2. 新的冠状病毒病(COVID-19)的病原体最初被称为 2019 新型冠状病毒(2019-nCoV)，但目前被命名为严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)，自 2020年 1 月 7 日首次发现病原体以来，COVID-19 已席卷全球。1 2020 年 3 月 11 日，世界卫生组织(世卫组织)宣布 COVID-19 升级为大流行病。截至 2020 年 12 月，已有 100 多万人因此丧生，令人遗憾的是，死亡人数仍在继续上升，尽管预计到2021 年最后一个季度，多种疫苗的持续部署将使死亡人数的上升大幅下降。虽然得病后康复的人越来越多，但越来越多的报告表明，一些康复者的健康会长期受损。
2. A novel coronavirus disease (COVID-19) has swept across the globe since its causative agent – first known as 2019 novel coronavirus (2019-nCoV), but currently designated as SARS-CoV-2 – was first identified on 7 January 2020.1 On 11 March 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic. As at December 2020, over a million lives had been lost, with the toll sadly continuing to rise, although the rise is expected to wane in significant measure by the last quarter of 2021, due to the ongoing deployment of several vaccines against the disease. Despite there currently being many more people recovering from the disease, there are increasing reports of long-term debilitating health effects for some of the recovered.
