世卫组织报告:新冠病毒“极不可能”通过实验室事件传人

文章来源:admin    时间:2021-04-07

  世界卫生安排3月30日在日内瓦正式发布我国-世卫安排新冠病毒溯源联合研讨陈述。陈述以为,新冠病毒“或许至比较或许”从原始动物宿主直接传人,“比较或许至十分或许”经由中心宿主引进人类,“或许”经过冷链食物传人,“极不或许”经过实验室事情传人。   The virus that caused the COVID-19 pandemic is "extremely unlikely" to have originated in a lab, but most likely jumped from an animal to humans, according to a World Health Organization report released on Tuesday by a joint1 international and Chinese team probing the virus' origins. 世界卫生安排3月30日发布的陈述指出,引发新冠疫情的病毒“极不或许”源于实验室,最有或许是动物传达给人类。这份陈述是世界和我国团队联合展开病毒溯源研讨的成果。   The 120-page report said the virus most probably jumped from an animal, potentially a bat or pangolin, to an unknown intermediate animal host and then to humans. However, the path of transmission is still not known. 这份120页的陈述称,病毒最有或许来自动物,或许是蝙蝠或穿山甲,经由不知道中心宿主传达给人类。但是,传达途径仍然不清楚。   "There is no record of viruses closely related to SARS-CoV-2 in any laboratory before December 2019, or genomes that in combination could provide a SARS-CoV-2 genome," the report said. 陈述称:“在2019年12月之前,任何实验室都没有与新式冠状病毒密切相关的病毒记载,也没有能供给新冠病毒基因组的基因组合。”   "In view of the above, a laboratory origin of the pandemic was considered to be extremely unlikely." “综上所述,疫情极不或许源自实验室。”   The report said that the two most likely scenarios2 to explain the emergence3 of COVID-19 both involve the transmission of the virus from animals to humans. 陈述称,最或许说明新冠病毒来源的两个场景均与动物传人有关。   "So far, we have not been able to document any substantial transmission of SARS coronavirus in the months preceding the outbreak in December," Thea Fisher, a member of the international team, said at a news conference on the report on Tuesday. 世界团队成员西娅·费雪3月30日在该陈述的新闻发布会上表明:“迄今为止,咱们还未能记载下2019年12月疫情爆发前新冠病毒的任何本质性传达。”
