Covid origins investigation inconclusive, says WHO
A long-running World Health Organization investigation into the origins of Covid-19 has been unable to conclude where the virus came from because of a refusal to share information by China and intelligence agencies. An independent panel found that the most likely scientific explanation for the emergence of Covid-19 was direct transmission from bats to humans, or via an intermediary animal sold at the Wuhan wet market where the first cases emerged in December 2019, the WHO announced on Friday. 'Most scientific data and accessible published scientific evidence currently supports this hypothesis, however [we] are not currently able to conclude when, where and how Sars Cov-2 entered the human population,' Dr Marietjie Venter, Chair The Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), told a press conference. Dr Venter added that the Wuhan Huanan seafood market had played a 'significant role' in the spread of the virus, and that 60 per cent of early cases could conclusively be traced back to the site. She added that no widespread human or animal cases had been recorded anywhere else before December 2019. The pandemic killed an estimated 20 million people while shredding economies and crippling health systems, according to the WHO. Understanding its origins is seen as key to preventing future pandemics. The panel was unable to rule out the possibility that the virus emerged from a laboratory leak in Wuhan due to a lack of cooperation from Chinese authorities and other governments who had been unwilling to share intelligence reports, the health agency said. 'Much of the information needed to investigate this hypothesis has not been made available to WHO or SAGO, despite repeated requests to the government of China,' said Dr Tedros Ghebreyesus, the WHO's Director General. 'Despite our repeated requests, China hasn't provided hundreds of viral sequences from individuals with Covid-19 early in the pandemic, more detailed information on animals sold at markets in Wuhan, and information on work done and biosafety conditions at laboratories in Wuhan,' he said. The CIA said in January that Covid-19 was 'more likely' to have leaked from the Wuhan Institute of Virology, a highly secure laboratory located in the heart of the city where the first cases of Covid-19 were recorded, than to have come from animals. Germany's foreign intelligence service, the BND, believes there is an 80-90 per cent chance that coronavirus accidentally leaked from a Chinese lab, German media reported earlier this year. Dr Tedros said: 'WHO is also aware of intelligence reports performed by other governments around the world on the origins of Covid-19, we have also requested access to those reports [....] and have not had access to [them] or their underlying data.' As well as the lab leak and zoonotic spillover explanations, the committee also investigated two other hypotheses. One, which was promoted by Beijing in the early days of the pandemic, is the claim that Covid-19 was transmitted via frozen food products imported into China. Dr Venter said that 'more data is required to prove this hypothesis'. A fourth theory – popular on social media – is that the pandemic was the result of a deliberate laboratory manipulation of the virus. 'SAGO analysed the genomic structure of the virus and did not find scientific evidence supporting this hypothesis. There's also evidence that these mutations and recombinations occur in nature,' Dr Venter said. The WHO's efforts to uncover the origins of Covid have long been shrouded in doubt, largely because of China's refusal to share information with investigators. After four years of investigation, 'all hypotheses remain on the table,' said Dr Tedros. He added that the WHO continued to appeal to Beijing and other countries with information about the origins of Covid-19 to share the information openly, in the interests of protecting the world from future pandemics. The full SAGO report was published on Friday. Its authors concluded that 'although evidence exists that has improved our understanding of the early and subsequent evolution of the virus in humans and animals, significant data gaps remain which preclude SAGO from concluding with certainty how SARS-CoV-2 initially entered the human population'. The panel urged China and the global scientific community to 'prioritise further work on understanding the origins of Covid-19 and for all countries to comprehensively study future emergences of unknown pathogens'.

WHO says probe into COVID-19 virus origin still ongoing
The World Health Organisation says efforts to determine the origins of SARS-CoV-2, the virus that caused the COVID-19 pandemic, are still ongoing and incomplete. WHO chief Tedros Adhanom Ghebreyesus said "all hypotheses must remain on the table" to determine the cause of the virus, also known as SARS-CoV-2, after an expert group investigating its origins reached an unsatisfying conclusion in its final report released on Friday. "As things stand, all hypotheses must remain on the table, including zoonotic spillover and lab leak," Dr Tedros told a press conference, referring to the two main hypotheses as to how the pandemic began. The WHO Scientific Advisory Group reported progress in understanding COVID-19's origins but noted that critical information required to fully assess all hypotheses remains unavailable. The agency said it requested China share hundreds of genetic sequences from COVID-19 patients early in the pandemic, detailed information on animals sold at Wuhan markets, and details on research and biosafety conditions at Wuhan laboratories. WHO said China has not yet shared the information. China's foreign ministry did not immediately respond to a Reuters request for comment. The first cases were detected in Wuhan in China in late 2019, and understanding where the Sars-CoV-2 virus that causes COVID-19 came from is key to preventing future pandemics. In 2021, Dr Tedros launched the WHO Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), a panel of 27 independent international experts. Marietjie Venter, the group's chair, said on Friday that most scientific data supports the hypothesis that the new coronavirus jumped to humans from animals. But she added that after more than three years of work, SAGO was unable to get the necessary data to evaluate whether or not COVID was the result of a lab accident. "Therefore, this hypothesis could not be investigated or excluded," she said. "It was deemed to be very speculative, based on political opinions and not backed up by science." Venter said that the 27-member group did not reach a consensus; one member resigned earlier this week and three others asked for their names to be removed from the report. Agencies

