Katayama fever

A manifestation of acute SCHISTOSOMIASIS believed to be an immune complex response to eggs laid by maturing schistosomes. Four to six weeks after a schistosomal infection there is fever, enlarged liver and spleen, an urticarial rash and an asthma-like bronchospasm. The diagnosis is important because lack of treatment may lead to severe and permanent neurological damage.
