Despite 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.
尽管环境卫生和医疗保健有所改善，但在包括越南在内的发展中国家低社会经济地区，土壤传播蠕虫（STH）的感染率仍然很高。本研究旨在确定越南贫困山区省份河江省梅奥瓦克小学生中STH感染的流行率和感染强度。2023年10月至11月进行了一项描述性横断面研究，涉及400名参与者。采用加藤-卡茨法识别和量化STH感染。在评估的386名儿童中，76.1%至少感染了1种STH。最常见的感染是鞭虫和蛔虫（47.0%）。在121名儿童中发现了混合感染，其中77例为蛔虫和鞭虫合并感染，13例为蛔虫和钩虫合并感染，8例为鞭虫和钩虫合并感染，23例涉及所有3种STH。大多数感染为轻度，少数蛔虫感染为中度。2023年，越南河江省梅奥瓦克的小学生仍然面临着较高的STH感染率。大多数感染为轻度。为解决这一问题，政府应致力于向公众宣传STH的病因、传播途径和负面影响。改善个人和环境卫生并确保获得清洁水是至关重要的措施。
