ISSN 0002-9637.The prevalence and characteristics of human taeniasis/cysticercosis and porcine cysticercosis were assessed in an endemic area of the Peruvian highlands. Individuals from 10 communities had stool examinations (N 2,951) and serologic testing for Taenia solium antibodies (N 2,583). The total porcine population present (N 703) was also examined by serology. Cysticercosis is hyperendemic in this area and is associated with an important number of seizure cases. Human seroprevalence by village ranged from 7.1–26.9% (mean, 13.9%). Seroprevalence was higher hmong individuals with a history of seizures but not in those reporting a history of headache or intestinal taeniasis. Prevalence of taeniasis ranged from 0–6.7% (median, 2.5%). Coproantigen detection found 2.4 times more taeniasis cases than did microscopy (direct and after concentration). Age distribution for taeniasis showed a peak at younger ages than for seroprevalence. Porcine seroprevalence ranged from 42–75%. Random effects logistic regression models for human seropositivity demonstrated both in house clustering of cases and a large increase in risk associated with a tapeworm carrier in the house. Besides confirming the close relationshipbetween taeniasis and cysticercosis cases, this large-scale field study demonstrated early age of tapeworm and cysticercosis infections in humans, and short duration of taeniasis infections
