Survey on the prevalence of various intestinal parasitic infestations in different geographic regions is a prerequisite to obtain an accurate understanding of the burden and cause of intestinal parasitic infestations in a particular area. The aim of the present study was to determine the intestinal parasitic infestation among children in a semi-urban area.


A total of 335 stool samples were collected, processed, and microscopically examined for intestinal parasites.


One hundred twenty-eight (38%) stool samples showed presence of ova/cysts. Multiple parasites were seen in 42 (32.8%) samples. Among the protozoans, Entamoeba histolytica (55.3%) was the most common followed by Giardia lamblia (40.4%). Ascaris lumbricoides and Hymenolepis nana (24.2%) were the most common helminths detected.


In most of the cases, intestinal parasitic infestation spreads due to low standards of personal hygiene, poor sanitation, non-usage of toilets and an illiterate population, thus suggesting regular surveys to help in devising optimum methods of control.
