Evaluating Urban Taeniasis As a Threat to Cysticercosis Elimination in Northern Peru.

Reintroduction of Taenia solium into a region in Peru where it had been eliminated prompted evaluation of the possibility of reintroduction from an urban reservoir of taeniasis. In a cross-sectional study of an adjacent urban area, we found low prevalence of taeniasis (4/1,621; 0.25%), suggesting minimal risk of parasite reintroduction into rural areas through this route.
