ABSTRACT

Background: The WHO targeted to eliminate leprosy from the world as a public health problem by reducing the prevalence to less than 1 case per 10000 population based on the use of multi-drug therapy (MDT). Despite the success of MDT; endemic pools still exist in some countries that have attained the national elimination threshold. Objective: Assess the burden of childhood leprosy and control efforts in Essimbiland of Cameroon. Methods: The records of children patients were reviewed in two main primary health care institutions and 4 primary schools in Essimbiland having 459 pupils were surveyed for leprosy. A purposive sampling of all available registers and pupils was used. Results: A total of 1129 case files were reviewed covering the periods before MDT (1961-1967) implementation in 1982 and post MDT (1982-1999); no records were available from 1968-1991.From chart review; 42 (23.3) new leprosy cases from 1961-1967 and 35 (12.2) from 1982-1998 were from the Mbingo leprosarium. 31(39.7) of 78 childhood leprosy cases from chart review [1961-1967 and 1982-1999] were from Essimbiland. Of the 35 incident childhood leprosy cases from 1982-1998; 24(68.6) were from Essimbiland compared to other divisions. Poor record - keeping on leprosy was common in the study area. Among 459 pupils surveyed in 4 primary schools; 6(1.3) new leprosy cases were identified giving a prevalence of 131 per 10;000 pupils.
