Tuberculosis

Tuberculosis -- or TB, as it’s commonly called -- is a contagious infection that usually attacks your lungs. It can spread to other parts of your body, like your brain and spine. A type of bacteria called Mycobacterium tuberculosis causes it. In the early 20th century, TB was a leading cause of death in the United States. Today, most cases are cured with antibiotics. But it takes a long time. You have to take meds for at least 6 to 9 months. In the 20th century, TB was a leading cause of death in the United States. Today, most cases are cured with antibiotics.
