Answer:
HIV stands for Human Immunodeficiency Virus. HIV is the virus that causes AIDS.
Your immune system is your body's defense system. While the immune system can control many viruses, HIV targets and infects the same immune system cells that protect us from germs and illnesses. These cells are a type of white blood cell called CD4 cells (sometimes called T cells).
Without medication to control the virus, HIV usually takes over CD4 cells and turns them into factories that produce millions of copies of the virus. As the virus makes copies, it damages or kills the CD4 cells, weakening the immune system. This is how HIV causes AIDS.
