Abstract

About two billion people in the world’s population are affected by the soil-transmitted helminth infection, with children being the most affected with Soil Transmitted Helminth infection.[1] India alone contributes nearly 25% to the total global cases, with 220.6 million children in need of preventive chemotherapy. [2] In view of the above context, the present study was conducted with the aim and objective of to the prevalence of soil-transmitted helminth (STH) infection and its risk factors. Material and Methods: Study Design: A Cross-sectional Observational Study Study Setting: Department of Microbiology, AIIMS, Raipur, from January 1 to June 30, 2023 (6 months). Sample Size: 384 (n=Z2 1-ά/2 P(1-P)/d2). P=50%, CI=95%, d=5% Absolute Precision. Results: STH prevalence was 13.3%, more in males (68.8%), and significantly high (62.5%). P < 0.05) in school-going children between 6 and 12 years of age. The predominant STH was Ancylostoma duodenale (56.2%); STH infection was much less (12.5%) in those practising handwashing with soap. Fifty percent of children had an STH infection even after receiving deworming within the past six months. More egg counts—216 eggs per gramme of faeces—were found in 29 cases by the KK method. Entamoeba histolytica (56.5%) was predominant among non-STH infections. Conclusion: Contrary to the assumption of 50% prevalence, the actual prevalence was very low, only about 13.3%. School-going children aged 6–12 years were more affected, and handwashing with soap was the key factor in preventing STH infection. The proportion of participants having toilet facilities and using footwear regularly had no role in STH prevention.
