The World Health Organization (WHO) issued a new report last Thursday fair (9) in which he reconsiders the possibility of the Covid virus-10 leaked from a laboratory in Wuhan, China. The hypothesis, which has already been rejected by the Organization, will now be investigated.

According to the document, the scientists said they “will remain open to any and all scientific evidence that becomes available in the future, to allow comprehensive testing of all hypotheses.” reasonable”.

However, the researchers run into obstacles imposed by the Chinese. “The Chinese government still refuses to share essential raw data and does not allow a thorough and necessary audit of the Wuhan laboratories,” said Jamie Metzl, a member of the WHO advisory group.

Before, the most vehemently defended thesis was that the SARS-CoV-2 virus had a zoonotic origin, meaning it spread between animals in a natural environment. In March of 2000, the WHO concluded, in partnership with China, that the disease probably passed from bats to humans.

“However, the precursor viruses that have been identified in bats are definitely not close enough to be the virus that spread among humans,” said Marietjie Venter, chair of the WHO team and a virologist at the University of Pretoria, South Africa, at a press conference last week.
