Under what circumstances is echinococcosis infected? How can I prevent it?

Generally, it is caused by human contact with some animals and accidentally eating insect eggs, which hatch in the human stomach and duodenum, and the larvae follow the portal vein to the liver, causing hydatid disease. Pay attention to personal hygiene and protection, develop a good habit of washing hands before meals, wash fruits and vegetables, and avoid close contact with dogs in endemic areas.

It is forbidden to feed dogs with liver, lungs and other tissues and organs infected with echinococcus, at least after cooking; exterminate wild dogs, wolves, and foxes on the pastures; Dogs are regularly dewormed to eliminate pathogens; Maintain the hygiene of the barn, forage and drinking water to prevent dog fecal pollution; When humans come into contact with dogs and other animals or process fur such as wolves and foxes, they should pay attention to personal hygiene and strictly prevent infection.

Prothiamisole or praziquantel are effective in sheep echinococcosis. Human echinococcosis can be surgically removed, or propimidazole or praziquantel can be used, and the specific method should be consulted by the doctor.

Hydatidosis, also known as echinococcosis, is a disease caused by the larvae of the Echinococcus granulosus infecting humans. The disease is zoonotic. Dogs are the ultimate hosts, and sheep and cattle are intermediate hosts. Humans develop echinococcosis by accidentally eating eggs as an intermediate host.

Echinococcoccosis, also known as echinococcosis, is a chronic parasitic disease caused by human infection with larvae (echinococcus) of the Echinococcus granulosus granulosus (Canis tapeworm).

Echinococosis is a disease caused by the larvae of the genus Echinococcus, such as Echinococcus granulosus and E. multilocularmultilocularis), E. vortonii (Evogeli rausch) and Echinococcus oligoarthris (E. vulgaris).

oligarthrus）。Its morphology, host, and distribution area vary slightly, with Echinococcus granulosus being the most common.

Echinococcus granulosus length consists of only one scolice and 3 individual segments. Adult worms live in the small intestine of dogs, but wild animals such as wolves, foxes, and jackals can also be their definitive hosts. The eggs are round and have a double embryonic membrane, and their morphology is similar to that of tapeworm eggs, and they have strong resistance to the outside world, when the eggs are excreted with dog feces, they contaminate pastures, livestock houses, vegetables, soil and drinking water, and enter the duodenum through the stomach after being swallowed by other intermediate hosts such as humans or sheep.

Through the action of digestive juices, the hexagocyte emerges from the shell and burrows into the intestinal wall, enters the portal venous system with blood circulation, and most of the larvae are blocked in the liver to develop into hydatid cysts (echinococcus); Some of them can escape to the lungs or spread through the lungs to various organs throughout the body to develop hydatid cysts. After the dog ingests the internal organs of sheep or other intermediate hosts containing hydatid cysts, the protocephalic larvae enter the intestinal wall crypts of the small intestine and develop into adult worms (about 7 to 8 weeks) and complete their life historyThe terminal hosts of Echinococcus multilocularis are mainly foxes and dogs, and the larvae (cystocciae) are mainly parasitic in the livers of rodents or humans in intermediate hosts. See.

Hello, the main reason for the general human infection with echinococcosis is contact with dogs, or handling dogs, wolves, fox skins and accidentally eating insect eggs, the eggs hatch in the human stomach, duodenum, release hexagocyte larvae, the larvae follow the portal vein to the liver, hydatid disease occurs.
