Background Human schistosomiasis is one of the most important neglected tropical diseases. Ongoing control measures have markedly decreased the incidence of the disease. There are currently no data on newly acquired infections. Aim The aim of the study was to determine the prevalence of Schistosoma mansoni infection among school children in Gharbia governorate and carry out a malacological survey on common snail hosts. Materials and methods A cross-sectional study was carried out in three rural areas of Gharbia governorate: Tanta, Kafr El-Zayat, and El-Mahala El-Kobra. Parasitological examination of 110 stool samples was performed using direct wet smear, formol–ether concentration technique, and the Kato–Katz method. An immunological test was also performed to detect S. mansoni antigen in urine. Snail vectors were collected from different water streams, identified morphologically, and examined for infection using shedding and crushing methods. Statistical analysis was conducted using SPSS, version 16. Results The prevalence of S. mansoni infection was found to be 1.8% among school children of the studied areas. Risk factors were age and previous exposure to canal water. In the malacological survey, six species of freshwater snails were found and morphologically identified. Biomphalaria alexandrina was widely distributed but did not show any cercarial shedding. Conclusion Although the rate of S. mansoni infection among school children is low, they can be a potential infective pool for the rest of the community.
