Close to 100 different types of HPV have been identified and they have affinity for different types of body tissue. Most types of HPV have an affinity for the skin and produce common warts (verruca vulgaris), flat warts(verruca plana) and plantar or foot warts (verruca plantaris). Several other types of HPV have an affinity for mucous membranes and some of these cause ano-genital warts (condyloma acuminata).
