BACKGROUND
Early Years' Settings (EYSs) provide childcare and education for children 0-5 years old. They remained fully open in England during the third National lockdown when other educational settings were only open for selected children. EYSs are generally considered to be low-risk settings for transmission of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2).
METHODS
An observational study describing a large outbreak of SARS CoV-2 within an EYS in Cambridgeshire, United Kingdom.
RESULTS
Overall 45 cases of SARS-CoV-2 were identified; 24 adults (71% of staff members) and 21 children (25% of nursery attendees). One case was identified as the alpha variant (B.1.1.7 [VOC-20-DEC-01]). One staff member became critically unwell.
CONCLUSIONS
Transmission of SARS-CoV-2 occurred quickly, with a high attack rate; likely a consequence of a variant with enhanced transmissibility and an inability of the setting to adhere to infection control measures.
背景
早期教育环境（EYS）为 0-5 岁儿童提供儿童保育和教育。在英格兰第三次全国封锁期间，其他教育环境仅对部分儿童开放，而 EYS 则保持全面开放。通常认为 EYS 是传播严重急性呼吸系统综合症冠状病毒 2（SARS-CoV-2）的低风险环境。
方法
一项描述在英国剑桥郡的一所 EYS 中 SARS-CoV-2 大规模爆发的观察性研究。
结果
共发现 45 例 SARS-CoV-2 病例；24 名成年人（占员工的 71%）和 21 名儿童（占托儿所出勤率的 25%）。1 例被确定为 alpha 变体（B.1.1.7 [VOC-20-DEC-01]）。1 名工作人员病情严重。
结论
SARS-CoV-2 传播迅速，发病率高；可能是由于具有更高传染性的变体以及该环境无法遵守感染控制措施所致。
