According to the draft text of the WHO report on the source of the coronavirus, COVID-19 was probably transmitted to humans from bats through another animal.

The draft, obtained by the Associated Press, said it was “very unlikely” that the coronavirus would be produced in a laboratory.

The report’s findings were largely as expected and left many questions unanswered. In the WHO-China jointly participated study, the team recommended more studies in all areas except for the possibility of laboratory leakage.

The publication of the report was postponed several times.

The Associated Press’s draft report from a diplomat in Geneva also says there is a possibility of changes before publication.

WHO Director-General Tedros Adhanom Ghebreyesus said the report will be made public tomorrow after diplomats are informed.

Peter Ben Embarek, the expert who oversaw the WHO team’s visit to Wuhan, said on Friday that the report had been finalized and that the information had been verified and translated.

In their study of the source of the virus, the WHO team in Wuhan stressed that they had ruled out the possibility that COVID-19 was a laboratory product. It also noted the possibility that the virus could be transmitted through the frozen product chain.
