Hydatid Disease
Hydatid disease, also known as echinococcosis, is a parasitic disease that affects both humans and animals. It is caused by the ingestion of the eggs of the Echinococcus granulosus. The eggs hatch in the intestines and the larvae migrate to various parts of the body where they form hydatid cysts.
The symptoms of hydatid disease depend on the location and size of the cysts. They can range from no symptoms at all to severe complications such as anaphylactic shock if the cysts rupture.
Treatment for hydatid disease typically involves surgery to remove the cysts, along with medication to kill any remaining larvae.
