Glossary On Causes of Warts

Human Papilloma Virus (HPV) is the primary culprit in the development of warts. There are more than hundred types of the Human Papilloma Virus (HPV) and most of them cause warts to develop on the skin. Some of the types of HPV cause genital warts and these have been implicated in the causation of cervical cancer in women.

The Human Papilloma Virus spreads though direct contact and that is the reason why warts spread from person to person as well as from one body part to another in the same individual. The virus finds way into the body through skin that is moist, cracked or is peeling. A site of recent injury is another common entry-point for the virus. Once the virus enters the body, the incubation period begins (during which the virus remains dormant) and this varies from one to eight months. After this period, the outbreak of the wart is seen.

Virus that has been shed recently remains alive in a warm, moist environment such as cellars, locker rooms, etc. There are numerous ways in which the virus can spread and these include:

  • From one part of the body to another (in the same individual)
  • Direct contact with someone else's wart
  • Contact with towel or any other object used by someone who has a wart
  • Genital contact as in vaginal/anal/oral sex (for genital warts)

Genital warts are much more contagious as compared to other varieties of warts.
