There are at least 70 different types of HPV, and they can infect skin on different parts of the body, so a wart's appearance often depends on its location, and the specific type of HPV that causes it. Warts are spread by direct contact and self innoculation. They occur in about 10 percent of children and are not usually serious, but can be annoying and uncomfortable.
Warts come and go, sometimes disappearing by themselves.
However, they are generally quite stubborn and can last for years. Copyright 2000 KinderStart. Inc. All rights reserved.
