Echinococcosis, also known as encapsulated disease, is caused by infection with the tapeworm Echinococcus. Parasites are a large classification of organisms, and encapsulosis is a disease, so they cannot be distinguished from each other. Parasites are lower eukaryotic organisms that have pathogenic properties and can act as pathogens or vectors of disease transmission. Parasites will parasitize a host or attach themselves to the outside of the body to obtain the nutrients needed to sustain them or to develop and reproduce. Borreliosis is caused by infection with Echinococcus granulosus. Healthy people can be infected by accidentally eating food or water contaminated with eggs of Echinococcus granulosus, which can hatch into larvae in the duodenum and parasitize the liver, lungs, brain, bones and other organs, thus causing lesions. People who usually like to eat raw meat, such as sashimi, should have regular checkups, be dewormed, and try to choose cooked food.
