The mortality was 6.67%.At the same time,we had treated 13 cases They were below sixty,and also belonged to acute hydropic hepatitis Seven cases were survived.The prognosis was poor in this age group.HBsAg was detected by R-PHA in four cases Among the forty-five cases only one had a history oftransfusion,so we suppo-sed that the sporadic NANB hepatitis in this age group was an important question.
