Warts are caused by a virus known as the papova virus. The numerous strains of papova virus that cause the common wart are transferred by physical contact and enter the skin at the point of contact. Contrary to popular belief, the wart virus is not systemic and does not 'circulate through your system'. Warts are only contracted by direct contact on the skin. The papova virus has a long incubation period ranging from 1 to 20 months, meaning that it may take quite some time before a person will even notice any presence of the wart. One theory regarding the etiology of warts suggests that the virus is able to enter the skin at areas where the skin has sustained recurrent damage. The skin on the hands and feet can be damaged in a number of different ways. Examples of injuries include fissures or cracks in the skin, fissures in the cuticle, chronic nail biting and maceration caused by excessive perspiration. Warts seem to thrive in skin that is thick and moist. Therefore, we tend to find warts on the palm of the hand and the sole of the foot.
