TB causes far more deaths than any other infectious diseases worldwide. It infects one-third of the world’s population, and kills three million people every year (a quarter of the world’s preventable deaths).
Tuberculosis (T.B.) is an infectious bacterial disease caused by Mycobacterium tuberculosis, which most commonly affects the lungs. It is transmitted from person to person via droplets from the throat and lungs of people with the active respiratory disease.
