Think that salad is completely safe? A parasitic infection known as fascioliasis, or liver fluke disease, can be contracted from common aquatic plants. Understanding this snail-borne disease is vital for your health, especially if you experience unexplained abdominal pain or fever.

What are the main causes of Fascioliasis?

  • This infection is caused by parasitic flatworms, primarily Fasciola hepatica and Fasciola gigantica, commonly known as liver flukes.
  • The primary transmission of fascioliasis to humans occurs through the ingestion of raw aquatic vegetables, like watercress, contaminated with fluke larvae.
  • The parasite's lifecycle involves freshwater snails, which act as intermediate hosts before the larvae encyst on plants, making it a snail-borne disease.
Recognizing Common Fascioliasis Symptoms

Key symptoms of Fascioliasis to watch for

  • Early symptoms can include fever, abdominal pain, nausea, and a significantly high count of eosinophils (eosinophilia) in the blood.
  • The chronic phase involves adult flukes in the bile ducts, potentially causing intermittent pain, jaundice, and inflammation of the pancreas or gallbladder.
  • Long-term infection can lead to severe complications such as biliary obstruction, liver inflammation, and fibrosis if left untreated by medical professionals.

How can you prevent Fascioliasis effectively?

  • Avoid eating raw or undercooked freshwater plants, especially wild watercress, from areas where the parasite is common, including parts of Vietnam.
  • Refrain from drinking potentially contaminated, untreated water from canals, streams, or ponds in endemic agricultural regions where livestock graze.
  • Public health education about the risks of consuming wild aquatic vegetation is crucial for preventing outbreaks in at-risk communities and traveler groups.
