Chinese scientists have published their long-awaited genetic analysis of the samples and swabs they collected in early 2020 from the Huanan Seafood Market, the initial epicenter of the pandemic.

In the study , published Wednesday in Nature, the authors acknowledge for the first time that wildlife susceptible to SARS-CoV-2 infection—including raccoon dogs —were present in the market amid the plethora of genetic traces from SARS-CoV-2 and humans. But, the overall analysis is flawed, indicating the presence of animals that were almost certainly not at the market, including giant pandas, chimpanzees, and Atlantic grey seals. The authors continued to downplay the potential that a virus spillover from wildlife to humans in the crowded market was the spark that ignited the pandemic. Instead, they repeatedly put forward, without evidence, hypotheses favored by Chinese officials, namely that the virus was carried into the market via humans or frozen foods, and the bustling venue became an amplifier site for infection.

Still, the publication of the data is momentous—and a long time coming. Though the samples were collected from January 1 to March 30 of 2020, a draft of the study and some of the data were only first released in a preprint two years later, in February 2022. The preprint reported that SARS-CoV-2 was abundant amid human genetic material from the samples, indicating that the virus was prevalent among people at the market before it was shuttered on the morning of January 1. The authors, led by scientists at China's Centers for Disease Control and Prevention (China CDC), noted that they had also tested some animals in the market—mostly rabbits, stray cats, and snakes—but all were negative for SARS-CoV-2.

A group of independent, international researchers has released its full analysis of newly uncovered metagenomic data collected by the Chinese Centers for Disease Control and Prevention in January and February of 2020. The data closely links SARS-CoV-2 to the genetic tracks of wild animals, particularly raccoon dogs , sold at the Huanan Wholesale Seafood Market in Wuhan, China, the early epicenter of the COVID-19 pandemic, the group's analysis says.

The full analysis provides additional, compelling evidence that the pandemic coronavirus made its leap to humans through a natural spillover, with a wild animal at the market acting as an intermediate host between the virus' natural reservoir in horseshoe bats and humans. It was authored by 19 scientists, led by Michael Worobey, an evolutionary biologist at the University of Arizona; Kristian Andersen, a virologist at the Scripps Research Institute in California; and Florence Débarre, a theoretician who specializes in evolutionary biology at France's national research agency, CNRS.

Prior to the release of the full analysis late Monday, information on the findings was only made public through media reports and statements from the World Health Organization, which was briefed on the analysis last week. But, the raw metagenomic data behind the analysis is still not publicly available. It was briefly posted on a public genetic database called the Global Initiative on Sharing Avian Influenza Data (GISAID) as recently as earlier this month, and the international researchers were able to download it during that window of availability. But, administrators for the database quickly removed the data after its discovery, saying the removal was at the request of the submitter, a researcher at China CDC.

Newly obtained genetic data from the Chinese Center for Disease Control and Prevention (China CDC) links the pandemic coronavirus SARS-CoV-2 to animals—specifically raccoon dogs—at the Huanan Seafood Wholesale Market in Wuhan, where the earliest COVID-19 cases centered, a group of independent scientists told the World Health Organization this week.

The genetic data came from environmental swabs collected at the market by China CDC in January of 2020. The existence of these swabs was previously known, as was the fact that they were positive for SARS-CoV-2 genetic material. But in late January of this year, scientists at China CDC uploaded—and then later removed—additional genetic data from these swabs to a public genetic database called GISAID, the WHO said. That additional data, which had not been previously disclosed, indicates that the SARS-CoV-2-positive swabs also contained genetic material from humans and animals, particularly large amounts of genetic material that closely matches that of raccoon dogs.

Raccoon dogs—foxlike animals whose faces closely resemble those of raccoons—are known to be susceptible to SARS-CoV-2 infection and were known to be sold at the market.

A New York-based nonprofit that has worked for decades to better understand and prevent the type of coronavirus pandemic now engulfing the world was abruptly stripped of its federal research funding in April. The White House specifically directed the National Institutes of Health to cancel the multimillion-dollar research grant after President Donald Trump promoted an unfounded conspiracy theory that the pandemic coronavirus, SARS-CoV-2, was released from a lab in Wuhan, China—a lab that collaborates with the nonprofit.

Now, the NIH has told the nonprofit, EcoHealth Alliance, that it may have its funding back—if it collects and hands over materials and information about the Chinese lab, which is part of the Wuhan Institute of Virology (WIV).

In a July 8 letter seen by The Wall Street Journal , the NIH laid out a list of seven criteria EcoHealth Alliance must fulfill in order to regain its peer-reviewed funding. The list includes:
