The detection of hydatidosis in a domestic cat from Trelew – something uncommon but very relevant – rekindles a debate: What

It is the most important parasitic zoonosis there, which constitutes a problem not only of public health but also economic and productive. Caused by the parasite Echinococcus granulosus, this disease manifests with the formation of cysts in organs such as the liver and lungs, following the ingestion of eggs of the parasite.

In this cycle, humans can become accidental hosts upon exposure to environmental risk factors. Efforts to control this disease aim to break the transmission cycle, through the deworming of dogs, the handling of slaughter to avoid the consumption of parasitized viscera, and health education, both for the community and for the specialists themselves.