New WHO report fails to rule out COVID-19 lab leak origin as China continues to impede investigation
A World Health Organization (WHO) scientific advisory group on Friday released a report on the origins of COVID-19, concluding that available evidence suggests the deadly pandemic was caused by "zoonotic spillover," either directly from bats or through an intermediate host. The report from the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), which claims to be a panel of 27 independent, international, multidisciplinary experts, said that much of the information needed to fully evaluate all hypotheses has not been provided. However, still citing a believed cause, WHO Director-General Tedros Adhanom Ghebreyesus said that "all hypotheses must remain on the table, including zoonotic spillover and lab leak." As the Wall Street Journal previously reported, the WHO's COVID-19 origin findings come amid a pattern of suspicious activity. The WHO traveled to China in early 2021 with British zoologist Dr. Peter Daszak, who was disbarred last year from doing work for the U.S. Department of Health and Human Services and is accused of using American taxpayer dollars to fund gain-of-function research at the bat lab in Wuhan, China. Once at the Wuhan lab, Daszak and others were allegedly blocked from doing any of the research necessary to investigate. As noted by the White House when highlighting a report from the Select Subcommittee on the Coronavirus Pandemic, "The Proximal Origin of SARS-CoV-2" publication — which was used repeatedly by public health officials and the media to discredit the lab leak theory — was prompted by Dr. [Anthony] Fauci to push the preferred narrative that COVID-19 originated in nature. The WHO said it had requested that China share hundreds of genetic sequences from individuals with COVID-19 early in the pandemic, more detailed information about the animals sold at markets in Wuhan, and information on work done and biosafety conditions at laboratories in Wuhan. To date, China has not shared this information either with SAGO or the WHO. "I thank each of the 27 members of SAGO for dedicating their time and expertise to this very important scientific undertaking over more than three years," Ghebreyesus wrote in a statement. "… We continue to appeal to China and any other country that has information about the origins of COVID-19 to share that information openly, in the interests of protecting the world from future pandemics." SAGO published its initial findings and recommendations in a report on June 9, 2022. The most recent report updates the evaluation based on peer-reviewed papers and reviews, as well as available unpublished information and field studies, interviews and other reports, including audit findings, government reports and intelligence reports. Those part of SAGO convened in various formats 52 times, conducted briefings with researchers, academics, journalists and others, according to the WHO. "As the report says, this is not solely a scientific endeavor, it is a moral and ethical imperative," Marietjie Venter, chair of the group, wrote in a statement. "Understanding the origins of SARS-CoV-2 and how it sparked a pandemic is needed to help prevent future pandemics, save lives and livelihoods, and reduce global suffering." "The work to understand the origins of SARS-CoV-2 remains unfinished," the WHO wrote in a statement. "WHO welcomes any further evidence on the origins of COVID-19, and SAGO remains committed to reviewing any new information should it become available."

COVID-19 origin still ‘inconclusive' after years-long WHO study
The World Health Organization (WHO) says efforts to uncover the origin of the COVID-19 pandemic are still ongoing and incomplete, as critical information has 'not been provided'. WHO chief Tedros Adhanom Ghebreyesus said 'all hypotheses must remain on the table' to determine the cause of the virus, also known as SARS-CoV-2, after an expert group investigating its origins reached an unsatisfying conclusion in its final report released on Friday. 'We continue to appeal to China and any other country that has information about the origins of COVID-19 to share that information openly, in the interests of protecting the world from future pandemics,' Tedros said. The global pandemic, which began in 2020, killed millions worldwide, with countries enforcing lockdowns in an attempt to stop the spread of the virus. With the first cases detected in Wuhan, China, in late 2019, information from the country is seen as key to preventing future pandemics. In 2021, Tedros launched the WHO Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), a panel of 27 independent international experts. Marietjie Venter, the group's chair, said on Friday that most scientific data supports the hypothesis that the new coronavirus jumped to humans from animals. But she added that after more than three years of work, SAGO was unable to get the necessary data to evaluate whether or not COVID was the result of a lab accident, despite repeated requests for detailed information made to the Chinese government. 'Therefore, this hypothesis could not be investigated or excluded,' she said, however adding, 'It was deemed to be very speculative, based on political opinions and not backed up by science.' Venter also said there was no evidence to prove that COVID had been manipulated in a lab, nor was there any indication that the virus had been spreading before December 2019 anywhere outside of China. 'Remains inconclusive' In 2021, a group of experts from the WHO first travelled to Wuhan to examine the origins of the virus with their Chinese counterparts. By March of that year, their joint report found that the most likely hypothesis was from bats to humans via an intermediate animal. They said at the time that a lab leak was 'extremely unlikely'. However, that investigation faced backlash for lacking transparency and access, and not taking the lab-leak theory seriously. After that, SAGO was launched. According to the SAGO report, 'the weight of available evidence … suggests zoonotic [a disease spread between animals to humans] spillover … either directly from bats or through an intermediate host'. 'Until more scientific data becomes available, the origins of how SARS-CoV-2 entered human populations will remain inconclusive,' Venter said. 'Understanding the origins of SARS-CoV-2 and how it sparked a pandemic is needed to help prevent future pandemics, save lives and livelihoods, and reduce global suffering,' she added. Tedros said it was a 'moral imperative' to determine how COVID began, noting that the virus killed at least 20 million people, wiped at least $10tn from the global economy and upended the lives of billions.

