Warts are growths on your skin caused by an infection with human papilloma virus, or HPV. Types of warts include
- Common warts, which often appear on your fingers
- Plantar warts, which show up on the soles of your feet
- Genital warts which are a sexually transmitted disease
- Flat warts, which appear in places you shave frequently
Common warts are caused by an infection with the human papilloma virus (HPV). More than 100 types of HPV exist, but only a few cause warts on your hands. Other types of HPV are more likely to cause warts on your feet and other areas of your skin and mucous membranes. Most types of HPV cause relatively harmless conditions such as common warts, while others may cause serious disease such as cancer of the cervix.
You can get warts from skin-to-skin contact with people who have warts. If you have warts, you can spread the virus to other places on your own body. You can also get the wart virus indirectly by touching something that another person's wart touched, such as a towel or exercise equipment. The virus usually spreads through breaks in your skin, such as a hangnail or a scrape. Biting your nails also can cause warts to spread on your fingertips and around your nails.
Each person's immune system responds to the HPV virus differently, so not everyone who comes in contact with HPV develops warts.
