Leprosy

Chronic disease caused by bacterial infection

Leprosy

Leprosy, also known as Hansen's disease (HD), is a long-term infection by the bacterium Mycobacterium leprae or Mycobacterium lepromatosis. Infection can lead to damage of the nerves, respiratory tract, skin, and eyes. This nerve damage may result in the loss of nociception, which can lead to the loss of parts of a person's extremities from repeated injuries or infection through unnoticed wounds.
