Short of living in a sterile bubble, there's no 100% foolproof way of avoiding viral infections, but there are ways of reducing the risks.
Avoid warm, crowded places as much as you can.
Wash your hands frequently, especially if in contact with other people who have a virus.
Keep yourself fit and eat a healthy diet - one that will keep your immune system robust.
Take Vitamin C and Zinc supplements if necessary to ward off colds.
These are just a few suggestions. Other blurters may have more ideas.
Hope this helps
