Raven, yes, CMV can be spread to other plants and vines, but I agree with Calalily that yours does not look like CMV.
I'm not convinced that yours has a virus. It could be a deficiency of some sort.
Some tropical plants and vines do carry viruses, but most of the time it doesn't affect the vine or the plant adversely. For example, many variegated Abutilons have a virus, and it is the virus that gives the variegation. Most tropical plants and vines propagated in commercial greenhouses have been subjected to all sorts of viruses. There is no cure for a plant virus.
If you purchased this vine and are concerned about the appearance of the leaves, then I would send it back and ask for a new one.
When I wrote to Logee's to ask their opinion, I received a very nice response. I think this part was the most helpful:
"As for your plant what to do with it? I would enjoy it and not worry about your other plants in your collection for if they are older cultivars they most certainly have been exposed to viruses. If you want to take precautions make sure you disinfect your cutting utensils between varieties when pruning. It's always beneficial to have virus free plant material and much of the high volume annual and crop material in contemporary horticulture is clean, but if we're to grow the multitude of unusual and exotic plants found in the world, we'll at the present time have to live with the reality of viruses in our plants. Incidently, some plants when infected with viruses are killed. Example of this are the New Guinea Impatiens which when infected go into a decline and die. Other like the passionflower show the symptoms yet have been growing with the viruses for years. The bad new is that we don't get to experience the full vigor of the plants we grow."
