Prevention of Leprosy

Abstract

Leprosy evolves over a long period and after the time of contact it takes long time before pathological changes become evident. Prevention may be achieved by increasing the level of detection and controlling the risk factors. In this paper, the methods of prevention of leprosy are described. Primary prevention, or prophylaxis is of prime importance and this can be achieved by reducing an individual's susceptibility as well as by reducing his/her exposure to susceptible individuals. The former needs general health promotion, immunoprophylaxis and chemoprophylaxis. The latter is achieved by isolation and early detection of cases. A critical review of merits and demerits of these measures is presented. Secondary prevention is through early detection of cases and their prompt treatment. Tertiary prevention is the prevention of deformities and rehabilitation of those who are already disabled.
