Spillover from animals or lab leak? WHO says Covid-19 origins still unknown as lack of data hampers four-year investigation
GENEVA, June 28 — All hypotheses on how the Covid-19 pandemic began remain open, the World Health Organization said yesterday, following an inconclusive four-year investigation that was hamstrung by crucial information being withheld. The global catastrophe killed an estimated 20 million people, according to the WHO, while shredding economies, crippling health systems and turning people's lives upside-down. The first cases were detected in Wuhan in China in late 2019, and understanding where the SARS-CoV-2 virus that causes Covid came from is key to preventing future pandemics. However, a lengthy investigation launched by the UN's health agency said that pending further data, the origin of Covid and how it first spread remains elusive. 'As things stand, all hypotheses must remain on the table, including zoonotic spillover and lab leak,' WHO chief Tedros Adhanom Ghebreyesus told a press conference, referring to the two main hypotheses as to how the pandemic began. Expert investigation An initial WHO-Chinese joint report in March 2021 concluded that the virus most likely jumped from bats to humans via an intermediate animal. It deemed a leak from Wuhan's virology laboratories — known for their research on coronaviruses — to be 'extremely unlikely'. However, that investigation faced harsh criticism for lacking transparency and access, and for not seriously evaluating the lab-leak theory. Tedros launched another investigation, setting up the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), comprising 27 international experts, in July 2021. Their 78-page report was published on Friday. It said the weight of available evidence suggests a spillover from animals — either directly from bats, or through an intermediate host. However, it could not conclude with certainty where and when this happened, nor whether the Wuhan wet market was where the virus first spilled over into humans. That said, the market 'appears to be the location for amplification of infection in humans', leading to widespread transmission. 'Evidence for widespread infections or cases in any other countries prior to December 2019 is lacking,' it added. While spillover was the best supported theory on the evidence currently available, 'until further requests for information are met, or more scientific data becomes available, the origins of SARS-CoV-2 and how it entered the human population will remain inconclusive,' SAGO chair Marietjie Venter said at the press conference. Lab leak theories 'could not be investigated or excluded', she said, because much of the needed information had not been made available. The experts requested unpublished information from other countries, notably Germany and the United States, but without success, she said. Earlier this week, one SAGO member resigned and three others asked for their names to be removed from the report. 'Crucial question' 'Over the past five years, we have learned a lot about Covid-19 but there is one crucial question about the pandemic that we have not yet answered: how it started,' Tedros said. '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. He said WHO has requested access to intelligence reports by governments around the world on the origins of Covid-19. US President Donald Trump's administration has officially embraced the lab leak theory. Moral imperative Tedros said finding out how Covid-19 started was a moral imperative for those who lost their lives in the pandemic and to prevent further outbreaks. He said the virus was continuing to evolve, take lives and leave people suffering with post-Covid conditions, or so-called long Covid. Tedros said the WHO is appealing to countries with information about the origins of Covid-19 to share information. SAGO said it would continue to evaluate any new, sound scientific evidence and update its findings accordingly. — AFP

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'.

