Tuberculosis TB is a disease that can cause a serious illness and can damage a person's organs. Every year more than 25,000 people in the U.S. are diagnosed with TB disease. That's only a fraction of the amount of people who carry the Mycobacterium tuberculosis. Mycobacterium tuberculosis is a rod-shaped bacterium. TB is spread through the air by carriers of the germ. People who breathe the same air can become infected with the TB germ. People who do work around or with people with the TB disease should take medicine. TB infection means that the person has the TB germs but they are in an inactive state. When TB germs enter the body, the immune system builds a wall around them.

The Tuberculin Mantoux PPD skin test is given by placing a substance called PPD Tuberculin under the top layer of the skin with a very small needle and syringe. The doctor will inject the needle into the skin which will only feel like a slight pen prick. A few days later the skin test reaction will be read by a trained health worker. If the skin around the prick israised and it is bigger or the same size as a pencil eraser then the person is likely to have been infected with TB germs. This does not mean he or she has TB disease. You should always retest yourself even if the first test was negative for a few reasons. If your immune system has been weakened, then your immune system may
