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.

Creutzfeldt-Jakob 病发病率，韩国，2001-2019

我们发现 2001-2019 年期间韩国克雅氏病 (CJD) 病例和年发病率呈上升趋势。我们注意到家族性 CJD 的分布相对较低（5.7%）。30-39 岁年龄段的患者比例异常高（≈1%），这应该促使 CJD 控制系统先发制人。
