It was premature to rule out the possibility that the Coronavirus had escaped from a laboratory in Wuhan, says WHO chief Dr Tedros Ghebreyesus. This is in contrast to the WHO’s report in March which concluded that a lab leak was ‘extremely unlikely’. Admitting that gaining access to raw data was a challenge for the WHO team that went to China this year, Ghebreyesus asked China to be “open and transparent”. “I’m an immunologist, and I have worked in the lab, and lab accidents happen,” he said.
