TED-Ed: What makes TB the world's most infectious killer? - Melvin Sanicas

Tuberculosis (TB) is a major infectious disease known since ancient times. It primarily affects the lungs but can spread to other organs. Historically called the 'White Plague,' TB was romanticized in the Victorian era. Key advancements in understanding and treating TB include the discovery of its bacterial origins by Robert Koch and the development of the BCG vaccine. Despite these advancements, TB remains prevalent, with many cases being latent and hard to diagnose. Current challenges include long treatment durations and drug resistance. New diagnostic tests and treatments are being developed to combat TB more effectively.
