Tuberculosis (TB) is a contagious disease caused by the Mycobacterium tuberculosis bacteria, which primarily affects the lungs but can spread to other parts of the body. It is spread through the air when an infected person coughs, sneezes, or speaks, and people nearby inhale the bacteria. Symptoms include a persistent cough (lasting more than three weeks), fever, night sweats, weight loss, and fatigue. TB is preventable and curable with a long course of antibiotics, but it can be fatal if left untreated.
