^It's airborne, Maw. Caught by inhaling aerosols, very fine particles hanging in the air, like smoke. Particularly in enclosed spaces^
So don’t we need to wash hands or use sanitiser any more?.
Not beyond the usual hygiene practices, no.
It was originally thought that the virus could be passed on through droplets expelled by coughing etc (they're much bigger than aerosols) contaminating surfaces, but researchers found that it was practically impossible to culture the virus to infective levels from 'contaminated' surfaces.
So all the sanitising of everything has been a bit superfluous really. Still, I expect the sanitizer manufacturers don't mind...
