What are warts?

Warts are small skin lesions caused by a virus. The viruses that cause warts can be transmitted from person to person. A wart may be rough or smooth, flat or raised, and is usually hard to the touch. Warts are typically a different color than the surrounding skin.

Different varieties of warts can appear on different parts of the body. For example, some wart varieties typically appear on the soles of the feet. Other varieties can affect the face or the hands. Warts that affect the genitals and surrounding areas may be sexually transmitted diseases.

Warts are caused by viruses; the human papilloma virus (HPV) is the most common cause of warts in children and adults. Once the virus enters the skin, there is a rapid growth of the top layer of the skin. Warts may grow on any part of the skin and typically most warts caused by HPV will resolve on their own within a few months or years.

Warts are growths in and under the skin that are caused by the Human Papillomavirus. They come in many varieties, with their appearance usually determined by where the wart is located. Warts don't typically result in long-term health problems.
