Leprosy, also known as Hansen's disease, is a curable infectious disease that remains endemic in >140 countries around the world. Despite being declared “eliminated” as a global public health problem by the World Health Organization in the year 2000, approximately 200,000 new cases were reported worldwide in 2017. Widespread migration may bring leprosy to nonendemic areas, such as North America. In addition, there are areas in the United States where autochthonous (person-to-person) transmission of leprosy is being reported among Americans without a history of foreign exposure.
