Warts and verrucas are both growths that appear on the skin as a result of a virus. Warts generally appear on the hands and are easily recognisable due to the rough appearance on the surface of the skin. Verrucas mostly appear on the foot. They can be painful and are visible because of the white ring that appears around them. If left untreated, warts and verrucas can spread, on the body as well as another person.
