Added: 2026-05-16

Tuberculosis (TB) is a bacterial infection that primarily affects the lungs, caused by Mycobacterium tuberculosis bacteria. The bacteria spread through the air when an infected person coughs, sneezes, or speaks, allowing the bacteria to enter the respiratory system of others. TB can cause symptoms including persistent cough, chest pain, coughing blood, fatigue, weight loss, and fever. Diagnosis typically involves chest X-rays, sputum tests, and skin or blood tests. Treatment requires a combination of antibiotics taken for several months to prevent drug resistance. Prevention includes vaccination with BCG (in some countries), early detection, and proper treatment of infected individuals.
