The smart wart is Verrucae and is small skin growths caused by 80 or more human papillomaviruses. Warts can develop at any age but are most common in children and least common in older people. Warts can come as single growths or in hundreds. Repeated contact is necessary for the virus to spread and can spread from one area of the body to other areas rather than from one person to another, Most warts are harmless, although they may be quite bother some.
Warts are firm growths with a rough surface. They can be round or irregularly shaped and grey, yellow or brown in color. They are painless, except for plantur warts which can be very painful when pressure is placed on them.
The common warts disappear on their own within a year or two and rarely leave a scar when they heal spontaneously and do not need treatment unless painful or because of psychologic distress. In general they can be removed with chemicals, cut off, frozen of, or burned off with laser or electrical currents. Warts may recur after removal. Genital warts are more likely to persist and are more contagious and doctors have to treat them.
