Tuberculosis

As mentioned earlier, people who develop latent infection are asymptomatic. Although you may be exposed to the microbe, Mycobacterium tuberculosis may remain dormant or asleep and do not cause problems. 

When active infection develops, it typically runs a sub-acute to chronic course. You may experience non-specific constitutional symptoms such as fatigue, unexplained weight loss and loss of appetite, night sweats and intermittent fevers. 

More specific symptoms would depend on the site of the actual disease. For example, in tuberculosis infection of the lung, you may experience prolonged cough and sputum production; and in lymph node disease, you may experience swelling of the lymph nodes.
