Warts

Warts Overview

Warts are small harmless tumors of the skin caused by a virus called the human papillomavirus. The appearance of warts can differ based on the type of wart and where it is located on the body. Most warts are well defined, with skin thickening.

  • Warts are common in children. Most cases occur between ages 12-16 years.
  • Up to 30% of warts disappear by themselves within 6 months. Most will disappear without any treatment within 3 years.

Furthermore, if a person touches the rash and then another part of his or her body, it can cause spread to that area (known as autoinoculation).
