(CNN)-旨在阻止冠状病毒的旅行禁令根据美国疾病控制和预防中心的一项新的病例分析,从中国和欧洲到达美国已经太晚了。
2月2日,美国限制从中国旅行分析发现,3月13日来自欧洲,但到3月8日,新冠肺炎已经在纽约市的社区中传播,到3月15日,该病毒的社区传播已经广泛。
目前正在传播的病毒与在欧洲传播的病毒最接近,而不是在中国。美国总统唐纳德·特朗普(Donald Trump)一再指责中国没有阻止病毒传播到美国。
到特朗普政府对欧洲实施了旅行限制,根据这份报告,病毒的输入和疾病的社区传播已经在纽约市开始。在纽约市疫情开始时,检测是有限的,这使得未发现病例的人能够传播病毒。
特朗普一再指出,他的旅行禁令是他的政府有效应对这一流行病的证据,就在周二,他还声称“我们拯救了数百万人,甚至数百万人的生命”。
这项新的研究调查了纽约卫生和精神卫生部门在3月1日至20日之间收集的数据,这是美国大流行的早期。该署於三月八日宣布,市民可持续传播。
该部门检查了从有流感样症状的急诊室的人身上采集的标本。在检测的544份标本中,36份(6.6%)新冠状病毒呈阳性。
通过对样本进行额外的基因测序,这种病毒的毒株更像在欧洲传播的病毒,而不是在中国传播的病毒。报告称,这意味着这种新型冠状病毒很可能是通过欧洲或美国其他地方的旅行者传播到纽约的。
CNN在四月报道今年早些时候开始的两个单独的研究项目也表明了这一点,也表明病毒在该市传播的时间可能比想象的要早。
据约翰霍普金斯大学(JohnsHopkins University)的数据,目前美国有超过349.7万例确诊的冠状病毒病例,这种病毒已经夺走了逾13.7万名美国人的生命。
US travel bans came too late for New York City, CDC study finds – Boston News, Weather, Sports
(CNN) — Travel bans meant to stop the coronavirus from getting to the US from China and Europe came too late, according to a new analysis of cases from the US Centers for Disease Control and Prevention.
The US restricted travel from China on February 2 and from Europe on March 13, but by March 8, Covid-19 was already circulating among the community in New York City and, by March 15, community transmission of the virus was already widespread, the analysis found.
What was circulating most closely matched the strain of the virus circulating in Europe, not China, which President Donald Trump has repeatedly blamed for not preventing its spread to the US.
By the time the Trump administration had placed travel restrictions on Europe, the importation of the virus and the community spread of the disease had already started in New York City, according to the report. Testing was limited at the start of the epidemic in New York City, which allowed people with undetected cases to spread the virus.
Trump has repeatedly pointed to his travel bans as evidence that his administration has effectively responded to the pandemic, claiming as recently as Tuesday that “we saved millions, potentially millions of lives.”
The new study looked at data collected by the New York Department of Health and Mental Hygiene between March 1 and 20, the early days of the pandemic in the US. The department announced on March 8 that there was sustained community transmission.
The department examined specimens taken from people who went to the emergency room with flu-like symptoms. Of the 544 specimens tested, 36, or 6.6%, were positive for the novel coronavirus.
Doing additional genetic sequencing of the samples, the strain of the virus more closely resembled the one circulating in Europe, rather than the one circulating in China. That means that the novel coronavirus was likely introduced to New York through Europe or by travelers from other US locations, the report said.
CNN reported in April that two separate research projects started earlier this year also suggested as much, also suggesting the virus may have been circulating in the city earlier than thought.
There are currently more than 3,497,000 confirmed cases of coronavirus in the US, and the virus has claimed the lives of more than 137,000 Americans, according to data from Johns Hopkins University.
