An unprecedented outbreak of pneumonia of unknown aetiology in Wuhan City, Hubei province in China emerged in December 2019. A novel coronavirus was identified as the causative agent and was subsequently termed COVID-19 by the World Health Organization (WHO). Considered a relative of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), COVID-19 is caused by a betacoronavirus named SARS-CoV-2 that affects the lower respiratory tract and manifests as pneumonia in humans. Despite rigorous global containment and quarantine efforts, the incidence of COVID-19 continues to rise, with 90,870 laboratory-confirmed cases and over 3,000 deaths worldwide. In response to this global outbreak, we summarise the current state of knowledge surrounding COVID-19.
2019 年 12 月，中国湖北省武汉市爆发了一场前所未有的不明原因肺炎疫情。一种新型冠状病毒被确定为病原体，随后被世界卫生组织（WHO）命名为 COVID-19。COVID-19 被认为是严重急性呼吸综合征（SARS）和中东呼吸综合征（MERS）的近亲，由一种名为 SARS-CoV-2 的β冠状病毒引起，主要影响下呼吸道，在人类中表现为肺炎。尽管全球采取了严格的遏制和隔离措施，但 COVID-19 的发病率仍在持续上升，全球已有 90870 例实验室确诊病例，超过 3000 人死亡。针对这一全球疫情爆发，我们对 COVID-19 的相关知识进行了总结。
