Skin warts come in several varieties.
Common warts are rounded, raised, rough bumps that are most frequently found on the fingers and hands. Flat warts are very small, slightly rough and may come in groups, especially in areas where they have been spread by trauma, such as shaving. Like genital warts, warts on the skin are spread by direct contact. However, warts on skin are less contagious than warts on mucous membranes such as the vulva. The flat dead cells are less likely than the ones underneath to harbor infectious virus.
