A wart is a hardened, bumpy, or rough piece of skin that grows faster than normal. Warts are caused by infection with the human papilloma virus (HPV). Most warts are harmless, but the virus that causes warts is contagious and can be spread by direct contact with others. Warts may develop anywhere on the body, including the bottom of the feet, palm of the hands, fingers, and genitals. Warts are typically brown or flesh-colored, although genital warts may also appear pink or red.
