If you have warts, you can spread the virus to other places on your body. Here's how to stop the spread: 1. Don't brush, clip, comb or shave areas with warts. 2. Don't use the same file or nail clipper on warts as you use on healthy nails. 3. Don't pick at warts. If you can't keep your hands off, cover your warts with an adhesive bandage. 4. Wash your hands carefully after touching your warts.
