[Epidemiologic study of dracunculosis in the Podokwos of the Mandara mountains (northern Cameroon)].
The purpose of the present work is the study of the epidemiological aspects of dracontiasis in an endemic area in Cameroon. The study was undertaken in the central Podokwo settlement in Mora subdivision. It is a mountainous area with a climate characterized by a long dry season, from October to mid-May, and a short rainy season. Two seasonal, streams run across the settlement. The water supply of the community is ensured throughout the year by two well built wells. During the rainy season, shallow unprotected wells are the water sources of about 80% of the inhabitants. Among the 944 subjects studied in our sample, 251 had the disease, corresponding to a prevalence of 26 6%. There is no significant difference between both sexes in the prevalence of the disease in our study. The age group 13-26 years is most affected. The worm load varies from 1 to 5, averagely 1.5. As to the localization of the worms in the body, in 92.7% of cases the worms is located in the lower limbs, the feet alone representing up to 46.8%. Less common sites of localization are the head, the breast, the external genitalia. The maximum rate of infestation is observed between August and September. Desinfection of wells with chemicals would be recommended during this period of time.
