Compared to the leaked data final week, the report provides extra element about different animals current on the market, in addition to exhibiting that a few of the SARS-CoV-2 constructive environmental samples had extra animal than human genetic materials in them, which the researchers stated it was in step with the animals being contaminated.
WHO officers stated final week that the knowledge was not conclusive however did characterize a brand new lead into the investigation into COVID’s origins, and will have been shared instantly.
The UN company has beforehand stated all hypotheses for COVID-19’s origins stay on the desk, together with that the virus emerged from a high-security laboratory in Wuhan that research harmful pathogens.
China denies any such hyperlink. WHO has additionally stated that almost all proof factors in the direction of the virus coming from animals, most likely bats.
