Hydatidosis is caused by the cestode Echinococcus. Of the 4 species that produce infections in humans, Echinococcus granulosus and Echinococcus multilocularis are most common, causing cystic echinococcosis and alveolar echinococcosis, respectively.

Definitive hosts include dogs and foxes.
Humans can become infected by accidental ingestion of an egg from the feces of a definitive host.

Echinococcal disease is especially prevalent in Central and South America and Asia
