Tuberculosis (TB) is an infectious disease that usually infects the lungs, but can attack almost any part of the body. Tuberculosis is spread from person to person through the air. It is not easy to become infected with tuberculosis. Usually a person has to be close to someone with TB disease for a long period of time. TB can be fatal if it's not treated, but taking medicine as directed can almost always cure TB.
