Sorry to hear the news. The mosaic virus can overwinter in the roots of perennial weeds, flowers, and some crops plants. It grows with the plant in the spring, appearing in the upper leaves. However, it can not live in extremely dry conditions. As for planting now, avoid plants varieties that are susceptible to the cucumber mosaic virus; grow resistant cultivars and use resistant seeds. Consider using row covers to prevent aphids from reaching plants in the first place (aphids bring on CMV). This page from the Tennessee cooperative extension service provides a list of vegetables and varieties and resistance: https://extension.tennessee.edu/publications/documents/SP277-K.pdf
You might get more information from your local cooperative extension service. Search for your state here and find the resources: /content/cooperative-extension-services
