Tuberculosis (TB) facts
- TB is an infectious disease that's transmitted from person to person.
- There are many different types of TB.
- A bacterium, Mycobacterium tuberculosis, causes the disease.
- There are many risk factors for TB. Clinical symptoms and signs of pulmonary TB include fever, night sweats, cough, hemoptysis (coughing up blood-stained sputum), weight loss, fatigue, and chest pain.
- Physicians definitively diagnose TB by culturing mycobacteria from sputum or biopsy specimens, but health-care professionals presumptively diagnose TB by history, physical exam, skin testing, and chest X-rays.
- Treatment of TB infection is related to the type of TB infection and often requires extended treatments (months) with one or more anti-TB drugs.
- Complications of TB range from none to death and include lung, kidney, and liver problems that can be severe.
- The prognosis for appropriately treated TB infection is good. The prognosis declines in people who develop complications or who have had previous TB treatments.
- Prevention of TB involves both early treatment to reduce transmission and isolation of the infected person until they are no longer contagious. There is a vaccine against TB, but it is not used routinely in the U.S. because of efficacy issues and other problems.
