About 10 strains of HPV cause skin warts, which can spread by direct contact through breaks in the skin.
To get rid of a wart, Harvard suggests trying a salicylic acid treatment:
- Soak the wart for 10 to 15 minutes.
- File away the dead skin with an emery board or pumice stone.
- Apply salicylic acid to the wart area.
- Repeat once or twice a day for 12 weeks.
