目的COVID-19在家庭中由儿童传播的可能性尚不清楚。在此，我们描述了儿童在COVID-19家庭传播中的作用。设计及设定回顾了韩国于2020年1月20日至4月6日报告的所有儿科COVID-19指数病例及其家庭成员。计算从儿童首发病例到家庭继发病例的继发发病率（SAR）。对儿童索引病例-家庭继发病例对的流行病学和临床结果进行了评估。结果共确定了107例儿童COVID-19指数病例及其248名家庭成员。确定了一对儿科指标-次要家庭病例，家庭SAR为0.5%（95% CI 0.0%至2.6%）。首个病例在国际旅行后在家自我隔离，待在自己的房间里，但与继发病例共用一张餐桌。结论在保持社会距离的情况下，从儿童到家庭成员的SAR较低，强调了严格的接触者追踪和早期隔离在限制家庭内传播方面的重要性。
Objective Transmissibility of COVID-19 by children in the household is not clear. Herein, we describe children's role in household transmission of COVID-19. Design and setting All paediatric COVID-19 index cases and their household members reported from 20 January to 6 April 2020 in South Korea were reviewed. The secondary attack rate (SAR) from child index case to household secondary case was calculated. Epidemiological and clinical findings of child index case-household secondary case pair was assessed. Results A total of 107 paediatric COVID-19 index cases and 248 of their household members were identified. One pair of paediatric index-secondary household case was identified, giving a household SAR of 0.5% (95% CI 0.0% to 2.6%). The index case was self-quarantined at home after international travel, stayed in her room, but shared a meal table with the secondary case. Conclusion The SAR from children to household members was low in the setting of social distancing, underscoring the importance of rigorous contact tracing and early isolation in limiting transmission within households.
