In developing countries like Nepal, gastrointestinal infections due to various parasites are common causes of morbidity and mortality in children. Present study was carried out from June 2013 to December 2013, among the children (<15 years of age) of Kathmandu Valley. Stool samples were collected from total 600 children (350 from four public schools and slum areas of Kathmandu valley and 250 from pediatric department of Tribhuvan University Teaching Hospital). The main objectives of this study were to investigate the intestinal parasitic infections in children below 15 years of age and their risk factors. However, some bacterial pathogens were also investigated. The overall prevalence of parasitic infections was 29.5 %. The rate of parasitic infections in children from community (39.43 %) was higher than that from hospital (15.6 %; p < 0.05). Giardia lamblia was the most common protozoan found to be causing infections in children and among helminths Ascaris lumbricoides was the most common worm isolated. Higher rates of parasitic infections were found in children of illiterate parents (38.17 %), children using untreated drinking water (49.77 %) and children having habit of consuming raw vegetables (31.50 %; p < 0.05). The present study indicated that the rate of infections due to enteropathogenic parasites was high among children of Nepal.
