Tuberculosis News and Research

RSS

Tuberculosis (TB) is a bacterial infection caused by a germ called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but they can also damage other parts of the body. TB spreads through the air when a person with TB of the lungs or throat coughs, sneezes or talks. If you think you have been exposed, you should go to your doctor for tests as soon as possible. You are more likely to get TB if you have a weak immune system.
