Tedros told reporters thatthe UN health agency based in Geneva is “asking actually China to be transparent,open and co-operate,especially on the information,raw data that we asked for at the early days of the pandemic”.
He said there had been a “premature push” to rule out the theory that the virus might have escaped from a Chinese government lab in Wuhan – undermining WHO’s own March report,which concluded that a laboratory leak was “extremely unlikely”.
“I was a lab technician myself,I’m an immunologist,and I have worked in the lab,and lab accidents happen,” Tedros said. “It’s common.”
In recent months,the idea that the pandemic started somehow in a laboratory – and perhaps involved an engineered virus – has gained traction,especially with US President Joe Bidenordering a review of US intelligence to assess the possibility in May.
China has struck back aggressively,arguing that attempts to link the origins of COVID-19 to a lab were politically motivated and suggesting that the virus might have started abroad. At WHO’s annual meeting of health ministers this year,China said that the future search for COVID-19’s origins should continue – in other countries.
Most scientists suspect that the coronavirus originated in bats,but the exact route by which it first jumped into people – via an intermediary animal or in some other way – has not yet been determined. It typically takes decades to narrow down the natural source of an animal virus like Ebola or SARS.
