Prevalence of Schistosoma mansoni Infection in Four Health Areas of Kisantu Health Zone, Democratic Republic of the Congo.

Abstract

Background. Schistosomiasis is a public health problem in Democratic Republic of the Congo but estimates of its prevalence vary widely. The aim of this study was to determine prevalence of Schistosoma mansoni infection and associated risk factors among children in 4 health areas of Kisantu health zone. Methods. A cross-sectional study was carried out in 4 health areas of Kisantu health zone. 388 children randomly selected were screened for S. mansoni using Kato Katz technique and the sociodemographic data was collected. Data were entered and encoded using software EpiData version 3.1. Analysis was performed using SPSS version 21 software. Results. The prevalence of S. mansoni was 26.5% (103); almost two-thirds (63) (61.2%) had light infection intensity. A significant association was found between S. mansoni infection and age (p = 0.005), educational level (p = 0.001), and practices of swimming/bathing (p < 0.001) and using water from river/lake/stream for domestic use (p < 0.001). Kipasa health area had high prevalence of schistosomiasis (64.6%) (64/99; 95% CI 54.4-74.0) compared to other health areas. Conclusion. Schistosoma mansoni infection still remains a public health problem in these areas. There is a need to promote health education and promote behavioral changes in children towards schistosomiasis.
