ACQUIRED IMMUNODEFICIENCY SYNDROME (AIDS)
The most severe manifestation of infection with the Human Immunodeficiency Virus (HIV). The Centers for Disease Control and Prevention (CDC)<!-- (see) --> lists numerous opportunistic infections and neoplasms (cancers) that, in the presence of HIV infection, constitute an AIDS diagnosis. There are also instances of presumptive diagnoses when a person's HIV status is unknown or not sought. This was especially true before 1985 when there was no HIV-antibody test. In 1993, CDC expanded the criteria for an AIDS diagnosis to include CD4+<!-- (see) --> T-cell count at or below 200 cells per microliter in the presence of HIV infection. In persons (age 5 and older) with normally functioning immune systems, CD4+ T-cell counts usually range from 500-1,500 cells per microliter. Persons living with AIDS often have infections of the lungs, brain, eyes, and other organs, and frequently suffer debilitating weight loss, diarrhea<!-- (see) -->, and a type of cancer called Kaposi's Sarcoma<!-- (see) -->. See HIV Disease; Opportunistic Infection; AIDS Wasting Syndrome.

Acquired Immunodeficiency Syndrome (AIDS)
A progressive weakening of the immune system accompanied by one or more indicator diseases (opportunistic infections) -- including Kaposi's sarcoma, invasive cervical cancer, pneumocystis carinii pneumonia, and wasting syndrome. In AIDS, common immune system deterioration is marked by a depletion of T-helper (T 4/CD4) cells, which help stimulate antibody production. AIDS is commonly thought to be caused by a retrovirus, HIV.

Human Immunodeficiency Virus (HIV) / Acquired Immunodeficiency Syndrome (AIDS)
defined: AIDS was first reported in 1981 in the United States and has since become a major epidemic, killing nearly 12 million people and infecting more than 30 million others worldwide. The disease is caused by HIV, a virus that destroys the body's ability to fight infections and certain cancers.
explained: Listen to a detailed explanation.

AIDS
Acquired immune deficiency syndrome or acquired immunodeficiency syndrome (AIDS or Aids) is a collection of symptoms and infections resulting from the specific damage to the immune system caused by the human immunodeficiency virus (HIV) in humans, and similar viruses in other species (SIV, FIV, etc.). The late stage of the condition leaves individuals susceptible to opportunistic infections and tumors. Although treatments for AIDS and HIV exist to decelerate the virus' progression, there is currently no known cure. HIV, et al., are transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk. This transmission can come in the form of anal, vaginal or oral sex, blood transfusion, contaminated hypodermic needles, exchange between mother and baby during pregnancy, childbirth, or breastfeeding, or other exposure to one of the above bodily fluids.