WHO still seeking COVID-19 origin, says all scenarios ‘remain on the table'
The World Health Organization says its probe into the origins of the SARS-CoV-2 virus, which caused the COVID-19 pandemic, is still ongoing, and despite a three-year investigation, has yet to find the exact cause. 'As things stand, all hypotheses must remain on the table, including zoonotic spillover and lab leak,' WHO director-general Tedros Adhanom Ghebreyesus said during a press briefing Friday. His comments came after a report published Friday from the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), which said 'available evidence' supports the hypothesis that the coronavirus jumped from animals to humans, likely from bats 'or through an intermediate host,' through a process called zoonotic spillover. SAGO is a panel of 27 independent, international, multidisciplinary experts formed by the World Health Organization to advise on technical and scientific considerations regarding emerging and re-emerging pathogens, like COVID-19. Story continues below advertisement 'While most available and accessible published scientific evidence supports hypothesis #1, zoonotic transmission from animals, possibly from bats or an intermediate host to humans, SAGO is not currently able to conclude exactly when, where and how SARS-CoV-2 first entered the human population,' the report reads. It notes the closest known 'precursor strains' were identified in bats in China and the Lao People's Democratic Republic, but says the strains are too distantly related to the virus to be the direct source of the pandemic. The report notes that some of the difficulty in determining a cause is due to China not having shared certain information, which also has made it difficult to examine the second hypothesis suggesting an accidental lab leak. The WHO requested the country share hundreds of genetic sequences from individuals with COVID-19 early in the pandemic, as well as more detailed information about the animals sold at markets in Wuhan, and information on work done and biosafety conditions at laboratories in Wuhan.

Marietjie Venter, the chair of the group, said on Friday during a press briefing that without the necessary data, it could not evaluate if the virus was the result of a lab accident. 'Therefore, this hypothesis could not be investigated or excluded,' Venter said. 'It was deemed to be very speculative, based on political opinions and not backed up by science.' Story continues below advertisement That hypothesis is one U.S. President Donald Trump has repeatedly suggested as the cause, though a U.S. intelligence analysis found there was insufficient evidence to prove the theory. 1:57 WHO says COVID-19 origins still under investigation despite recent reports Two other hypotheses were also provided in the report, the first being the introduction of the virus into animal markets via 'cold chain processes' and subsequent infection in humans through contact with products sold at the market. Venter said no added evidence has become available to support the hypothesis and more data is needed to prove it. The last hypothesis, involving deliberate manipulation of the virus in a laboratory, followed by a biosafety breach, remains unsupported, with Venter noting that SAGO examined the genome structure of the virus and any related publications and reports but found no evidence to support it. All four hypotheses will be re-evaluated if further information becomes available, but Venter said the first related to zoonotic spillover is considered the supported hypothesis. Story continues below advertisement 'Until more scientific data becomes available, the origins of how SARS-CoV-2 entered human populations will remain inconclusive,' she said. Ghebreyesus recognized during the briefing that the task of investigating the cause was difficult, and told reporters that members of SAGO have not all agreed on everything, which is 'to be expected.' He said earlier this week that one member of the team resigned and three others asked for their names to be removed from the report. Ghebreyesus went on to express concerns that China had not provided further information and encouraged it, as well as other governments he said have conducted COVID-19 investigations, to provide this data. Last year, The Associated Press found that the Chinese government had frozen meaningful domestic and international efforts to trace the virus's origins in the first weeks of the outbreak in 2020, and that the WHO may have missed early opportunities to investigate how the pandemic began. Chinese officials have repeatedly dismissed the idea the pandemic could have started in a lab, saying the search should be conducted in other countries. Last September, researchers zeroed in on a short list of animals they think might have spread COVID-19 to humans, including raccoon dogs, civet cats and bamboo rats. — with files from The Associated Press
