The HIV/AIDS Treatment Information Service (ATIS) is a coordinated Public Health Service project sponsored by seven Public Health Service agencies: the Centers for Disease Control and Prevention (CDC), Agency for Health Care Policy and Research, Health Resources and Services Administration, Indian Health Service, National Institute of Allergy and Infectious Diseases, National Library of Medicine, and Substance Abuse and Mental Health Services Administration. Human Immunodeficiency Virus (HIV) is the cause of Acquired Immunodeficiency Syndrome (AIDS) and AIDS-related complex. HIV may be transmitted through sexual contact or exposure to contaminated blood or other body fluids. AIDS, an acquired deficiency of cell-mediated immunity, has a prolonged incubation period, followed by a progressive, debilitating course. Initial symptoms may include night sweats, fatigue, periodic fever, chills, lack of appetite, weight loss, diarrhea, and depression. As the disease progresses, affected individuals have an abnormal susceptibility to certain recurring infections and certain forms of cancer. Initiated in 1994, ATIS is a free telephone reference service for affected individuals, family members, friends, and health care professionals that provides information about federally approved treatment guidelines for HIV and AIDS. ATIS is staffed by bilingual (English and Spanish) health information specialists who answer questions on HIV treatment options using HSTAT, the National Library of Medicine database of HIV/AIDS treatment information, as well as other Federal resources. ATIS health information service specialists may also provide copies of federally approved HIV/AIDS treatment guidelines and refer callers to an extensive network of Federal information services and national and community-based organizations for treatment-related information. ATIS also has a web site on the Internet that provides direct access to HSTAT free of charge as well as dynamic linkage to additional sources of information on the web (such as the AIDS Clinical Trials Information Service web site).
