It mainly affects the lungs but can also damage other body parts such as the brain, bones, and kidneys. TB spreads through tiny droplets released into the air when an infected person coughs, sneezes, or speaks.

Common symptoms include continuous cough for more than two weeks, fever, weight loss, weakness, chest pain, and night sweating. Early diagnosis is important to prevent complications and transmission. Sputum examination and chest X-rays are commonly used for detection. TB is treatable and curable with proper medicines under programs such as DOTS (Directly Observed Treatment Short-course). Completing the full treatment course is necessary because stopping medicines early can lead to drug-resistant TB. Vaccination with BCG at birth provides protection against severe forms of tuberculosis. Public awareness, good nutrition, clean surroundings, and early testing are important for TB control.
