Tuberculosis (TB): Understanding Prognosis & Treatment

Tuberculosis (TB) is a treatable and preventable infectious disease caused by bacteria. It can be fatal if not treated properly, but it is often curable with medication. The time it takes for TB to kill someone varies depending on the severity of the infection, the person's immune system, and the type of TB bacteria involved.

Some forms of TB, such as miliary TB and tuberculous meningitis, are more aggressive and can cause death in as little as a few weeks or months without treatment. Other forms, such as pulmonary TB, can progress more slowly and cause death over the course of several years.

Early diagnosis and proper treatment are essential for preventing death from TB. If you think you may have TB, it is important to see a healthcare provider right away for testing and treatment.
