Not long after came a 'scientists statement' signed by Ralph Baric that went further. Baric has worked at WIV on GoF experiments.
But how would he have known about the sickened WIV researchers? If it is him, either he was on site when it happened or someone gave him the information. If we can establish that he was not on site at the time, then either it wasn't him or someone gave him the information.
Like patient 0, who is source 0 in this case?
