Signs and symptoms of TB

The symptoms of tuberculosis disease depend on the area of the body where the TB bacteria are multiplying. In general, tuberculosis bacteria multiply in the lungs (pulmonary tuberculosis). Tuberculosis disease in the lungs can cause symptoms such as the following:

Intense cough that lasts 3 weeks or more.

Chest pain.

Cough with blood or sputum (phlegm that comes from the bottom of the lungs).

Other symptoms of tuberculosis disease are:

Weakness or fatigue

Weight loss

Lack of appetite

Shaking chills

Fever

Night sweats

The symptoms of TB disease in other parts of the body depend on the affected area.

Note:

People who have latent tuberculosis infection do not feel sick, have no symptoms, and cannot spread TB to others.
