Leprosy, also known as Hansen's disease, is a chronic infectious disease caused by Mycobacterium leprae. It mainly affects the skin and nerves. The global registered prevalence of leprosy in 2006 was 219,826 cases, with India reporting 1.34 lakh new cases in 2008-09. Key milestones in India's efforts to eliminate leprosy included establishing the National Leprosy Eradication Program in 1983 and introducing multidrug therapy. The program's objectives are to integrate leprosy services into general healthcare and eliminate leprosy at the national level. It utilizes strategies such as early detection, regular treatment, awareness campaigns, and medical rehabilitation.
