Human hydatidosis (Echinococcosis) is a neglected disease in Iran

Human Echinococcosis is zoonoti parasitic disease caused by small tapeworm. The worm has four species. The adult worms live in the intestine of canidae especially dogs. This animal plays as a main host. The human and slaughtered animals are intermediate host as sheep, goat, cow and camel. The size of adult worm (3-7) mm long and has (3-5) segments. The egg in the segment of worm is ingested by suitable intermediate host. The eggs are hatched as a oncosphere that penetrate in intestinal mucosa and inter to blood circulation and logged in liver or others organs. They begin to grow slowly developing as a large cystic hydatid.
Many times the cyst exist in human until death time. The cysts grow slowly in long time although cysts exist in all human’s organs. Surgical removal of cysts until recently was the only form of possible therapy and prevention and control is very difficult.
The health and economic losses caused by disease are significant, thus we must try the prevention and control of this disease in Iran
