Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. It typically attacks the lungs but can also affect other parts of the body. It is spread through the air when people with infection cough, sneeze, or otherwise transmit their saliva through the air. Most infections are asymptomatic and latent, but about one in ten latent infections eventually progresses to active disease. If left untreated, Tuberculosis kills more than 50% of those so infected.
