This is also known as Respiratory Tuberculosis or Koch’s disease.

Pulmonary tuberculosis (TB) is a contagious bacterial infection that mainly involves the lungs, but may spread to other organs. It has a worldwide prevalence of 1.5 billion people infected with the disease. 10% of these infections are drug resistant and therefore harder to treat.

Pulmonary tuberculosis is caused by bacteria called Mycobacterium tuberculosis (M. tuberculosis). You can get tuberculosis by breathing in air droplets from a cough or sneeze of an infected person.

The initial stage of the infection is usually asymptomatic (without symptoms). Most people will recover from primary TB infection without further evidence of the disease. However, in some cases, the disease may become active within weeks after the primary infection, or it may lie dormant for years and later reappear.
