Background: The problem of intestinal parasitic infections (IPIs) in children is one of the most worrisome problems worldwide. The latest estimates indicate that more than 880 million children are in the need of treatment for these parasites. Objective: The aim of this study was to measure the prevalence of IPIs in school-going children in East Sikkim, India, and to assess the efficacy of single-dose albendazole (ALB) in children infected with soil-transmitted helminths (STHs). Subjects and Methods: A total of 300 stool samples were collected from the schoolchildren of government schools of East Sikkim. Samples were processed for the identification of IPIs by direct microscopy and formalin-ether concentration method. Fecal egg counting was carried out for STH by Stoll's egg counting technique, pre- and posttreatment with single-dose ALB. The second stool samples were collected 10–14 days posttreatment of ALB. Cure rate (CR) and the fecal egg reduction rate (ERR), the two most widely used indicators for assessing the efficacy of an anthelmintic, were used in this study. The data were analyzed and the results were interpreted statistically. Results: The overall prevalence of the IPIs was 33.9%. Helminthic infection was 4.6% and protozoan infection was 29.3%. Among helminthes Ascaris lumbricoides and among protozoans Entamoeba spp. were the dominant intestinal parasites. For drug efficacy, A. lumbricoides had CR 55.5% and ERR 81.4%. Moreover, for Trichuris trichiura, CR and ERR was 100%. The study has shown less efficacy against A. lumbricoides infections compared to T. trichiura. Conclusion: The study provides useful insight into the current prevalence of IPIs in school-going children in government schools in East Sikkim region. Keeping in view of less efficacy of ALB, it is necessary to keep the monitoring of development of drug resistance simultaneously.
