What is HIV?
HIV stands for Human Immunodeficiency Virus.
Human Immunodeficiency Virus, or HIV, is a disease that weakens your immune system and makes it harder for your body to fight infections. If your immune system becomes too weak, infections and cancers that your body could normally fight off can easily take over. This is the last stage of an HIV infection, and at this point, the individual has Acquired Immunodeficiency Syndrome, or AIDS.
