ABSTRACT This study evaluated the Prevalence of intestinal parasitic infections among school children and feacal contamination of school premises in urban and rural areas of Imo State, Nigeria. A cross-sectional survey was conducted from February to November 2024, in selected primary schools across Owerri and Orlu zones of Imo State. A total of 2,304 stool samples from children aged 5–13 years were collected and examined using Direct wet-mount technique, Kato Katz technique and formalin ethyl acetate concentration technique. Soil samples were also collected at strategic spots in the school premises to assess environmental contamination, and were examined using formalin ethyl acetate concentration techniques. Structured questionnaires were administered to assess the demographic information of the children. Statistical analysis was performed using R programmer version 4.4.2. The overall prevalence of Intestinal Parasitic Infections was 53.04%, with significantly higher rates in rural (56.06%) than urban areas (49.96%) of Imo state. Ascaris lumbricoides (28.73%) was the most prevalent parasite, followed by Hookworm (16.88%), Strongyloides stercoralis (14.50%), Entamoeba histolytica (12.11%), Schistosoma mansoni (10.29%), Trichuris trichiura (9.98%), Taenia species (7.34%), and Giardia lamblia (7.34%). Rural children showed significantly higher infection rates than their urban counterparts (p = 0.002). Out of a total of 2,304 children examined across urban and rural areas of Imo State, 777 (33.72%) had co-infections. Demographic analysis revealed that younger children and those in lower primary classes were more susceptible. The study revealed widespread soil contamination with intestinal parasites across all sampled locations in Imo State, with higher prevalence in rural areas. Of the 240 soil samples analyzed, 67.10% tested positive for at least one parasite, with Ascaris lumbricoides being the most common, followed by Hookworm and Trichuris trichiura. Orlu zone Rural showed the highest contamination rate, while Owerri zone urban had the lowest. Parasite ova were detected in all sampled sites, with toilet areas exhibiting the highest concentration, followed by classrooms and playgrounds. To effectively reduce the burden of intestinal parasitic infections among children, the study recommends improving sanitation and access to safe water, enhancing health education and public awareness, reinforcing school-based deworming programs, strengthening rural healthcare services, implementing environmental control policies, and ensuring continuous monitoring through epidemiological studies. This study contributes to knowledge by providing updated data on intestinal parasitic infections among school children in Imo State, Nigeria, while also identifying toilet areas as key transmission hotspots, thereby informing targeted, integrated control and sanitation interventions.
