Question About Spreading Virus

[DebsC]

Here is a paragraph I read this morning and I want to know your opinions about the validity of it.

If these two virus are only spread through human manipulation such as potting, dividing and such. Could you not reasonably have a virused and a non-virused orchid sitting side by side without transmitting the disease? Maybe as long as they didn't touch?

"Both CyMV and ORSV are only transmitted by humans through handling and division of orchid plants. There is no known transmission of these viruses by insects or through seed. Once an individual plant is infected, it is impossible to cure it. Control of virus diseases in orchid collections is possible if you have good management practices that do not permit spread of virus from any infected plants to healthy ones. Therefore, when propagating plants, all propagation implements such as knives, razor blades, benches and any other tools, should be sterilised. Cutting implements should be dipped in alcohol or methylated spirits and flamed, and benches should be washed down thoroughly with soap and hot water. "
