<s>[INST] What is Tuberculosis (TB)? [/INST] Tuberculosis (TB) is a bacterial disease found primarily in the lungs. It is spread from person to person through the air. Persons who have tuberculosis in their lungs cough the bacteria into the air and others become infected by breathing in the bacteria. These persons now have latent TB. Without treatment for latent TB infection, approximately 10 percent of the persons who become infected will develop tuberculosis disease sometime in their lifetime. The remaining 90 percent of the people with latent TB carry the bacteria for a lifetime without developing the disease. Source: SCDHEC.
