From the press release:
“The purpose of the analysis was to determine the origin of SARS-CoV-2, the virus that causes COVID-19. Beginning with a likelihood of 98.2% that it was a zoonotic jump from nature with only a 1.2% probability it was a laboratory escape, twenty-six different, independent facts and evidence were examined systematically. The final conclusion is that it is a 99.8% probability SARS-CoV-2 came from a laboratory and only a 0.2% likelihood it came from nature.”
