How is the echinococcosis infection acquired?

Echinococcosis is primarily acquired through the ingestion of eggs that are shed in the feces of infected canids, such as dogs and foxes. These eggs can contaminate food, water, or surfaces, making ingestion the most common route of infection for humans. When a person inadvertently consumes these eggs, they hatch in the intestine and develop into larval forms, which can lead to serious health issues, including cyst formation in various organs.

Infection through inhalation, direct contact with infected animals, or vector transmission is not typical for echinococcosis. While certain parasites can be transmitted through those means, echinococcosis is distinctly linked to the fecal-oral route, demonstrating how vital proper hygiene and food safety practices are in preventing this parasitic infection.
