Named after Dr. Gerhard Armauer Hansen, who discovered the bacterium in 1873, this chronic infectious disease continues to affect approximately\u00a0200,000 people globally each year, with the majority of new cases reported in India, Brazil, and Indonesia.<\/p>\n\n\n\n<p>Despite its fearsome reputation, leprosy is\u00a0<strong>completely curable<\/strong>\u00a0with modern medicine. Around 95% of the human population has natural immunity to the bacteria that cause leprosy, and with early diagnosis and proper treatment, it need not cause disability or disfigurement. This comprehensive guide will walk you through everything you need to know about leprosy symptoms, diagnosis, and treatment options.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Causes Leprosy?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">The Bacteria Behind the Disease<\/h3>\n\n\n\n<p>Leprosy is caused by two types of bacteria:\u00a0<strong>Mycobacterium leprae<\/strong>\u00a0and the more recently identified\u00a0<strong>Mycobacterium lepromatosis<\/strong>.
