Tuberculosis (TB)

Tuberculosis (TB) is a disease caused by bacteria called mycobacterium tuberculosis that usually attacks the lungs, but can also damage other parts of the body. Tuberculosis spreads through the air when a person infected with TB of the lungs or throat coughs, sneezes or talks. If you have been exposed, you should go to your doctor to be tested. You are more likely to get Tuberculosis if you have a weak immune system.

Symptoms may include:

  • a cough lasting 3 weeks or more
  • unexplained weight loss or loss of appetite
  • coughing up blood or mucus
  • weakness, fatigue or fever


Skin tests, blood tests, x-rays, and other tests can tell if you have Tuberculosis. Taking several medicines for an extended period of time, however, can cure usually active TB, if left untreated it may be fatal.
