Tuberculosis an infectious bacteria disease characterized by the nodules in the tissue, especially the lungs.
Tuberculosis is caused by a type of bacterium called Mycobacterium tuberculosis. It's spread when a person with active TB disease in their lungs coughs or sneezes and someone else inhales the expelled droplets, which contain TB bacteria.
Signs and symptoms:
Most people infected with the bacteria that cause tuberculosis don't have symptoms. When symptoms do occur, they usually include cough, weight loss, night sweats, and fever.
Disease can be treated by taking several drugs for 6 to 9 months.
With proper treatment of TB it can no longer spread, then being subscribed with latent TB will prevent people from catching it.
