Tuberculosis

Tuberculosis (TB) is a severe infectious disease caused by various strains of mycobacteria, most commonly Mycobacterium tuberculosis. TB affects the lungs (pulmonary tuberculosis), but can also manifest outside the lungs (extrapulmonary tuberculosis). People are infected with TB by inhaling airborne droplets produced by infectious TB carriers - for example when coughing or sneezing. Latent tuberculosis infection (LTBI) carriers are asymptomatic and not infectious. About 10% of those with LTBI develop active TB. Read more facts about tuberculosis
