What is Tuberculosis?
Tuberculosis is an infectious disease caused by a type of bacteria called Mycobacterium tuberculosis. The germ enters the lung, and grows slowly. It may not become active for many years. TB most commonly stays in the lung, but may also be carried through the blood to other areas such as the kidneys, bones or the brain. TB is easily treated with antibiotics if identified early. Individuals who have been infected with the TB germ, but who have not yet developed active TB, can also be prescribed medication to prevent them from becoming sick in the future.
