Hydatidosis

Abstract

Hydatidosis or hydatid disease, also known as echinococcosis, is a parasitic zoonosis caused by parasitism of echinococcus larva in humans or animals. The main manifestations include space-occupying lesions and compressive symptoms of the involved organs. In China, two types of hydatidosis occur, cyst echinococcosis (CE) caused by Echinococcus granulosus and alveolar echinococcosis (AE) caused by Echinococcus multilocularis . Hydatidosis is an important parasitic disease threatening health of humans and farm animals in northern and southwestern China, which has been legally listed as one of the class C infectious diseases.
