Investigators at Wuhan Covid say China refused to give raw data on the first case to a team of World Health Organizations investigating how the pandemic began.
Investigators said the country’s failure to provide data could have complicated efforts to understand how the outbreak began.
The WHO team requested data on 174 live cases identified by China in the early stages of the outbreak in Wuhan in December 2019.
However, Australian infectious disease expert Dominique Dwyer told Reuters that the request was not met, along with requests for other cases, and only a summary was provided to his team.
Such raw data was known as a “line list,” he said.
It is usually anonymized, but includes details such as what questions were asked to individual patients, their answers, and how they were analyzed.
He told Reuters in a video call from Sydney, which was quarantining, that this was a “standard practice” for outbreak investigations.
Access to raw data was especially important, as only half of the 174 cases were exposed to the South China Market, the abandoned wholesale seafood center in Wuhan, where Covid-19 was first detected.
“That’s why we’ve been asking for it,” Dwire said.
“I couldn’t comment on why it didn’t happen. It’s political, it’s time, it’s difficult … but I don’t know if there’s any other reason why the data isn’t available.
Access to raw data “standard practices”
WHO said a summary of the team’s findings could be released as early as next week.
Professor Dwire of Australia was one of 10 scientists who visited China on January 14th. World Health Organization mission We are investigating a virus that has killed 2.3 million people worldwide.
Professor Dwire WHO’s controversial findings confused by claiming that the virus DID started in China, And maintain the theory that the virus was transmitted from bats to humans.
This is in contrast to the claim of Dr. Peter Ben Enbarek, WHO research team leader. Imports of frozen foods may have been involved in the first outbreak.
Anger grows after WHO is accused of “plastering” It turns out that Covid didn’t come from the Wuhan fresh market, but from a lab leak.
Both proposals that the virus may have originally infected humans at the Huanan Seafood Market or escaped from the Wuhan Institute of Virology (WIV) were thrown at a long joint press conference on Tuesday.
However, microbiologist and infectious disease expert Professor Dwire argued that the source of the virus was likely to be a previously suspected bat.
“The evidence that it started elsewhere in the world is actually very limited. There is some evidence, but it’s not very good,” he said in Australia. Nine news..
“We know other viruses that are closely related [Covid-19] Present in bats. We know that in 2003 other viruses like MERS and SARS also came from bats.
“Currently, these bats, of course, do not respect borders, so they live not only in China, but in other parts of Southeast Asia, and in fact, elsewhere in the world.”
He said the virus is likely to infect humans as food through the traditional Chinese animal fresh market after infecting intermediate animals such as pangolins and cats.
“I think the Wuhan market explosion was a truly amplified event. The virus was probably prevalent among the people of the community for weeks,” he said.
Experts at a press conference on Tuesday admitted that they “do not know” the exact role of Wuhan’s South China seafood wholesale market in the origin of the virus.
While the series of incidents was market-related, authorities also found the incident among people unrelated to the market.
Wuhan Market “Amplification Event”
As initially suggested in the first study, it was suggested that the virus may have come from elsewhere and did not jump from animals to humans on the market.
Unpublished data suggest that a sample of SARS-CoV-2 was discovered weeks before the first reported case in Wuhan at the end of December 2019.
Professor Dwyer’s hypothesis claims that the case spread in Wuhan in November or perhaps a few weeks earlier, but they have not been reported by Chinese authorities.
“I also know that the Chinese reported that the people who went to the hospital were really ill, but I found that there were many other common infections among healthy people. Therefore, there must have been far more cases in December than that. Identified, “he said.
“Clearly, there’s a lot of work to do,” Dwyer added, admitting that “many of these outbreaks take years to resolve.”
In the aftermath of the first outbreak, Beijing officials sought to conceal the surge in deaths in Hubei by silencing those who tried to warn about the deadly virus.
Dr. Li Wenliang of Wuhan died in February 2020 after whispering a mysterious new coronavirus in December 2019 and getting the virus from a patient.
When asked if there was hostility between the WHO team and its Chinese host, Professor Dwire sometimes had “discussion” with Chinese respondents about the interpretation and importance of the data, and in such a survey ” “Nature.”
Discussion with Chinese counterparts
“We may be talking about the cold chain, and they may be more solid about what the data shows than what we might have been, but that’s natural.
“I don’t know if there is political pressure to have different opinions. It may, but it’s hard to know.”
Cold chains refer to the transportation and trading of frozen foods.
“I think the Chinese have different emphasis on what is important and what they want to say, at least from a political point of view,” he said.
However, at a press conference, Dr. Embarek upheld Beijing’s claim that there was no evidence of infection “in Wuhan or elsewhere” in China before December 2019-the virus was global months earlier. Despite multiple studies suggesting that it was prevalent in China.
Dr. Embarek outlined the results of the team’s one-month research trip and said the team was unable to identify where the virus came from or how the virus first invaded humans.

After a press conference on Tuesday, Defense Commission Rep. Tobias Ellwood told Sun Online: “This is a complete whitewash.
“Given the global economic devastation and deaths caused by this pandemic, the country responsible for the outbreak should never be allowed to interfere with international investigations for 12 months.”
