Warts and Plantar Warts - Cause
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 many months of slow growth beneath the skin
before you notice a wart.
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
