A18: Tuberculosis of other organs
Tuberculosis (TB) of other organs refers to a group of conditions where the bacteria that typically affects the lungs spreads to other parts of the body, like the bones, urinary tract, or skin. While transmission occurs through airborne droplets from an infected person sneezing or coughing, it only develops into active disease in some individuals and can then spread within the body. Common symptoms depend on the area affected, but may include pain at the site, systemic symptoms like weight loss and fatigue, or specific problems like spinal pain in bone TB. Over time, the disease can cause significant impairments such as renal failure in kidney TB or neurological issues in TB meningitis. TB of other organs is a serious condition that can be life-threatening if not diagnosed and treated promptly.
