division.
