Doctors and nurses in ward where blood transfusions were not commonly used understood only half of questions regardless of period on working. In this study, necessity of the education for fresh staffs and re-education for senior staffs in transfusion medicine was confirmed strictly. To prevent virus infection, it is important for all medical staffs to wear gloves in direct exposure to blood.
