AIDS stands for “Acquired Immune Deficiency Syndrome”. It is caused by a virus called “Human Immunodeficiency Virus”, or HIV.

HIV is incapable of causing direct symptoms, but once the virus enters the body through blood vessels, they will begin to attack the “T4 Lymphocytes” (white blood cells and macrophages) reside within the immune system, weakening the immune system’s ability to self-repair. Meanwhile, some harmless disease such as pneumocystis carinii pneumonia (PCP), which normally do not affect healthy person, begins their infection and thus turning HIV carrier into AIDS patient.
