Diagnosis
(Review)
Acute Schistosoma. 4 to 8 weeks after wading or swimming presents with fever, headache, myalgias, anorexia, malaise, urticarial rash, fatigue, eosinophilia, and transient pulmonary infiltrates.
Look for parasites in stool or urine.
"Diagnosis is on clinical grounds as there is no definitive serological or immunological test. Conventional antibody titers may take three months or more to become positive (PubMed)."
It can cause neurological, pulmonary or cardiac complications that can be severe or life-threatening.
Epidemiologic Risks
Wading or swimming in freshwater in SE Asia or Africa.
