Studies link COVID-19 to wildlife sales at Chinese market, find alternative scenarios extremely unlikely

Analyses based on locations and viral sequencing of early cases indicate the COVID-19 pandemic started in Wuhan's Huanan Seafood Wholesale Market, with two separate jumps from animals to humans.

[beijingren3]

The two studies provide evidence that COVID-19 originated via jumps from animals to humans at the Huanan market, likely following transmission to those animals from coronavirus-carrying bats in the wild or on farms in China. Moving forward, the researchers say scientists and public officials should seek better understanding of the wildlife trade in China and elsewhere and promote more comprehensive testing of live animals sold in markets to lower the risk of future pandemics.

Funding for the research was provided primarily by the National Institutes of Health and the National Science Foundation. For a full listing of funding sources, please see the research papers.

The Huanan Seafood Wholesale Market in Wuhan was the early epicenter of the COVID-19 pandemic

Abstract
Understanding how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in 2019 is critical to preventing zoonotic outbreaks before they become the next pandemic. The Huanan Seafood Wholesale Market in Wuhan, China, was identified as a likely source of cases in early reports but later this conclusion became controversial. We show the earliest known COVID-19 cases from December 2019, including those without reported direct links, were geographically centered on this market. We report that live SARS-CoV-2 susceptible mammals were sold at the market in late 2019 and, within the market, SARS-CoV-2-positive environmental samples were spatially associated with vendors selling live mammals. While there is insufficient evidence to define upstream events, and exact circumstances remain obscure, our analyses indicate that the emergence of SARS-CoV-2 occurred via the live wildlife trade in China, and show that the Huanan market was the epicenter of the COVID-19 pandemic.

The molecular epidemiology of multiple zoonotic origins of SARS-CoV-2

Abstract
Understanding the circumstances that lead to pandemics is important for their prevention. Here, we analyze the genomic diversity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) early in the coronavirus disease 2019 (COVID-19) pandemic. We show that SARS-CoV-2 genomic diversity before February 2020 likely comprised only two distinct viral lineages, denoted A and B. Phylodynamic rooting methods, coupled with epidemic simulations, reveal that these lineages were the result of at least two separate cross-species transmission events into humans. The first zoonotic transmission likely involved lineage B viruses around 18 November 2019 (23 October–8 December), while the separate introduction of lineage A likely occurred within weeks of this event. These findings indicate that it is unlikely that SARS-CoV-2 circulated widely in humans prior to November 2019 and define the narrow window between when SARS-CoV-2 first jumped into humans and when the first cases of COVID-19 were reported. As with other coronaviruses, SARS-CoV-2 emergence likely resulted from multiple zoonotic events.

这些发现表明，SARS-CoV-2 不太可能在 2019 年 11 月之前在人类中广泛传播...

然而，意大利2019年8-10月，美国2019年5月 已经流行过了。

武汉海鲜市场是武汉的首发并不假。但是武汉海鲜市场跟缅因州龙虾有联系。存在“电子烟”肺炎到武汉海鲜市场的链条和联系。而海鲜市场缅因州龙虾的摊主，又恰好是武汉海鲜市场的0号首发病人。。。

加上两篇文章的基金来自NIH和美国自然科学基金委，不难看出，这是来替美国实验室制造 洗涤脱罪的。

新冠没在缅因州而是在武汉爆发，再怎么转进都显得很苍白

不测就没有

[cellcycle1]

缅因州爆发的叫“电子烟”不明肺炎，没测基因序列。因为是美国专利上的基因序列，只能是不测就没有了。
如果测的话，那不就是给自己定罪了吗？美国可不傻。

你没知识，电子烟 有医患传染 ？

“电子烟”不明肺炎，为什么没从缅因传遍全美国，进而全世界？如果是同一种东西，为什么比新冠差这么多？
