"Virus particles" do not float free in the air to spread disease. It's usually mostly salt water aerosols with a few virus particles in them.

  Is that known? I don’t think it’s been conclusively decided whether or not the virus spreads via aerosolized droplets or if it’s truly airborne.

    It is known fairly well in the context of SARS-CoV-2, but other viruses may have different distributions.

    I thought they became airborne by being expelled in a droplet ang the droplet evaporating.

  They certainly can free-float, generally speaking, but SARS-CoV-2 in particular is indeed known to be mostly in droplets and aerosols. Personally, I’d caution not to over-generalize this fact.

  The smaller a droplet is, the quicker it evaporates due to increasing surface area ratio.
