Prevalence of intestinal parasitic infestation in schoolchildren in the northeastern part of Kathmandu Valley, Nepal.
This paper presents the status of intestinal parasitosis in public schoolchildren (1 to 10 classes) in a rural area of the Kathmandu Valley, Nepal. A total of 533 schoolchildren (269 girls and 264 boys, aged 4 to 19 years) were included in this study. A questionnaire was filled out regarding hygienic and other habits, including factors predisposing to parasitic infections. Fecal samples from the children were examined by formol-ether concentration technique. The overall prevalence of parasitosis was 66.6% (395/533) with no significant difference between boys and girls (p> 0.05). Tibeto-Burman children had a non-significant higher prevalence, compared with Indo-Aryan and Dalit children (p>0.05). Half (53.8%; 191/355) of the children had multiple parasitic infections. Altogether, nine types of parasites were recovered. The recovery rate of helminths was higher (76.9%) than protozoa (23.1%). Trichuris trichiura was the most common helminth detected, followed by hookworm, Ascaris lumbricoides and others. Entamoeba coli was the most common protozoan parasite, followed by E. histolytica, Giardia lamblia and others.
