A16: Respiratory tuberculosis, not confirmed bacteriologically or histologically
Respiratory tuberculosis, not confirmed bacteriologically or histologically, refers to a group of conditions affecting the respiratory system, typically the lungs. These conditions are generally caused by the Mycobacterium tuberculosis bacteria, but lack concrete confirmation through laboratory testing or microscopic examination of tissues. The transmission typically occurs when an infected individual coughs or sneezes, releasing the bacteria into the air to be breathed in by others. Common symptoms include persistent cough, sometimes with blood, fatigue, weight loss, fever, and night sweats. Over time and without treatment, the disease can progress to cause serious damage to the lungs, impairing their function and potentially affecting other organs. While these conditions are generally assumed to be a form of tuberculosis based on symptoms, their exact nature remains unconfirmed due to lack of definitive diagnostic tests.
