AbstractDespite improvements in environmental sanitation and healthcare, the infection rate of soil-transmitted helminths (STHs) remains high in low socioeconomic regions of developing countries including Vietnam. This study aimed to determine the prevalence and intensity of STH infections among primary school children in Meo Vac, Ha Giang: a poor mountainous province in Vietnam. A descriptive cross-sectional study was conducted from October to November 2023, involving 400 participants. The Kato-Katz method was used to identify and quantify STH infections. Out of the 386 children assessed, 76.1% were infected with at least 1 type of STH. The most common infections were with Trichuris trichiura and Ascaris lumbricoides (47.0%). Mixed infections were identified in 121 children, with 77 cases of co-infection with A lumbricoides and T trichiura, 13 cases of A lumbricoides and hookworms, 8 cases of T trichiura and hookworms, and 23 cases involving all 3 STH types. Most infections were of light intensity, with a few moderate-intensity cases of A lumbricoides. Primary school students in Meo Vac, Ha Giang, Vietnam, continue to experience high infection rates of STHs in 2023. The majority of infections were of light intensity. To address this issue, government efforts should focus on educating the public about STH causes, transmission routes, and negative impacts. Improving personal and environmental hygiene and ensuring access to clean water are essential measures.Copyright © 2025 the Author(s). Published by Wolters Kluwer Health, Inc.