World Health Organisation admits they STILL have no idea what caused Covid pandemic – but refuses to rule out lab leak
A LEADING theory that the Covid pandemic originated from a lab leak in China cannot be ruled out, the World Health Organisation said. A team of experts set up by the WHO in 2021 to investigate Covid's origins said 'all hypotheses remain on the table' - while also accusing Beijing of not giving up critical information. 7 7 7 The Scientific Advisory Group for the Origins of Novel Pathogens (Sago) said on Friday that most data suggests the idea that the virus jumped from animals to humans. This is the same conclusion the WHO came to in 2021. Watch the documentary in full on our YouTube channel here Their new report made the bombshell claim that a lab leak theory should "not be ruled out". But they added: "Nor can it be proven until more information is provided." Group chair Marietjie Venter said after three years of investigating, they were unable to come to a certain conclusion of the pandemic's origins. They blasted China for not releasing all necessary data to determine Covid's creation - despite hundreds of requests for genetic sequences and biosecurity information to the government. She Venter: "Therefore, this hypothesis could not be investigated or excluded. "It was deemed to be very speculative, based on political opinions and not backed up by science." Venter said the 27-member group could not reach a unanimous conclusion on Covid's origins, following one member's resignation earlier this week. Three other scientists also asked for their names to be removed from the new report. I was in Oval Office with Trump at start of pandemic - no one was closer to Chinese officials than me & I believe Covid was engineered in lab Covid-19 emerged just eight miles from the Wuhan Institute of Virology. Scientists there had been importing and manipulating bat coronaviruses and had been filmed handling animals with inadequate protection. Venter added that there was no evidence proving Covid was created in a lab, nor was there any indication it was spreading before December 2019 anywhere outside of China. She said: "Until more scientific data becomes available, the origins of how SARS-CoV-2 entered human populations will remain inconclusive." Beijing has consistently refused to release full details about the lab in Wuhan, despite repeated requests for information from multiple countries. 7 7 7 It comes after The Sun's explosive Covid lab leak documentary laid bare the mounting evidence and disturbing questions surrounding the virus's emergence in Wuhan - home to China's most secretive bio-research facility. In April, the US unveiled a bombshell new web page on the origins of Covid, blaming the Wuhan Institute of Virology for unleashing the killer virus. And in a fresh propaganda push, Beijing insisted "substantial evidence" showed Covid "might have emerged in the United States earlier than its officially-claimed timeline, and earlier than the outbreak in China". The document - titled Covid-19 Prevention, Control and Origins Tracing: China's Actions and Stance - was released via China's official Xinhua news agency. It unashamedly accused the US of "indifference and delayed actions" during the global Covid fight - and of scapegoating China to deflect from its own "mismanaged" response. It wrote: "The US has made China the primary scapegoat for its own mismanaged COVID-19 response." The report added that America was 'spreading misinformation' and wasted 'precious time China had secured for the global fight against the pandemic". It revived Beijing's long-standing claims that it shared information with the world in a "timely manner". The paper added: 'The US should not continue to 'pretend to be deaf and dumb', but should respond to the legitimate concerns of the international community.' In May Donald Trump banned all US funding for risky virus research in China and beyond, five years after Covid-19 upended the planet. The US President said in the Oval Office last month: 'I said that right from day one it leaked out — whether it was to the girlfriend or somebody else, [a] scientist walked outside to have lunch with the girlfriend or was together with a lot of people — but that's how it leaked out in my opinion." The Sun's investigation into the origins of Covid 'Smoking gun' docs show US scientists planned to make viruses in Wuhan with SAME features of Covid year before outbreak Pentagon was told SIX times that Covid was lab leak at start of pandemic – but buried the truth, ex-intel official says US government backed shock Wuhan lab plan to collect 500,000 viruses months before Covid… and KNEW it was dangerous Wuhan Covid 'lab leak' firm given $60m US taxpayer funding for MORE virus tests Covid was 'perfectly adapted' to infect humans when virus emerged in Wuhan which 'proves' lab leak Bombshell clues that 'prove' China hid Covid lab leak in 'cover up of the century worse than Watergate' Crumbling sewers, no PPE, & filthy cages – Inside 'chaotic & crowded' Wuhan labs which may have unleashed Covid Wuhan Covid 'lab leak' scientists were 'bitten by bats & sprayed with blood' China's OWN scientists discussed 'problems' with Wuhan lab days after Covid outbreak Secret memo shows how panicked China ordered labs to destroy Covid samples Wuhan lab chief 'ordered scientists not to talk about Covid origins ' in leaked email France 'warned Wuhan lab could be turned into a 'biological arsenal' by Chinese military four years before Covid 'leak'

WHO expert group fails to find a definitive answer for how COVID-19 began
An expert group charged by the World Health Organization to investigate how the COVID-19 pandemic started released its final report Friday, reaching an unsatisfying conclusion: Scientists still aren't sure how the worst health emergency in a century began. At a press briefing on Friday, Marietjie Venter, the group's chair, said that most scientific data supports the hypothesis that the new coronavirus jumped to humans from animals. That was also the conclusion drawn by the first WHO expert group that investigated the pandemic's origins in 2021, when scientists concluded the virus likely spread from bats to humans, via another intermediary animal. At the time, WHO said a lab leak was 'extremely unlikely.' Venter said that after more than three years of work, WHO's expert group was unable to get the necessary data to evaluate whether or not COVID-19 was the result of a lab accident, despite repeated requests for hundreds of genetic sequences and more detailed biosecurity information that were made to the Chinese government. '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.' She 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. Five years ago, we predicted how COVID-19 would change our world. Here's what we got right – and wrong Venter said there was no evidence to prove that COVID-19 had been manipulated in a lab, nor was there any indication that the virus had been spreading before December 2019 anywhere outside of China. 'Until more scientific data becomes available, the origins of how SARS-CoV-2 entered human populations will remain inconclusive,' Venter said, referring to the scientific name for the COVID-19 virus. WHO Director-General Tedros Adhanom Ghebreyesus said it was a 'moral imperative' to determine how COVID began, noting that the virus killed at least 20 million people, wiped at least US$10 trillion from the global economy and upended the lives of billions. Last year, the AP found that the Chinese government froze meaningful domestic and international efforts to trace the virus' origins in the first weeks of the outbreak in 2020 and that WHO itself may have missed early opportunities to investigate how COVID-19 began. U.S. President Donald Trump has long blamed the emergence of the coronavirus on a laboratory accident in China, while a U.S. intelligence analysis found there was insufficient evidence to prove the theory. Chinese officials have repeatedly dismissed the idea that the pandemic could have started in a lab, saying that the search for its origins 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 racoon dogs, civet cats and bamboo rats.

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.
