Prevalence of schistosomiasis and other intestinal helminth infection among senior primary school children in Makenene Sub-Division, Cameroon
AbstractA study was carried out in four vifiages of Makenene Sub-Division some 85 km north-west of Yaounde, between November 1993 and March 1994 to assess the prevalence and intensity of schistosomes and other helminth infections among senior primary school pupils aged 9–16. An extensive questionnaire was used to collect sociodemographic information and information on water-related activities.The overall prevalence of S. mansoni infection was 228 (23.6%) while S. haematobium infection was practically non-existent 03 (<1%). Infection rates with intestinal nematodes were very high, up to 98% in some villages. Prevalence rates of schistosomiasis varied significantly (P<0.05) between vifiages with the highest (36.2%) recorded in Makenene. Infections with other parasite species encountered were significantly different (P<0.01) while a marked association was observed between water contact activities and the distribution of S. mansoni infections. However, S. mansoni infection intensities were not significantly different (P>0.05) between those with a history of previous infection and treatment and those without.
