Creutzfeldt-Jakob disease (CJD) is a fatal disease presenting with rapidly progressive dementia, and most patients die within a year of clinical onset. CJD poses a potential risk of iatrogenic transmission, as it can incubate asymptomatically in humans for decades before becoming clinically apparent. In this Review, we sought evidence to understand the current iatrogenic risk of CJD to public health by examining global evidence on all forms of CJD, including clinical incidence and prevalence of subclinical disease. We found that although CJD, particularly iatrogenic CJD, is rare, the incidence of sporadic CJD is increasing. Incubation periods as long as 40 years have been observed, and all genotypes have now been shown to be susceptible to CJD. Clinicians and surveillance programmes should maintain awareness of CJD to mitigate future incidences of its transmission. Awareness is particularly relevant for sporadic CJD, which occurs in older people in whom clinical presentation could resemble rapidly developing dementia.

Creutzfeldt-Jakob疾病:对全球发病率,患病率,传染性和孵化的系统评价。

克雅氏病(CJD)是一种致命疾病,表现为快速进行性痴呆,大多数患者在临床发病后一年内死亡。CJD具有医源性传播的潜在风险,因为它可以在无症状的情况下在人体内温育数十年,然后才变得临床明显。在本综述中,我们通过检查所有形式的CJD(包括临床发病率和亚临床疾病患病率)的全球证据,寻求证据来了解当前的CJD对公共卫生的医源性风险。我们发现,尽管CJD(尤其是医源性CJD)很少见,但散发性CJD的发病率正在增加。已经观察到长达40年的潜伏期,并且现已证明所有基因型均对CJD敏感。临床医生和监视计划应保持对CJD的认识,以减轻其传播的未来发生率。意识与散发性CJD尤其相关,后者发生在老年人中,其临床表现可能类似于快速发展的痴呆症。
