In a review of 123 cases (including 4 deaths) of tsutsugamushi disease which occurred in Akita and Niigata Prefectures during a period from 1976 to 1980, we found 5 cases (died: 4, recovered: 1) which showed a hemorrhagic tendency in the course of illness. Consequently, it was considered that this symptom might be caused by the disseminated intravascular coagulation (DIC) in reviewing carefully the clinical records of those cases, especially on the subject of coagulation studies.
