Almost half of the confirmed COVID-19 cases detected so far in the United Kingdom are part of a large cluster of 13 British nationals who tested positive for SARS-CoV-2 in the UK, Spain, and France. Transmissions among this cluster occurred at a ski resort in France, and originated from a single infected traveller returning from a conference in Singapore where he acquired the virus. At least 21 individuals were exposed to the virus, tested, and quarantined, with 13 of those testing positive between the period of 6th February and 15th February. Here, all publicly available information about the primarily UK/France cluster is consolidated, providing a complete and accessible summary of the cases and their connections. Notable in this cluster are the number of individuals infected, the apparent absence of any severe illness among those infected, and a case of a “delayed positive” test during isolation after initially testing negative, at least 7 days after last possible contact.
迄今为止，在英国发现的 COVID-19 确诊病例中，有近一半属于一个大型集群的 13 名英国国民，他们在英国、西班牙和法国检测出 SARS-CoV-2 呈阳性。该集群中的传播发生在法国的一个滑雪胜地，源自一名从新加坡参加会议回来的受感染旅行者，他在那里感染了病毒。至少有 21 人接触了病毒，接受了检测并进行了隔离，其中 13 人在 2 月 6 日至 2 月 15 日期间检测呈阳性。在这里，将所有关于主要在英国/法国集群的公开信息进行了整合，提供了病例及其联系的完整和易于访问的摘要。在这个集群中，感染人数众多，感染人群中显然没有任何严重疾病，而且在隔离期间，至少在最后一次可能接触后 7 天，最初检测呈阴性后出现了一次“延迟阳性”检测。
