Raccoon Dog DNA at Wuhan Market Not Conclusive Evidence for Covid-19 Origin, China Says

Chinese scientists have published a study in the journal Nature confirming the presence of animals susceptible to the coronavirus at the Huanan Seafood Wholesale Market in Wuhan in early 2020, where many of the earliest known Covid patients had worked or shopped. The study found DNA from raccoon dogs and other animals at the market, but the scientists said it remained unclear how the pandemic began. Many virologists believe the virus spilled into people from an illegally traded wild animal at the market, but the Chinese authors stressed uncertainty and raised the notion that the virus could have been ferried to the Wuhan market on packages of frozen food.

China's Delayed COVID-19 Data Disclosure Cost 3 Years of Political Dispute.

The release and analysis of viral and animal genetic material collected from the Huanan wet market in Wuhan, China, has revealed stronger evidence that raccoon dogs at the market were a possible animal reservoir of SARS-CoV-2, potentially infecting humans. If this evidence had been available three years ago, it could have reduced the political argy-bargy about less likely hypotheses of the pandemic's origins and better focused research attention. The delay in disclosing the data has made it difficult to track the animal sources and people who handled these animals, but open disclosure of sequence data is crucial for scientific investigation.

COVID-19 traced back to Wuhan raccoon dogs in genetic analysis.

Researchers from Europe, North America, and Australia have analyzed data gathered at the Huanan Seafood Wholesale Market in Wuhan, China, in January and February 2020, and published their findings in a report this week. The report provides the strongest evidence yet on the pandemic's natural origins and suggests that an animal, possibly a raccoon dog, may have started the pandemic. The genetic material of raccoon dogs found in the mix matters because it suggests that the virus may have jumped from animals to humans.

Raccoon dogs under scrutiny in COVID-19 origins investigation.

Genetic material collected at a Chinese market near where the first human cases of COVID-19 were identified show raccoon dog DNA commingled with the virus, adding evidence to the theory that the virus originated from animals, not from a lab, international experts say. Raccoon dogs are not closely related to raccoons but are members of the canid family, most closely related to foxes. They are often bred for their fur and sold for meat in animal markets across China. The mingling of DNA from the virus and from raccoon dogs is a strong indication that the mammals, reportedly sold live in the food market and known to be susceptible to coronaviruses, were infected.

Raccoon dogs may hold key to COVID-19 origins.

Genetic data from Wuhan's wet market has shown raccoon dog DNA blended with the COVID-19 virus, suggesting that the virus may have infected the animals. The data has not been formally reviewed nor published in a peer-reviewed journal, but international health experts say that this finding adds credence to the theory that the COVID-19 virus came from animals instead of a lab leak. WHO head Tedros Adhanom Ghebreyesus slammed China for not sharing the data earlier, and since the first COVID-19 death in Wuhan on January 11, 2020, the virus has killed 6,873,477 people worldwide.

Raccoon Dogs Implicated in Covid-19 Origins

The World Health Organization is investigating a possible link between raccoon dogs and the COVID-19 pandemic. Raccoon dogs are a wild dog native to East Asia, with fur markings and head shapes similar to those of raccoons. They were being sold at a seafood and meat market in Wuhan, China, where researchers found evidence of the coronavirus in January 2020. Raccoon dogs have been linked to other diseases in the past, and a recent study found that they carry 102 different viruses from 13 viral families, including four canine coronaviruses genetically similar to those found in humans. The study confirms the danger of live markets like the one in Wuhan, and experts warn that allowing them to flourish could lead to another outbreak and pandemic.

Raccoon Dogs at Wuhan Market Linked to COVID-19 Origins

New genetic analysis of SARS-CoV-2 viruses found at the Huanan animal market in Wuhan offers clues to the animal origin of the COVID-19 pandemic, including "molecular evidence" of animals like raccoon dogs at the market intermingled in swabs from the same spots that turned up the shedding from the virus itself in the market. However, the samples only indicate that both raccoon dogs and the virus were present at the market; it is not direct proof that the species was the carrier. The WHO has called for Chinese health authorities to release genetic sequences of SARS-CoV-2 that recently disappeared from an international database.

WHO Demands Transparency from China on COVID-19 Origins.

The World Health Organization (WHO) has accused Chinese officials of withholding research that may link Covid-19's origin to wild animals, asking why the data had not been made available three years ago and why it is now missing. The research suggests that illegally traded raccoon dogs infected humans at a Wuhan seafood market. The gene sequences were removed from a scientific database once the experts offered to collaborate on the analysis with their Chinese counterparts.

Raccoon Dogs Implicated in Covid-19 Origins.

Raccoon dogs, a monogamous and hibernating canid species related to foxes, have been in the spotlight as scientists reveal new data on the possible origins of the Covid-19 pandemic. Although they are farmed for their fur and sold for their meat in live animal markets, it is not proven that they are the source of the virus that causes Covid-19. Raccoon dogs are known to be vectors for other diseases, including rabies, and should not be kept as pets.

Raccoon Dogs at Wuhan Market Linked to Covid-19 Origins

New genetic data gathered from a live food market in Wuhan has linked Covid-19 with raccoon dogs, adding weight to the theory that infected animals sold at the site started the coronavirus pandemic. The discovery does not prove that raccoon dogs or other animals infected with Covid triggered the pandemic, but scientists believe it makes that more likely. The latest genetic data does not prove raccoon dogs or other mammals were infected with Covid and spread it at the market. If the animals were infected, they may have contracted the virus from infected humans.

Raccoon Dogs at Wuhan Market Linked to COVID-19 Pandemic Origins

Genetic data from swabs taken from the Huanan Seafood Wholesale Market in Wuhan, China, has linked the coronavirus with raccoon dogs for sale there, adding evidence to the case that the pandemic could have been ignited by an infected animal that was being dealt through the illegal wildlife trade. The genetic data was drawn from samples taken from the market in January 2020, shortly after Chinese authorities had shut down the market because of suspicions that it was linked to the outbreak of a new virus.

Raccoon Dogs Identified as Likely Origin of COVID-19 Pandemic.

Genetic data from a market in Wuhan, China, has been found linking the coronavirus with raccoon dogs for sale there, adding evidence to the case that the pandemic 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, but the analysis did establish that raccoon dogs deposited genetic signatures in the same place where genetic material from the virus was left, consistent with a scenario in which the virus had spilled into humans from a wild animal.

Genetic Analysis Points to Raccoon Dogs as Likely Origin of COVID-19 Pandemic.

A new genetic analysis of samples collected from a Wuhan seafood market suggests that raccoon dogs were likely carrying and shedding the virus near the end of 2019, making them the likely culprit for the origins of the COVID-19 pandemic. The research was conducted by an international team of virologists, genomicists, and evolutionary biologists, and though not definitive proof, it strongly indicates that animals at the market were infected.
