Echinococcosis (Hydatid disease))-CDCreport

A space occupying disease, in humans caused by the larval stage of the dog tapeworm, Echinococcus granulosus. The signs, symptoms and extent of disease are determined by the size and location of the unilocular cysts (hydatid cyst) that are characteristic of this disease. Symptoms develop as result of pressure, leakage and rupture of cysts. The most common site for the cysts is the liver; less commonly brain, lungs, kidney and uncommonly the heart, thyroid and bone. Cyst may remain viable or dies and calcifies. They may be detected on routine x-ray.

Case classification
Suspected: clinically suspected case with history of contact to animals or animal viscera Probable: diagnosis by plain x-ray, ultrasound or CT, casoni test
Confirmed: Laboratory (PCR , IFAT , ELISA)
