Creutzfeldt-Jakob Disease Incidence, South Korea, 2001–2019

Abstract

We found increasing trends of Creutzfeldt-Jakob disease (CJD) cases and annual incidence in South Korea during 2001–2019. We noted relatively low (5.7%) distribution of familial CJD. An unusually high percentage (≈1%) of patients were in the 30–39 age group, which should prompt a preemptive CJD control system.
