Clustering of Necropsy-Confirmed Porcine Cysticercosis Surrounding Tapeworm Carriers in Peru.

The pork tapeworm, , is among the leading causes of preventable epilepsy in the world and is common in rural areas of developing countries where sanitation is limited and pigs have access to human feces. Prior studies in rural villages of Peru have observed clusters of cysticercosis among pigs that live near human tapeworm carriers. Such spatial analyses, however, have been limited by incomplete participation and substandard diagnostic tests.
