Tuberculosis (TB) is a potentially serious infectious disease that mainly affects your lungs. The bacteria that cause tuberculosis are spread from one person to another 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.
TB is a contagious and often severe airborne disease caused by infection with Mycobacterium tuberculosis (Mtb) bacteria. TB typically affects the lungs, but it also can affect any other organ of the body.ymptoms of active disease include cough, loss of weight and appetite, fever, chills and night sweats as well as symptoms from the specific organ or system that is affected; for example, coughing up blood or sputum in TB of the lungs, or bone pain if the bacteria have invaded the bones.
