Diseases Discussion - Tuberculosis .
One of the toughest aspects of tuberculosis is that its bacteria can lodge in a person’s lungs and stay “latent” (inactive) for months or years. About one-third of the earth’s population – 2 billion people – carry the TB bacteria in this latent mode, the World Health Organization says. About one in 10 people with latent infection will someday develop active, contagious TB – often when their immune systems are weak. In healthy people, infection with Mycobacterium tuberculosis often causes no symptoms, since the person's immune system acts to “wall off” the bacteria
It is mandatory to get investigated and clinically examined. The symptoms of active TB of the lung are coughing, sometimes with sputum or blood, chest pains, weakness, weight loss, fever and night sweats
The tests for ruling out Active TB are Sputum for Acid Fast Bacilii, Gen Xpert – RT PCR Technique, AFB Culture .
Other tests are all supporting tests and can be done along with it if required . more
