Risk factors
By Mayo Clinic staffPlantar warts are more likely to appear on the feet of people with:
- Damaged or cut skin
- Weakened immune systems
For reasons doctors don't understand, some people are more susceptible to the wart-causing virus, just as some people are more likely to catch a cold. Children and teenagers tend to be especially vulnerable to warts.
