Hyatid Disease (Enhinococcosis)

Is worldwide, yet rare in humans.

This tapeworm infection is acquired through milk, vegetables or water contaminated with animal faeces or by direct contact with infected animals (dog, fox, sheep, and cattle).
The tapeworm larval then encrypts in the liver, lungs, and other organs.

Years can pass before symptoms develop depending on the size and location of the parasites.
Liver cysts are abdominal discomfort, nausea, and vomiting.

If a cyst ruptures, bleeding can cause sudden death.

Cysts in lungs may cause a cough, shortness of breath, and even pneumonia or lung abscess.
Blood tests may defect tapeworm antibodies and chest x-rays or abdominal ultrasound may visualize the cysts.

Surgical treatment is often necessary but drugs can also regress the cysts.
