No. There is no law of physics that prevents viruses from floating around independent of moisture.
Please explain how that happens without an infected host getting them into the air.
Be specific.
Didn't say that now, did I?
Please explain in detail what happens to that virus when the droplet evaporates.
It ends up immobile, on whatever surface it fell onto.
Again, please explain how viruses fly around independently.
I'll wait.
