Genetic Samples From 2020 May Link Covid Start To Wuhan Market Animals
Swabs taken from the Chinese market in January 2020 provide the strongest evidence to date that the pandemic originated in animals, according to the genetic data analysis done by an international team of virus experts, first reported in The Atlantic.

The Strongest Evidence Yet That An Animal Started The Pandemic
This week, an international team of virologists, genomicists, and evolutionary biologists may have finally found crucial data to help fill that knowledge gap. A new analysis of genetic sequences collected from the market shows that raccoon dogs being illegally sold at the venue could have been carrying and possibly shedding the virus at the end of 2019. It’s some of the strongest support yet, experts told me, that the pandemic began when SARS-CoV-2 hopped from animals into humans, rather than in an accident among scientists experimenting with viruses.

New Data Links Pandemic’s Origins To Raccoon Dogs At Wuhan Market
An international team of virus experts said on Thursday that they had found genetic data from a market in Wuhan, China, linking the coronavirus with raccoon dogs for sale there, adding evidence to the case that the worst pandemic in a century could have been ignited by an infected animal that was being dealt through the illegal wildlife trade. ... The jumbling together of genetic material from the virus and the animal does not prove that a raccoon dog itself was infected. And even if a raccoon dog had been infected, it would not be clear that the animal had spread the virus to people. Another animal could have passed the virus to people, or someone infected with the virus could have spread the virus to a raccoon dog. (Mueller, 3/16)

Unearthed Genetic Sequences From China Market May Point To Animal Origin Of COVID-19
A scientific sleuth in France has identified previously undisclosed genetic data from a food market in Wuhan, China, that she and colleagues say support the theory that coronavirus-infected animals there triggered the COVID-19 pandemic. Several of the researchers presented their findings on Tuesday to the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), an expert group convened last year by the World Health Organization. “The data does point even further to a market origin,” says Kristian Andersen, an evolutionary biologist at Scripps Research who attended the meeting and is one of the scientists analyzing the new data. If so, the findings weaken the view of a vocal minority that a virology lab in Wuhan was the likely origin of SARS-CoV-2, perhaps when the coronavirus infected a lab worker, who spread it further.

Energy Department Briefs Senators On COVID-19 Origins
Department of Energy and intelligence community officials briefed members of the Senate Energy and Natural Resources Committee on classified information related to COVID-19’s origins Thursday but offered no definitive revelations, according to lawmakers. The briefing follows the news that the department now concludes with “low confidence” that the virus more likely originated in a lab in Wuhan, China, rather than through natural evolution.
