There are several different types of mosaic viruses, and without knowing which one affected your veggies, it’s impossible to tell what type of plants the virus might infect in the future. Generally, they have a wide range of host plants, so it’s likely that the virus would persist in whatever you plant next. Therefore, we would recommend avoiding planting anything in that spot for the time being. Clear out the patch of all plant matter (including roots) and burn it, if possible (do NOT put it in your compost pile). Let the plot sit empty for at least a year (two is better), and then try planting again. You may want to look into buying mosaic-virus–resistant vegetable varieties for an extra layer of protection.
