HIV
Stands for Human Immunodeficiency Virus, which attacks the body's immune system, specifically the CD4 cells (T cells). Over time, HIV can destroy so many of these cells that the body can't fight off infections and disease.
AIDS
Stands for Acquired Immunodeficiency Syndrome. AIDS is the most severe phase of HIV infection. People with AIDS have such badly damaged immune systems that they get an increasing number of opportunistic infections, cancers and other illnesses.
