Clinical definition of the Echinococcus test
Echinococcal disease is a zoonotic disease caused by infection due to a tiny parasitic tapeworm called Echinococcus. Humans become infected when they swallow its eggs in contaminated food. The infection is carried to the liver, where cysts form. Persons exposed to feces of cattle, deer, dogs, wolves or pigs are at a high risk of being infected.

Why is the Echinococcus test done?
It is done to check for antibodies which may develop due to exposure to the worm.

What are the common signs/symptoms when the Echinococcus test is done?
A cyst may be asymptomatic unless it is large enough to be felt by physical examination, 10 - 20 years after infection. Common symptoms include:

  • Bloody sputum
  • Chest pain
  • Cough
  • Fever
  • Pain in the abdomen
  • Severe skin itching

Who should do the Echinococcus test (Target population)?
Persons showing the above signs & symptoms and those at a high risk of contracting the disease due to exposure.
