When you have a verruca or a plantar wart on your foot refrain from picking and trying to remove it using your fingers. It also spreads very easily to other skin and areas. In the images shown, the original warts were on the feet and have spread to the fingers and around the fingernails from a manicure. The virus can also spread from using the same tools such as a cuticle cutter and then using them your wart to trim off the dead skin like so do to remove a corn. Picking and playing with the warts and verrucae out of habit will spread the virus to other fingers and toes and skin areas.
For example, if you have a wart on your finger and you bite your finger nails, you can spread the warts to your lips. Similarly, if you sleep on your side with your hand on your cheek you can spread it to your face.
