TB (Tuberculosis) is a disease caused by Mycobacterium tuberculosis bacteria that are spread from person to person through the air. TB usually affects the lungs. It can also affect other parts of the body, such as the bones, lymph nodes, kidneys, the stomach, the spine or the brain. Not everyone infected with TB bacteria becomes sick.

TB is a serious disease that is treatable and curable with 6 months of special TB medication.  Some people who are very ill with TB may need longer treatment.  Most people do not need to be hospitalized for treatment; they can take TB medication in the community.
