After its team ruled out in 2021 the possibility that the coronavirus responsible for the pandemic that brought the world to its knees had accidentally come out of a lab in China, the World Health Organization returns to this old issue with a new perspective.
A team of experts set up to help investigate the origins of the coronavirus pandemic has concluded that further research is needed to determine how COVID-19 started, including a more detailed analysis of the possibility of a laboratory accident.
“Key pieces of data are still missing to explain how the pandemic started. “Our group remains open to any scientific evidence that will be made available in the future to allow comprehensive verification of all reasonable hypotheses.” declared WHO.
This stance marks a significant reversal of the UN Health Agency’s initial assessment of the origin of the pandemic. The WHO concluded last year that it was “extremely unlikely” that COVID-19 would have spread to humans from the laboratory.
Many scientists suspect that the coronavirus has been transmitted to humans by bats, through other animals. Identifying the source of such diseases in animals usually takes years.
It took about 15 years for scientists to find the species of bats that were naturally reserved for SARS considered cousins of COVID-19.
But the WHO expert group also noted that, given that laboratory accidents have caused several epidemics in the past, this theory, highly politicized, is not accepted by China and has been widely trumpeted by former US President Donald Trump can not be dismissed.
