Leprosy (Hansen's Disease), is a chronic infectious disease that primarily affects the peripheral nerves, skin, upper respiratory tract, eyes, and nasal mucosa. The disease is caused by a bacillus (rod-shaped) bacterium known as Mycobacterium leprae (M. leprae).
NIAID's Research on Leprosy
Researchers are exploring more avenues than ever before in the search for solutions to leprosy, now that the genome of M. leprae has been sequenced. NIAID's goals are to discover reservoirs of infection, routes of transmission, and incubation periods so the disease can be stopped before patients even have symptoms. New tests for early detection of leprosy before nerve damage occurs are now being developed.
