I think you have their position backwards. They originally agreed and said "Covid is not airborne", now they disagree. See the links in my other comment.
Correct, I accidentally reversed it. The point of my comment was that there was a period where the WHO said one thing and the CDC said another and they were mutually exclusive. These were the two most prominent health authorities, and there were many more that changed their stances on different days.
What is the single source of truth here? People were banned and deplatformed from social media for "spreading misinformation about COVID".
Quite early on there were indications it was airborne. I distinctly remember a group of researchers making a stink that the CDC wasn’t changing their position in it.
Honestly, I’m a bit amazed that isn’t something we can easily test. I’m no biologist but couldn’t we just take people sick with COVID in a room and have them breathe/talk/whatever with the equivalent of Petri dishes at differing distances?
