And some other regulars on this forum could add to the list of how virus can be spread, I'm sure.

I don't know about that being the most common way that viruses are spread, but it's certainly possible. I haven't seen an aphid on my lilies for years, but I do see an occasional leaf hopper that could surely do the job.

Absolutely. It's all a matter of degree, and doesn't just depend on distance.
