HIV, AIDS, and Mycobacterium Avium Complex

  Mycobacterium avium complex (MAC) is a group of bacteria that are related to tuberculosis. These germs are very common in food, water, and soil. Almost everyone has them in their bodies. If you have a strong immune system, they don't cause problems. But they can cause serious illness in people with HIV (human immunodeficiency virus). With the right combination of medications, however, you can prevent or treat MAC. In some cases, you may need lifelong therapy.

HIV is spread when blood, semen, or vaginal fluids from an infected person enter another person's body, usually through sexual contact, from sharing needles when injecting drugs, or from mother to baby during birth.
