Abstract
Hydatidosis is a zoonotic parasitic disease caused by larval stages (hydatid cysts) of cestodes belonging to the genus Echinococcus and the family Taeniidae. Hydatid cyst, which is the larval stage of Echinococcus, is a bladder-like cyst formed in various organs and tissues following the growth of the oncospheres of an Echninoccus tape worm in that specific organ or tissue. The epidemiology and control of hydatidosis is often considered to be a veterinary matter since the disease can be regulated by controlling parasites in animals. However, collaboration between veterinarians and public health workers is essential for the successful control of hydotidosis. Therefore, the objective of this paper was to review The epidemiology, economic and public health importance of hydatidosis. The developmental stage of Echinococcus is that eggs develop to oncospheres, this oncospheres develop to hydatid cyst in the intermediate host and the hydatid cyst if consumed by final host develops to the adult Echinococcus. Human echinococcosis is a zoonotic infection caused by the tape worm of the genus Echinococcus. Echinococcus granucosus granulosis cause cystic echinococcosis (CE), Echinococcus multilocularis cause alveolar echinoloccosis (AE), and Echinococcus vogeli and Echinococcus oligarthus cause polycystic echinococcosis (PE). From these Echinococcus mulitilocularis is rare but is the most virulent, Echinococcus vegeli and Echinococcus oligarthus are the rarest. Hydatidosis is a zoonotic cosmopolitan parasitic disease found in almost all countries of the world. This disease causes a significant economic loss directly by causing organ or carcass condemnation and indirectly by affecting human and animal health which increase the cost for diagnosis, treatment and control of the disease. Public awareness creation about the transmission and control of the disease and its public health significance and collaboration between veterinarians and public health workers in the prevention and control of the disease is mandatory.
