Background: Intestinal parasitic infections are widespread in tropical and subtropical regions, particularly among children due to poor hygiene and sanitation. In India, soil-transmitted helminths (STH) such as Ascaris lumbricoides, Trichuris trichiura, and hookworms are endemic. Intestinal worm infestations are a major public health concern in developing countries, particularly among children. This study aimed to determine the prevalence and associated risk factors of intestinal worm infestations among school-going children in West Bengal, India. Methods: A cross-sectional study was conducted among 106 school-going children (aged 5–15 years) in West Bengal. A written and informed consent was taken from the parents regarding the study in his/her vernacular language and English Stool samples were examined microscopically for worm infestation, and a structured questionnaire collected demographic and socioeconomic data. Results: The overall prevalence of intestinal worm infestation was 60.83%, with Ascaris lumbricoides being the most common parasite. Factors significantly associated with infestation included poor sanitation, low socioeconomic status, and lack of footwear. Conclusion: High prevalence indicates the need for improved sanitation, health education, and regular deworming programs in schools.
