美国CDC在2019年12月13至1月17的7389个献血样本中测出至少106人已有新冠抗体，当时美国感染率就已达1.43%

美国CDC对2019年12月13日至2020年1月17日的7389人的献血样本进行了检测。结果测出至少106人已有新冠病毒抗体。说明当时美国新冠感染率至少已达1.43% (106/7389)，或者说，美国当时至少已有472万人（3.3亿x1.43%）感染了新冠病毒。

至于2019年12月13日以前的献血样本中有没有新冠抗体，则不得而知，估计美国不打算测，再测下去美国就是源头了。

 

Coronavirus could have been spreading in US as early as mid-December 2019, study suggests

From CNN Health’s Amanda Sealy

The novel coronavirus may have infected people in the United States as early as Dec. 13, 2019, according to a study published Monday in the journal Clinical Infectious Diseases.

The study, which was conducted by scientists at the US Centers for Disease Control and Prevention, analyzed blood donations collected by the American Red Cross from Dec. 13, 2019 through Jan. 17, 2020. 

The 7,389 samples, collected from nine states, were tested for SARS-CoV-2 reactive antibodies. SARS-CoV-2 is the scientific name for the coronavirus that causes Covid-19.

Of the samples tested, at least 106 were found to have antibodies for SARS-CoV-2, including ones collected from California, Oregon and Washington from Dec. 13 through Dec. 16, 2019.

• 想到巴西、西班牙发现去年早些时候的样本有病毒，更是扑朔迷离。所以，我觉得军运会应当是武汉疫情的触发器。 -米兰之夜- ♂ (0 bytes) () 12/01/2020 postreply 14:01:18
