Contrary to what most people think, tuberculosis is completely curable. A combination of at least two different kinds of medication id usually prescribed, and symptoms are relieved in as little as two weeks.

Signs and symptoms ::
One quirk of TB is that the vast majority of people who become infected do not fall ill immediately. Symptoms to look out for include a persistent cough that may produce sputum that is discoloured or has blood in it. Fever, especially in the evenings. Fatigue. Loss of appetite and weight. Night sweats. Chest pain with breathing or coughing. As well as pain in the spine or joints.

Causes and prevention ::
TB is a chronic bacterial infection that can develop after you inhale droplets sprayed into the air (as from a cough or a sneeze) by somebody who is infected. Good ventilation and sunlight decrease the risk of exposure. Doctors are now beginning to question the effectiveness of the widely administered BCG vaccine.
