An Outbreak of Acute Schistosoma mansoni Schistosomiasis in a Nonendemic Area of Brazil: A Report on 50 Cases, Including 5 With Severe Clinical Manifestations

Abstract

This report describes the first time that patients from an outbreak of acute schistosomiasis have been compared to controls. Five subjects (10%) had severe manifestations of schistosomiasis. Diagnosis of the disease and its severity was delayed because physicians did not consider that an epidemic of schistosomiasis might emerge in a nonendemic area.
