Tuberculosis (TB): Symptoms & Signs

Tuberculosis is a pulmonary (lung) infection by Mycobacterium tuberculosis bacteria. Tuberculosis can be active (when symptoms occur and the organism can be spread to others) or latent, in which the infection is not causing symptoms because the body's immune system is keeping the infection under control. Fever, night sweats, coughing up blood (hemoptysis), shortness of breath, chest pain, and swollen lymph nodes are some of the symptoms and signs associated with active tuberculosis infection. In certain cases, the bacteria can infect the gastrointestinal tract, meninges surrounding the brain and spinal cord, urinary tract, or other sites within the body, causing symptoms that are specific to those areas.
