Leprosy is a disease caused by bacteria called Mycobacterium Leprae which mainly affects the skin and the nerves. Few signs of leprosy are usually the appearance of white patches on the skin, accompanied by a loss of sensation in the affected areas. The diagnosis and treatment of leprosy is easy and most endemic countries are striving to fully integrate leprosy services into existing general health services. Most countries that were previously highly endemic for leprosy have achieved elimination at the national level and are intensifying their efforts at regional and district levels. This is especially important for those under-served and marginalised communities most at risk from leprosy, often the poor.
