Tuberculosis is an infectious disease usually caused by the bacteria Mycobacterium tuberculosis that generally affects the lungs. It spreads through the air when infected people cough, spit, speak, or sneeze. While it most commonly involves the lungs, causing symptoms like chest pain and coughing, it can also spread to other parts of the body in 15-20% of cases. Proper ventilation, covering coughs, spending time outdoors, and avoiding crowds can help prevent the spread of the disease.
