Many of us have had a wart somewhere on our bodies at some time. Other than being a nuisance, most warts are harmless. More common in kids than in adults, warts are skin infections caused by viruses of the human papillomavirus family. They can affect any area of the body, but tend to invade warm, moist places, like small cuts or scratches on the fingers, hands, and feet. Warts are usually painless unless they're on the soles of the feet or another part of the body that gets bumped or touched all the time. 

Types of warts :

Common warts
Usually found on fingers, hands, knees, and elbows, a common wart is a small, hard bump that's dome-shaped and usually grayish-brown. It has a rough surface that may look like the head of a cauliflower, with black dots inside. 

Flat warts
These are about the size of a pinhead, are smoother than other kinds of warts, and have flat tops. Flat warts may be pink, light brown, or yellow. Most kids who get flat warts have them on their faces, but they can also grow on arms, knees, or hands and can appear in clusters.

Plantar warts
Found on the bottom of the foot, plantar warts can be very uncomfortable like walking on a small stone. Filiform warts. These have a finger-like shape, are usually flesh-colored, and often grow on or around the mouth, eyes, or nose. Sometimes warts are sexually transmitted and appear in the genital area, but most warts appear on the fingers, hands, and feet. 

Are Warts Contagious?
Simply touching a wart on someone doesn't guarantee that you'll get one, too. But the viruses that cause warts are passed from person to person by close physical contact or from a surface that a person with a wart touches, like a bathmat or a shower floor. 
A tiny cut or scratch can make any area of skin more vulnerable to warts. Also, picking at a wart can spread warts to other parts of the body. 
The length of time between when someone is exposed to the virus that causes warts and when a wart appears varies. Warts can grow very slowly and may take weeks or longer, in some cases, to develop. 

Preventing Warts
Although there's no way to prevent warts, it's always a good idea to encourage kids to wash their hands and skin regularly and well. If your child has a cut or scratch, use soap and water to clean the area because open wounds are more susceptible to warts and other infections. It's also wise to have kids wear waterproof sandals or flip-flops in public showers, locker rooms, and around public pools (this can help protect against plantar warts and other infections, like athlete's foot)
