A leading U.S. expert on influenza viruses has discovered that early sequencing of the coronavirus genome from a global database at the request of Chinese researchers.
Professor Jesse Bloom, who works at the Fred Hutchinson Cancer Research Center in Seattle, found a Wuhan University project that tracked 34 positive COVID-19 cases from January 2020, as well as 16 cases in early February where researchers are looking at diagnosing a SARS. -CoV-2 infection using a technique known as nanopore sequencing.
While the results of their researcher were published in March as a preliminary print, and in June after a peer review, the genomic sequences obtained during their research – and uploaded to the Sequence Read Archive maintained by the United States (SRA) within the National Institutes of Health – were taken through a process that could take place if SRA staff were asked to do so, according to The Telegraph.
But when I went to the Sequence Read Archive, I saw that the whole project was gone! (Note that as detailed below, it does not * imply * NIH malpractice. The Read Order policy allows submitters to remove by e-mail request.) (3 / n) pic.twitter.com/fEzOaVYZLZ

The sequences, retrieved from cloud storage and printed in a pre-print, described by experts as “the most important data” on the inception of Covid-19 in more than a year.
The support obtained is not supported even the “natural origin” or “lab leak” theory of the origin of the pandemic, according to scientists. However, this suggested that the virus was circulating in Wuhan sooner than previously thought, and perhaps point to responses to the origin of Sars-CoV-2-responses that will not only help end this pandemic but prevent the next.
The rise of the ranks also suggests that there is a lot of data from the early days of the epidemic that took place in China, and that can be obtained by investigators.
Bloom writes in a long Twitter thread: “Even if the events that led to the emergence of # SARSCoV2 in Wuhan are unclear (zoonosis vs lab accident), everyone agrees that the deep ancestors were coronaviruses from bats. So, we expect the former #SARS-CoV-2 the sequences may be more similar to those of coronavirus bats, and so on #SARS-CoV-2 continuing to evolve it may become more diverse from these ancestors. But that * is not the case! However, the early Huanan Seafood Market # SARSCoV2 viruses were much different from the bat coronaviruses than the # # SARSCoV2 viruses collected later in China and even in other countries. @lpipe @ras_nielsen give nice technical analysis to https://academic.oup.com/mbe/article/38/4/1537/6028993. ”– READ MORE
