Tuberculosis

Infectious disease

Tuberculosis ( tew-BUR-kew-LOH-siss, also TEW-bər-; TB), also known colloquially as the "white death", or historically as consumption, is a contagious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. Tuberculosis initially infects the lungs, but it can also spread to other parts of the body. Most infections show no symptoms, in which case tuberculosis is considered to be inactive or latent.
