Salient Features of pulmonary tuberculosis

The salient features tuberculosis include:

Wasting of tissues

Exhaustion

Cough

Expectoration, and

Fever

The acute phase resembles pneumonia with high fever. The chronic phase presents itself with low grade fever, accompanied with exhaustion, cough, expectoration and loss of weight. The progression of the disease may be slow with gradual worsening of the cough.  This can lead to erosion of the blood vessel of lungs. The tubercle bacteria may thus subsequently get access to other body organs, thereby,  establishing numerous secondary  foci of  infection.
