Background: Intestinal parasitic infections (IPIs) are endemic worldwide and have been the cause of illness and disease worldwide. Objectives: The study is aimed to estimate prevalence, intensity, and factors associated with IPIs among school children aged 6-12 years. Materials and Methods: This cross-sectional survey was carried out from February to July 2010, in the diagnostic laboratory of Microbiology department. The study group was divided into four groups, namely, Group A; Group B; Group C; and Group D. A total of 1769 eligible children were enrolled for sampling from these schools. For each enrolled child in the study, a standard stool ova and parasite test with formol-ether concentration technique was done for the assessment of the outcome. Results: Among 1224 participants, 714 (58.3%) were boys and 508 (41.5%) were girls. The overall prevalence of IPIs was estimated as 51.5%. Group A 84%, Group B 64.7%, Group C 62.4%, and Group D 39.3%. Single IPIs were 65.7%, among which 48% were helminthic and 19.3% were protozoan. Multiple IPIs were 34.2%, among which protozoan along with helminthic were 25.9%, polyhelminthic were 8.5% and polyprotozoan were 4.2%. Among the IPIs detected, overall prevalence of helminth was 75.9%, protozoan was 24.1%. Among the helminthes hookworm was highest (28%). Among the protozoan Entamoeba histolytica/dispar was highest (14.8%). Conclusions: The study confirmed that prevalence of IPIs is high as 51.5%. Overall prevalence shows an endemic situation. Therefore, it is recommended that local health sectors should make provision for regular examination of parasitosis and deworming.
