We conducted cross-sectional surveys for taeniasis and cysticercosis in humans, pigs, and dogs in four northern provinces of Laos. Human cysticercosis and taeniasis prevalence was 2.2% (95% confidence interval [CI] = 1.4–3.0%) and 8.4% (95% CI = 6.9–9.9%), respectively. Eating uncooked beef, being male, province of residence, age, and ethnicity were significant risk factors for taeniasis and only province of residence was a significant risk factor for cystiercosis. Thirty-five human tapeworms were recovered during the survey and 33 (94.3%) and 2 (5.7%) were identified as and , respectively. Maximum-likelihood adjusted prevalence of and in pigs was 4.2% (95% CI = 0.5–7.9%) and 55.9% (95% CI = 47.5–64.3%), respectively, and taeniasis in dogs was 4.8% (95% CI = 0.0–11.3%). and were the most prevalent taeniids in the respective pig and human populations and together may suppress transmission.
