Abstract

Background: Nigeria is the global hotspot for schistosomiasisdespite several rounds of school-based preventive chemotherapy because reliable data regarding its geographical distribution are lacking and there is a need to know the current prevalence for the control plans. Objective: This study aimed to determine the current prevalence, intensity, and risk factors for urinary schistosomiasis among vulnerable primary school children in Silame, Sokoto, Nigeria. Methods: A cross-sectional laboratory-based study was carried out in April 2021 on 188 primary school children in Silame, Sokoto State, Nigeria. Urine samples were collected and examined using the sedimentation technique for the presence of Schistosoma haematobium eggs. Hematuria was tested using a urine dipstick. Results: Overall, 40 (21.3%) were positive for urinary schistosomiasis with a mean geometric count of 452 eggs/10 ml of urine. Gender was associated (p < /em>=0.0036) with Schistosoma haematobium infection and males 27 (14.4%) recorded higher prevalence than females 13 (6.9%). Hematuria was significantly associated with Schistosoma haematobium infection (p < /em><0.001) and males (13.8%) recorded higher frequency than females (7.5%). Participants with light intensity of infections 26 (65%) were more than moderate 12 (30%), and heavy infections 2 (5%). Factors significantly associated with Schistosoma haematobium infection are gender (p < /em>=0.0036) and water source (p < /em><0.001). Conclusion: The present study showed that a significant number of primary school children in Silame suffer from urinary schistosomiasis. Males are at higher risk of infections than females. Strengthening schistosomiasis surveillance systems to identify hotspots, sustainable chemotherapeutic intervention, and improving health education reduces schistosomiasis prevalence.
