Clustering of three cases of Creutzfeldt-Jakob disease near Fukuoka City, Japan

Abstract

During a 4-month period we encountered three patients with Creutzfeldt-Jakob disease (CJD). All lived in a limited area near Fukuoka City in Japan. Such a significantly close spatial and temporal clustering of cases suggests exposure to a common CJD infectious agent. Except for dental-related treatments, there were no evident causative agents common to these three patients.
