A report on the epidemiology of hemorrhagic fever based on 2070 cases and 122 deaths experienced by United Nations Forces in Korea has been presented. This disease, unknown in Korea prior to 1951, has been found to be clinically and pathologically the same disease as described by the Japanese in Manchuria.

Despite the fact that the agent has not been isolated, nor the vector or reser voir defined, available data strongly suggest that a mite-rodent pair is implicated in the transmission of the disease. The inability of other investigators to isolate the agent and develop immunological or serological procedures has limited in many respects the epidemiological study of this disease.

I wish to express my sincere appreciation to the officers and enlisted men of the Army Medical Service of the Eighth U. S. Army and the Far East Command who assisted in the investigation of cases and the collection and identification of rodents and their ectoparasites.

This report includes data on 89 cases collected by Col. James H. Gordon, M.C., U.S.A., Chief of the Preventive Medicine Division prior to 31 August 1951.
