What is PTB?
Pulmonary
Tuberculosis (PTB) is a contagious disease of the lungs caused by the bacteria Mycobacterium tuberculosis. Although the
bacteria generally affect the lungs, they also affect other areas such as the

is referred to as pulmonary tuberculosis (PTB) and the tuberculosis in other
areas as extrapulmonary tuberculosis (EPTB). PTB is more common.
