Can you transfer a verruca on the foot to the mouth or genitals?

Warts: The virus also needs to have a point of entry into the skin: cracks in dry skin, cuts or scrapes, wet, softened, fragile skin from prolonged water exposure (macerated skin). Each person's immune system responds differently to hpv, so not everyone who comes in contact with the virus develops warts. Even people in the same family react to the virus differently.
