Abstract

Abstract.

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 , , hookworm, and 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. was the dominant hookworm species infecting humans and was the only species detected. Hookworm prevalence in village dogs was 94%, and the dominant species was . was also detected in dogs. It appears that dogs have a role in human hookworm transmission and warrant further investigation.
