What is dog tapeworm disease?

According to doctors, dog tapeworm disease is a disease caused by tapeworms of the Echinococcus genus. The genus Echinococcus has about 10 species. The two main species that cause disease in humans are: E. granulosus and E. multilocularis.

E. granulosus species causes cystic echinococcosis. This species’ main hosts are domestic dogs, wild dogs… Intermediate hosts are herbivores, especially sheep.

Disease caused by Echinococcus dog tapeworm larvae has clinical manifestations that depend on the species of dog tapeworm infected. The disease is characterized by slow development, and for a long time there may be absolutely no symptoms.

Cysts are commonly found in the liver, followed by the lungs and other organs such as the kidneys, spleen, heart, nervous system or bones. If not detected promptly, hydatid disease will cause: Frequent fatigue, weight loss, diarrhea, itching around the anus, epilepsy, weakness, and anemia.

“Everyone is capable of being infected with dog tapeworm larvae and can become infected if they eat dog tapeworm eggs. People get sick by swallowing dog tapeworm eggs when eating foods contaminated with tapeworm eggs. dogs or humans after having direct contact with infected dogs, foxes, and ferrets,” emphasized Dr. Nguyen Van Hoang, Department of Thoracic Surgery, Military Hospital 108.

– Cut the transmission route by not feeding dogs uncooked viscera;

– Burn or deeply bury the internal organs of the dead intermediate host;

– Periodically deworm dogs at high risk, reducing the number of individuals in the herd.
