We conducted a community cross-sectional survey of soil-transmitted helminthiasis in humans and dogs in four provinces in northern Laos. We collected and tested human and dog fecal samples and analyzed results against sociodemographic data. The prevalence of Ascaris lumbricoides, Trichuris trichiura, hookworm, and Strongyloides stercoralis was 26.1% (95% confidence interval [CI] = 23.7-28.4%), 41.5% (95% CI = 38.8-44.1%), 46.3% (95% CI = 43.3-49.0%), and 8.9% (95% CI = 7.4-10.4%), respectively. We observed strong heterogeneity for helminthiasis by ethnicity, province, and wealth status, which coincided with a risk profile demonstrating that Mon-Khmer persons and the poorest households are highly vulnerable. Necator americanus was the dominant hookworm species infecting humans and Ancylostoma ceylanicum was the only Ancylostoma species detected. Hookworm prevalence in village dogs was 94%, and the dominant species was A. ceylanicum. Necator americanus was also detected in dogs. It appears that dogs have a role in human hookworm transmission and warrant further investigation.
我们在老挝北部的四个省进行了一项针对人类和狗的土壤传播性蠕虫病的社区横断面调查。我们收集并测试了人类和狗的粪便样本，并根据社会人口统计学数据进行了分析。蛔虫、鞭虫、钩虫和粪类圆线虫的流行率分别为 26.1%（95%置信区间[CI] = 23.7-28.4%）、41.5%（95%CI = 38.8-44.1%）、46.3%（95%CI = 43.3-49.0%）和 8.9%（95%CI = 7.4-10.4%）。我们观察到，按种族、省份和财富状况划分，寄生虫病存在强烈的异质性，这与风险概况相吻合，表明孟高棉人和最贫困的家庭极易受到感染。美洲钩口线虫是感染人类的主要钩虫物种，而旋毛线虫是唯一检测到的旋毛形线虫物种。村狗的钩虫流行率为 94%，主要物种是 A. ceylanicum。犬体内也检测到了美洲钩口线虫。看来，狗在人类钩虫传播中起着作用，值得进一步调查。
