What is the meaning of AIDS? This page is about the meaning and definition of AIDS.
AIDS stands for Acquired Immunodeficiency Syndrome.
Acquired immunodeficiency syndrome (AIDS) is a chronic, potentially life-threatening condition caused by HIV.
HIV destroys CD4 T cells — white blood cells that play a large role in helping your body fight disease. The fewer CD4 T cells you have, the weaker your immune system becomes.
One can have an HIV infection for years before it turns into AIDS. AIDS is diagnosed when the CD4 T cell count falls below 200 or you have an AIDS-defining complication.
