NIH study offers new evidence of early SARS-CoV-2 infections in U.S.

Researchers analyze 24,000 blood samples and multiple antibody testing platforms to add to picture of COVID-19’s emergence.

www.nih.gov

key takeaways:
1. the virus that causes COVID-19, was present in the U.S. as far back as December 2019
2. analyzed more than 24,000 stored blood samples contributed by program participants across all 50 states between Jan. 2 and March 18, 2020. These participants were from outside the major urban hotspots of Seattle and New York City.(不是大城市，旅游带来的病毒可以排除，更可能是本地已经传播了）
3. The positive samples came as early as Jan. 7 from participants in Illinois, Massachusetts, Mississippi, Pennsylvania and Wisconsin. 大范围，多州发现了
4. All of Us worked with Quest Diagnostics to test samples on the Abbott Architect SARS-CoV-2 IgG ELISA and the EUROIMMUN SARS-CoV-2 ELISA (IgG) platforms. For a sample to be considered “positive” by the research team, it had to have positive results on both platforms, which target antibodies that bind to different parts of the virus. Both tests have emergency use authorization from the FDA.。

discussions:
1. 是不是应该再查早期的血液？ 既然查了1月2号的，那么没有理由不往前查
2.如果是从中国传过去的（多个outside the major urban hotspots），中国可能比11月份发生传播要早得多。
3.即使中国武汉地方官员没有隐瞒，一月份也已经迟了
4.老美自查是不是拉老共自查的一部分？
5. US intelligence found that three researchers at a lab in Wuhan, China, became sick with COVID-19 symptoms in November 2019 and sought hospital care。 是不是情报错了，应该three researchers不是11月份，而是更早？

So 9 out of 24,079. Assuming the blood sampling is representative (which it is likely not) and just multiplying up to all 330 M Americans. It would mean that 123,000 Americans would have had or had the virus at that point.
That sounds like a lot. (And it also sounds it would have been spreading for a while.)

我以为是什么重大发现呢

More evidence suggests COVID-19 was in US by Christmas 2019

A new analysis of blood samples from 24,000 Americans taken early last year is the latest and largest study to suggest that the new coronavirus popped up in the U.S. in December 2019 — weeks before cases were first recognized by health officials

It can be difficult to distinguish antibodies that neutralize SARS-CoV-2, the virus that causes COVID-19, from antibodies that fight other coronaviruses, including some that cause the common cold. Researchers in both the NIH and CDC studies used multiple types of tests to minimize false positive results, but some experts say it still is possible their 2019 positives were infections by other coronaviruses and not the pandemic strain.

One of the Illinois cases was infected as early as Christmas Eve, said Keri Althoff, an associate professor at the Johns Hopkins Bloomberg School of Public Health and the study's lead author.

武汉有多名传染案例瞒报， 在台湾医务人员提醒世卫组织后反而拉拢世卫组织狼狈为歼。

为了自己的GDP， 迟迟到春节才全国大封锁， 把病毒一直放到国外。造成世界一年半大停摆，

杀人狂魔

这2万4千样本的研究结果是什么？

这2万4千样本的研究结果是什么？

NIH研究的文章的结论在这里：

Antibodies to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in All of Us Research Program Participants, 2 January to 18 March 2020

Seven individuals had detectable severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G before the first confirmed cases in Illinois

Conclusions
Our findings indicate SARS-CoV-2 infections weeks prior to the first recognized cases in 5 US states.

美国自己的研究，不会NIH也跟WHO一样被中国收买了吧
