新京报快讯(记者 陈沁涵)世界卫生组织总干事谭德塞2月11日宣布,将新型冠状病毒感染的肺炎命名为“COVID-19”(Corona Virus Disease 2019)。与此同时,国际病毒分类委员会声明,将新型冠状病毒命名为“SARS-CoV-2”(Severe Acute Respiratory Syndrome Coronavirus 2)。

疾病命名:COVID-19

根据世卫组织新闻发布会视频,对于疾病的正式命名,谭德塞11日在会上解释,CO代表冠状(Cornona), VI代表病毒(Virus), D代表疾病(Disease), 19则因为疾病爆发于2019年。

谭德塞表示,这样命名是为了避免与地理位置、某种动物、个人或群体相关联。拥有一个正式名称很重要,可以防止名称使用不准确或是“污名化”。“这(COVID-19的命名)也为我们提供了一种标准格式,可用于将来任何冠状病毒的暴发。”

根据世卫组织网站信息,2015年5月,世卫组织公布了新发现疾病命名指导原则,鼓励研究人员、卫生官员与媒体使用中性的、一般的术语代替人物、地点、动物、食物和职业等命名疾病。之所以发布指导原则,是因为科学界以外的人员往往会给疾病取俗名,一旦通过互联网和社会媒体确立通常情况下使用的疾病名称,即使所用名称不够恰当也很难做出更改。

此前,国家卫健委将新型冠状病毒感染的肺炎暂命名为“新型冠状病毒肺炎”,简称“新冠肺炎”,英文简称“NCP”。现在,世卫组织宣布命名,意味着NCP将不作为正式名称使用。

病毒命名:SARS-CoV-2

国际病毒分类委员会在生物学论文预印平台bioRxiv上发表声明,其委员会的冠状病毒研究小组(CSG)此前将新型冠状病毒暂命名为“2019- nCoV”,根据系统学、分类学和惯例,CSG现正式将该病毒命名为“SARS-CoV-2”,并认定这种病毒是SARS冠状病毒的姊妹病毒。

CSG建议,为了增进交流,对于此次病毒分离出来的单独病毒株,命名可依照“SARS-CoV-2/分离物/宿主/日期/地点”的惯例。

声明指出,人类感染SARS-CoV-2的临床表现尚待确认,SARS-CoV和SARS-CoV-2的人畜共患病传播,凸显了对整个病毒类群进行研究的需要。

国际病毒分类委员会由微生物学会国际联盟的病毒学部组建,负责给病毒分类与命名,委员会已制定了一套病毒的通用分类方案,其成员都是被公认的病毒学专家。国际病毒分类委员会希望,新名称除了有助公众了解病毒,也让研究人员不用浪费时间和产生误会,可以专注抗疫。

外界有声音指出新病毒的命名花了太长时间,对此,约翰斯·霍普金斯卫生安全中心的助理教授克里斯蒂尔·沃森对BBC表示:“为新病毒命名时常会有所延误,这是可以理解的,因为重点应放在公共卫生措施上。”

  20. Thanks for the tips on credit repair on all of this blog. What I would advice people is to give up the mentality that they can buy now and pay later. As a society we tend to do this for many things. This includes vacations, furniture, and items we want. However, you need to separate your wants from all the needs. While you are working to improve your credit score you have to make some sacrifices. For example you can shop online to save money or you can go to second hand stores instead of expensive department stores for clothing.
