A potentially serious infectious bacterial disease that mainly affects the lungs.
The bacteria that cause TB are spread when an infected person coughs or sneezes.
Most people infected with the bacteria that cause tuberculosis don’t have symptoms. When symptoms do occur, they usually include a cough (sometimes blood-tinged), weight loss, night sweats and fever.
Treatment isn’t always required for those without symptoms. Patients with active symptoms will require a long course of treatment involving multiple antibiotics.
Tuberculosis (TB) is a potentially serious infectious disease that mainly affects the lungs. The bacteria that cause tuberculosis are spread from person to person through tiny droplets released into the air via coughs and sneezes.
Once rare in developed countries, tuberculosis infections began increasing in 1985, partly because of the emergence of HIV, the virus that causes AIDS. HIV weakens a person’s immune system, so it can’t fight the TB germs. In the United States, because of stronger control programs, tuberculosis began to decrease again in 1993. But it remains a concern.
