Medical Reference
A.

A wart develops when a human papillomavirus infects the outermost layer of skin and causes the skin cells to grow rapidly. The virus can then spread from an existing wart to other areas of the body, causing more warts. Various types of this virus thrive in warm, damp environments such as showers, locker room floors, and swimming pool areas.

You are most likely to develop a wart where you have broken skin, such as a cut, hangnail, closely bitten nail, or scrape. Plantar warts are common to swimmers whose feet are not only damp and softened but are also scratched and broken by rough pool surfaces. Common warts are often seen among those who handle meat, chicken, and fish.

How are warts spread?

Warts are easily spread by direct contact with a human papillomavirus. You can reinfect yourself by touching the wart and then another part of your body. You can infect others by sharing towels, razors, or other personal items. After exposure to a human papillomavirus, it can take 2 to 9 months of slow growth beneath the skin before you notice a wart.1

It is unlikely that you will develop a wart every time you are exposed to a human papillomavirus. Some people are more likely to develop warts than others.

Genital warts are very contagious. For more information, see the topic Genital Warts.
