I have see the mosaic virus in my zuchini and my melon. I dob't know if its a dangerous strain and if i can sow again the seeds. The plant of zucchini was totally attack by the slug and has grow again with the mosaic.
there are more than one virus so each may be somewhat different in how they may be spread. yes, aphids can spread some of them, also via the seeds of some plants. some weeds may also host the virus and then be a source of infection.
my problem is that i grow so many different plants that i may not notice it right away, but there are few aphids around here so it doesn't often have a chance to spread.
pulling infected plants and disposing of them completely seems to be the best way to limit the damage and to keep an eye on surrounding plants.
i don't know anything about how easily it may be transmitted from the soil or dead plant materials that have been composted or just left in the weed pile. i worm compost but i don't use anything from under the weed piles so that probably prevents me from causing more issues...
