B65.2
Schistosomiasis due to Schistosoma japonicum
Clinical Classification Guidelines
Inclusion Terms
- Asiatic schistosomiasis
Medical Intelligence & Overview
Schistosomiasis caused by Schistosoma japonicum, often called Asiatic schistosomiasis, is a parasitic infection prevalent in parts of Asia. This disease results from contact with contaminated freshwater where the parasite’s larvae, called cercariae, penetrate the skin. Once inside the human body, the parasites develop into adult worms that live in blood vessels, causing a range of health issues. Recognizing the causes, symptoms, and diagnostic methods can help in understanding this complex disease.
Causes & Symptoms
Clinical Causes: Contact with freshwater contaminated with cercariae released by infected freshwater snails Swimming, wading, or bathing in such contaminated waters in endemic regions Ingestion of contaminated food or water (less common as a primary transmission route)
Key Symptoms: Fever, chills, and muscle aches, especially during the initial infection phase Abdominal pain and diarrhea Blood in stool or urine (hematuria), depending on the location of infection Enlarged liver or spleen (hepatosplenomegaly) Anemia resulting from chronic blood loss Difficulty breathing or cough if the infection spreads to lungs
Diagnostic & Treatment
Diagnosis Path: Healthcare providers diagnose schistosomiasis through a combination of methods including stool or urine examinations to identify parasite eggs, blood tests to detect antibodies or antigens, and sometimes imaging studies to assess organ damage. The specific location of the infection influences the diagnostic approach. Early detection is crucial for effective management.
Treatment Protocols: Treatment is primarily based on antiparasitic medications like praziquantel, which effectively kills the adult worms. Addressing symptoms and preventing further exposure are important steps. In chronic cases, additional interventions may be necessary to manage organ damage or complications. Preventive measures include avoiding contaminated waters and controlling snail populations in endemic areas.
