Opisthorchiasis

Opisthorchiasis is a parasitic disease caused by species in the genus Opisthorchis. Chronic infection may lead to severe liver disease.

Causes

Opisthorchiasis is caused by the trematodes Opisthorchis viverrini and Opisthorchis felineus. Humans contract the disease by eating raw or undercooked fish containing the larvae of the parasite.

Symptoms

The symptoms of opisthorchiasis can range from mild to severe, and may include fever, fatigue, abdominal pain, and jaundice. In severe cases, the disease can lead to cholangitis, cholangiocarcinoma, and liver cirrhosis.

Diagnosis

Diagnosis of opisthorchiasis is typically made by identifying the eggs of the parasite in a stool sample. Other diagnostic methods may include serology and imaging studies.

Treatment

Treatment for opisthorchiasis typically involves the use of the antiparasitic drug praziquantel. In severe cases, surgical intervention may be necessary.

Prevention

Prevention of opisthorchiasis primarily involves avoiding the consumption of raw or undercooked fish in areas where the disease is endemic.
