Signs and Symptoms of Pulmonary Tuberculosis
Pulmonary tuberculosis (TB) is a contagious bacterial infection that primarily affects the lungs. It is caused by the bacterium Mycobacterium tuberculosis. The bacteria are spread through the air when an infected person coughs, sneezes, speaks, or sings.
