Leprosy (Hansen's Disease)

General Information

Leprosy is a bacterial disease of the skin and nervous system caused by Mycobacterium leprae. The two main types of leprosy are called lepromatous and tuberculoid. Tuberculoid leprosy is not related to tuberculosis.

It can affect the nerves, skin, eyes, and lining of the nose (nasal mucosa). With early diagnosis and treatment, the disease can be cured. People with Hansen’s disease can continue to work and lead an active life during and after treatment.
