AIDSinfo is a U.S. Department of Health and Human Services (DHHS) project providing information on HIV/AIDS clinical trials and treatment. It is the result of merging two previous DHHS projects: The AIDS Clinical Trials Information Service (ACTIS) and the HIV/AIDS Treatment Information Service (ATIS).

AIDSinfo is a central resource for current information on federally and privately funded clinical trials for AIDS patients and others infected with HIV. AIDS clinical trials evaluate experimental drugs and other therapies for adults and children at all stages of HIV infection -- from patients who are HIV positive with no symptoms to those with various symptoms of AIDS.

As the main dissemination point for federally approved HIV treatment and prevention guidelines, AIDSinfo provides information about the current treatment regimens for HIV infection and AIDS-related illnesses, including the prevention of HIV transmission from occupational exposure and mother-to-child transmission during pregnancy.

Mission Statement

To offer the latest federally approved information on HIV/AIDS clinical research, treatment and prevention, and medical practice guidelines for consumers and health care providers.


HIV/AIDS patients, their families and friends, health care providers and researchers.
