It causes disease by infecting CD4+ T cells, a type of leukocyte (white blood cell) that normally coordinates the immune response to infection and cancer. When a person's CD4+ T cell count decreases sufficiently he or she is prone to a range of diseases that a healthy person's body is normally able to fight. These diseases include cancers and opportunistic infections, which are usually the cause of death in persons with AIDS. HIV may also infect brain cells, causing some neurological disorders.‎
