"'Wet' leprosy was becoming rare, even by the mid-sixties."

Wet leprosy is the more severe form of the disease caused by the bacterium Mycobacterium leprae.  It leaves the body covered in sores and ulcers, whereas dry leprosy results in nerve endings dying. 

Cases of leprosy in Zimbabwe have declined significantly from 3,000 in 1983 to 35 in 2004, according to the Health and Child Welfare Minister due to active intervention by the Leprosy Programme.
