Warts are transmissiblre, innoculation being favoured by mild trauma.
They are commoner in children and young adults, and are usually self-limiting and benign. The hands, feet, face, around the knees, peri-anal and genital skin are the commonest sites. Because most warts resolve spontaneously, caution is needed in assessing therapy, and methods such as scalpel surgery and radiotherapy should be abandoned. Cryotherapy is uncomfortable but often more rapidly successful. Venereal warts are frequently associated with other sexually transmitted diseases, requiring appropriate investigations.
