A foot wart grows on the inner side of the foot, in about a diameter of 1cms. Foot warts mostly occur in children and adults, with a single wart that can manifest into several small warts, also referred to as a Mosaic Wart. It can easily be transmitted from one person to another by way of direct contact in the affected area, in public places like swimming pools and changing rooms. Also popularly known as Verrucaes, foot warts are caused owing to the Human Papilloma Virus (HPV) and appear similar to corns. The surface of foot warts is enveloped by black dots, small blood vessels which feed the foot warts.
