Tuberculosis
Tuberculosis (TB) is an infectious bacterial disease caused by Mycobacterium tuberculosis. It is spread from person to person through the air by inhaling airborne particles contaminated with the bacteria. The most common symptom is a persistent cough, and if left untreated, TB can be life-threatening. TB is the leading cause of death from a single infectious agent, surpassing HIV/AIDS. In 2018, 10 million people fell ill with TB, and 1.5 million people died from the disease. Treatment is available, and most people with TB can be cured with a lengthy course of antibiotics. Prevention is key, and the goal is to reduce the prevalence of TB through case detection, treatment, and vaccine programs.
