Leprosy, also known as Hansen's disease, is a long-term infection caused by the bacterium Mycobacterium leprae. Symptoms include granulomas of the nerves, respiratory tract, skin, and eyes. This may result in a lack of ability to feel pain, which can lead to the loss of parts of extremities due to repeated injuries or infection due to unnoticed wounds.
