周一发表在杂志上的一项研究临床传染病由疾病控制和预防中心的研究人员进行的研究表明，这种新型病毒早在2019年12月中旬就已在美国出现。 6park.com
这一结论是基于来自华盛顿、俄勒冈州、加利福尼亚、康涅狄格州、爱荷华州、马萨诸塞州、密歇根州、罗得岛州和威斯康辛州的红十字会献血的结果得出的。
更具体地说，根据这项研究，在2019年12月13日至2020年1月17日收集的7389例献血中，有106例出现了SARS-CoV-2的证据，这是这种新型病毒的科学名称。


在来自华盛顿、俄勒冈州和加利福尼亚的39份血样中发现了抗病毒抗体，在其他6个州的67份样本中也发现了这种抗体。
研究人员称：“这些发现表明，SARS-CoV-2可能在2020年1月19日前被引入美国。”这些发现还“突出了献血作为进行SARS-CoV-2监测的来源的价值。”
其他研究也表明，这种病毒在美国出现的时间可能比人们最初想象的要早。具体来说，加州大学洛杉矶分校和华盛顿大学的研究人员在9月份发表的一项研究报告中说，这种新型病毒可能是在去年出现的。圣诞节前后的洛杉矶。

Coronavirus was present in US earlier than initially thought: Study
Though the first case of the coronaviruswasn’t identified in the U.S. until January, a new study suggests that the novel disease was present earlier in the country than first thought.
A study published Monday in the journal Clinical Infectious Diseases conducted by researchers with the Centers for Disease Control and Prevention suggests that the novel virus was present in the United States as early as mid-December 2019. 6park.com
The conclusion is based on blood donations from the Red Cross from nine states, including Washington, Oregon, California, Connecticut, Iowa, Massachusetts, Michigan, Rhode Island and Wisconsin.
More specifically, evidence of SARS-CoV-2, the scientific name for the novel virus, was present in 106 of the 7,389 blood donations, which were collected between Dec. 13, 2019, and Jan 17, 2020, according to the study.


Antibodies to the virus were found in 39 blood samples from Washington, Oregon and California, and they were found in 67 samples from the other six states.
“These findings suggest that SARS-CoV-2 may have been introduced into the United States prior to January 19, 2020,” the researchers stated. The findings also “highlight the value of blood donations as a source for conducting SARS-CoV-2 surveillance.”
Other studies have also suggested the virus may have been present in the U.S. earlier than first thought. Specifically, a study published in September conducted by researchers from the University of California, Los Angeles, and the University of Washington said that the novel virus may have been present last year in Los Angeles around Christmas.
