Evidence for Wuhan lab-leak theory
An article in the respected Science journal on May 14, 2021 kick-started the surge in interest for the lab-leak theory.
Some 18 experts wrote in the journal that ‘we must take hypotheses about both natural and laboratory spillovers seriously until we have sufficient data’.
Later that month, a study by British Professor Angus Dalgleish and Norwegian scientist Dr Birger Sørensen claimed it had ‘prima facie evidence of retro-engineering in China’ for a year.
The study included accusations of ‘deliberate destruction, concealment or contamination of data’ at Chinese labs.
It followed statements from the WHO Director General, US and EU that greater clarity about the origins of this pandemic is necessary and feasible to achieve.
Previously, the theory had been dismissed as conspiracy by most experts, partly because of its association with President Donald Trump.
President Joe Biden in May 2021 ordered a full investigation into the origin of the pandemic virus and demanded scientists work out whether there is truth to the theory.
In December 2021, Harvard scientist Dr Alina Chan told the UK’s Science and Technology Select Committee that it is ‘reasonable’ to believe that Covid was genetically engineered in China.
She also said that the Chinese Communist Party’s cover-up of the initial outbreak in Wuhan two years ago and attempts to sabotage the World Health Organisation’s inquiry into the origins of the pandemic made the lab-leak theory likely.
The head of the World Health Organization insisted just a day earlier that the theory that Covid emerged from a Wuhan lab has not been ruled out — as he said China should help solve the mystery out of ‘respect’ for the dead.
The body’s director-general, Dr Tedros Adhanom Ghebreyesus, suggested that Beijing had not cooperated fully as he urged more ‘transparency’ in the continuing investigation.
And a senior Government source claimed in June 2022 that the WHO boss privately believes the pandemic kicked off following a leak from a Chinese lab.
In September 2022, leading medical journal the Lancet admitted the virus may have been leaked from a lab, including those in the US.
In October, a bombshell US Senate report concluded that the lab leak hypothesis was the most likely source of the pandemic.
Policymakers said there was ‘substantial’ evidence of an accident at a research facility — while evidence for a natural spillover is ‘still missing’.
The interim report concluded that China ‘s unwillingness to cooperate or open up the lab in question meant it ‘no longer deserves the benefit of the doubt’.
GOP members of the Senate Committee on Health Education, Labor and Pensions reviewed hundreds of studies into the origins of Covid and interviewed ‘several dozen’ experts over the past 15 months.
Evidence against the theory
A series of papers point to the virus evolving in animals before being transmitted to humans, in the same way as all other previously discovered coronaviruses.
The first study, published in Scientific Reports, showed some 47,000 wild animals from 38 species were sold across four markets in Wuhan between May 2017 and November 2019.
The authors, including Dr Chris Newman, an evolutionary ecologist at Oxford University, claimed the evidence showed the conditions for animal-to-human transmission were in place in Wuhan.
But they acknowledged there was no proof Sars-CoV-2 was present or originated in any of these animals.
A joint World Health Organization-China investigation also concluded it was ‘very likely’ the virus jumped from bats to humans via an as-yet-unknown intermediary animal.
And a June 2022 report by the WHO sets out that Covid most likely originated in bats before infecting humans.
A series of studies published in July appeared to trace the first cluster of cases back to one specific corner of the wet market, where animals known to harbor Covid including raccoon dogs, hedgehogs, rats and squirrels were kept.
Chinese scientists also found positive samples of an ancestral Covid strain on floors, counters and equipment in the market.
