Abstract

OBJECTIVE: To determine the prevalence of schistosomiasis (SCH) and soil-transmitted helminths (STH) in the Democratic Republic of Congo, and to assess the capacity of the local health centers for diagnosis and treatment.

METHODS: Cross-sectional school-based survey in two Health Districts in the province of Kwilu. We collected a stool and a urine sample for parasitological examination. Urine filtration and duplicate Kato-Katz thick smears were used for the diagnosis of SCH. Health centers were evaluated using a structured questionnaire.

RESULTS: In total, 526 children participated in the study and the overall prevalence of S. mansoni infection was 8.9% (95%CI: 3.5-13.2) in both districts. The prevalence was higher in Mosango (11.7%; 95%CI: 8.9-14.8) than Yasa Bonga district (6.2%; 95%CI: 1.1-11.4). Urine filtration showed that S. haematobium infection was not present. The combined STH infection prevalence was 58.1% in both districts; hookworm infection was the most common STH found in 52.9% (95%CI: 29.3-62.4) of subjects, followed by A. lumbricoides 9.3% (95%CI: 5.8-15.5) and T. trichiura 2.1% (95%CI: 0.9-4.9). Mixed STH infections were observed as well as SCH-STH co-infection.

CONCLUSION: Further mapping of both SCH and STH burden is needed, and coverage of preventive chemotherapy in school age children should be increased. This article is protected by copyright. All rights reserved.
