What are the symptoms of tuberculosis?

The primary stage of the tuberculosis may be symptom-free, or the individual may experience a flu-like illness. In the

secondary stage, called active disease, there might be a slight fever, night sweats, weight loss, fatigue and various other symptoms, depending on the part of the body affected. Tuberculosis of the lung is usually associated with a dry cough that eventually leads to a productive cough with blood-stained sputum. There might also be chest pain and shortness of breath. This secondary stage, if affecting the lungs, is the contagious stage - when the bacteria can be spread to others. Most people infected with the germ that causes tuberculosis never develop active tuberculosis. If active tuberculosis does develop, it can occur two to three months after infection or years later. The risk of active disease lessens as time passes. Most patients with TB have pulmonary disease; extrapulmonary disease usually is seen in immunocompromised patients. TB in an HIV patient may present atypically. These patients have a higher risk for developing multidrug-resistant TB (MDR-TB) and miliary TB. Usually, a longer course of therapy is needed and, because of interactions with other medications, the regimen may require adjustment.
