Introduction: Intestinal parasitic infections (IPIs) play a major role in global disease burden with significant morbidity. The most vulnerable age group was school going children and is transmitted through soil. About 90% of infected individuals remain asymptomatic. The present study was designed to screen for IPI among school children in Karaikal, to identify the asymptomatic infections and to assess the type and occurrence of IPIs. Methodology: A cross-sectional study was carried out from July to September 2018 among school children in the age group of 6–14 years after getting ethical clearance. A total of 335 single stool samples were collected. The samples were subjected to macroscopic examination, microscopic examination and subjected to concentration techniques such as salt floatation and formal ether sedimentation technique. Two separate fresh stool smears were made on the microscopic slides for trichrome and modified acid-fast staining. The results were calculated as percentage, frequency/proportion, and Chi-square test using IBM SPSS software version 19. Results: Only 90 (28%) out of 324 stool samples were positive for the presence of intestinal parasites. The sensitivity of formal ether sedimentation technique (58%) was higher than other techniques. None of the ova of helminths detected. Modified acid-fast staining was negative for coccidian parasites. Conclusions: The low prevalence of protozoan parasites and total absence of helminths in the study revealed the effective role of nationwide deworming program and Swachh Bharat Abhiyan program. However, anthelminthic does not cover the protozoan parasites and it exists among asymptomatic healthy population.
