Fascioliasis
Fascioliasis, a parasitic disease caused by liver flukes, primarily affects the livers of various mammals, including cattle and humans. This disease, often overlooked in many regions, can have significant economic and health impacts, particularly in the agricultural sector.
What is Fascioliasis?
Fascioliasis is a parasitic infection caused by the liver flukes Fasciola hepatica and Fasciola gigantica. These trematodes typically reside in the bile ducts of infected hosts, leading to severe liver damage. While primarily affecting livestock, fascioliasis can also infect humans, posing a zoonotic threat.

Get A Second OpinionCauses of Fascioliasis
The primary cause of fascioliasis is the ingestion of metacercariae, the encysted larval stage of the liver fluke. These larvae can be found on contaminated vegetation, such as watercress and other aquatic plants. Upon ingestion, the larvae migrate through the intestinal wall, peritoneal cavity, and liver tissue, eventually settling in the bile ducts.
Transmission
Fascioliasis transmission occurs through:
- Consumption of Contaminated Vegetation: Livestock and humans ingest metacercariae attached to plants.
- Water Contamination: Drinking contaminated water can also lead to infection.
- Intermediate Hosts: The lifecycle of the liver fluke involves snails as intermediate hosts, which release cercariae into water bodies, continuing the cycle of infection.
Symptoms of Fascioliasis
The clinical manifestations of fascioliasis can vary depending on the stage of infection.
Acute Phase
During the acute phase, symptoms result from the migration of larvae through liver tissue and may include:
- Fever
- Abdominal pain
- Hepatomegaly (enlarged liver)
- Nausea and vomiting
- Eosinophilia (increased eosinophils in blood)
Chronic Phase
In the chronic phase, the flukes reside in the bile ducts, leading to:
- Biliary colic
- Jaundice
- Inflammation of the bile ducts (cholangitis)
- Gallstones
- Liver cirrhosis in severe cases
Diagnosis of Fascioliasis
Accurate diagnosis of fascioliasis involves a combination of clinical, laboratory, and imaging techniques.
Clinical Evaluation
A thorough clinical evaluation, including a detailed history of dietary habits and exposure to potential sources of infection, is crucial.
Laboratory Tests
- Serological Tests: Detection of specific antibodies against Fasciola antigens can confirm infection.
- Stool Examination: Microscopic identification of Fasciola eggs in stool samples is a definitive diagnostic method, though it may not be reliable in the early stages of infection.
- Liver Function Tests: Elevated liver enzymes may indicate liver damage due to fascioliasis.
Imaging Techniques
- Ultrasonography: Can reveal liver lesions and bile duct abnormalities.
- CT and MRI Scans: Provide detailed imaging of the liver and biliary system, helping to identify the presence of flukes and liver damage.
Treatment Options for Fascioliasis
Timely and effective treatment is essential to prevent severe liver damage and complications.
Anthelmintic Therapy
The primary treatment for fascioliasis involves the use of anthelmintic drugs:
- Triclabendazole: The drug of choice, effective against both immature and adult flukes.
- Praziquantel: Less effective against Fasciola but may be used in combination therapy.
Supportive Care
- Pain Management: Analgesics for pain relief.
- Nutritional Support: Ensuring adequate nutrition to support recovery.
- Management of Complications: Treating secondary infections and managing biliary obstructions, if present.

Book an AppointmentPrevention of Fascioliasis
Preventive measures are crucial to control the spread of fascioliasis, particularly in endemic areas.
Control of Intermediate Hosts
- Snail Control: Implementing measures to reduce the population of snail intermediate hosts, such as chemical molluscicides and environmental modifications.
Safe Food and Water Practices
- Vegetable Washing: Thoroughly washing and cooking aquatic plants before consumption.
- Water Safety: Ensuring access to clean and safe drinking water.
Public Health Education
Raising awareness about the risks of fascioliasis and promoting preventive measures through community education programs.
