Have cold sores? Keep them to yourselfBy Mayo Clinic staff
If you have cold sores, do your part to avoid spreading them to others: 1. Avoid skin-to-skin contact. This includes kissing. 2. Don't share utensils, towels, lip balm or other personal items. 3. Wash your hands before touching your eyes or genital area. 4. Wash your hands before touching another person.
