Actually, yes. For the first half of the pandemic, much of the medical community was unsure if COVID was airborne.

Note that "airborne" has a specific meaning in medical literature. Everyone agreed COVID could be transmitted in the air by respiratory droplets. But to be truly "airborne" means the virus could be aerosolized and float freely, without being attached to a larger droplet.

Both droplet-based and aerosolized/"airborne" spread allows viruses to be transmitted in the air. But a truly "airborne" virus can travel much farther.

It's the difference between needing 6 feet and 20 feet of distance to prevent spread.

(To put it bluntly, it's the difference between avoiding spittle, or avoiding the equivalent of cigarette smoke. Two very different threat models.)

This is the excuse hospitals used to send nurses into covid units with no or insufficient PPE when they got caught flat-footed having no stored supply. (and it was BS)
