You’re helping your child get dressed or tying their shoes, and you notice a small, rough bump on a finger or the bottom of a foot. At first, it might not seem like a big deal. But then another bump shows up. Or your child starts complaining that walking hurts. If you’re wondering whether it’s a wart (and whether it’s going to spread), you’re not alone.
Warts are very common in children. They’re usually not dangerous, but they can be contagious, persistent, and frustrating, especially when they multiply or keep coming back. The good news is that there are practical steps you can take at home, and a dermatology provider can offer additional options when warts become painful, widespread, or hard to manage.
What Are Warts?
Warts are small growths on the skin caused by a virus. The virus enters through tiny breaks in the skin, such as a small cut, scrape, hangnail, or irritated area, and triggers excess skin cell growth at that spot. That’s why warts often appear on hands, fingers, around nails, or on the soles of the feet.
Children tend to get warts more often than adults because they have frequent exposure at school and in activities, and their immune systems are still learning to recognize and fight off certain viruses. Some kids clear warts quickly, while others take longer.
Why Warts Spread So Easily in Children
Warts spread easily because the virus can pass through direct contact and through shared surfaces. Kids are constantly moving, playing, and sharing spaces, so the opportunity for spread is higher than it is for most adults.
Common ways warts spread include:
- Skin-to-skin contact, especially during sports and play.
- Shared surfaces, such as locker room floors, pool decks, gym mats, and playground areas.
- Shared personal items, like towels, socks, shoes, nail clippers, and pumice stones.
- Auto-spreading occurs when a child picks, scratches, or bites nails and moves the virus to nearby skin.
- Moist environments, especially sweaty feet, can increase the chance of plantar warts spreading.
Because of this, warts can sometimes multiply even with good management, especially if the child touches the area without realizing it.
Common Types of Warts in Children (and Where They Show Up)
Warts can look different depending on where they appear and how the skin responds. A few types are especially common in kids:
Common warts usually show up on the hands and fingers. They often feel rough to the touch and may look like a firm, bumpy bump.
Plantar warts develop on the soles of the feet. Because they’re pressed inward by body weight, they can be painful, especially when standing or walking. Some kids describe plantar warts as feeling like a pebble in their shoe.
Flat warts are smaller and smoother than common warts. They can appear on the face, arms, or legs and may show up in groups.
Periungual warts form around the fingernails or toenails. These can be stubborn and may be more likely to spread if a child bites their nails or picks at the skin around the nail.
How to Tell If It’s a Wart (and When It Might Be Something Else)
Many parents can spot a wart by its appearance and texture, but it’s also easy to confuse warts with other common childhood skin issues.
Typical signs that suggest a wart include a rough or grainy texture, a firm bump, or a cluster of small bumps. Plantar warts may cause tenderness on the bottom of the foot and sometimes appear as tiny dark dots (small clotted blood vessels).
However, warts can look like other conditions, including:
- Calluses or corns, especially on the feet
- Molluscum contagiosum, another viral condition that can cause small bumps in children
- Skin tags or other benign bumps, depending on the location
Because treatment approaches differ, don’t treat aggressively if you’re unsure about the bump, especially on the face, around nails, or in sensitive areas.
When Parents Should See a Dermatology Provider
If you’re unsure whether your child’s bump is a wart or if you know it is and it’s becoming a bigger issue, professional evaluation can help.
Consider scheduling a visit if:
- Your child has painful warts or is limping (common with plantar warts)
- Warts are spreading quickly, or multiple new warts appear.
- Warts are around the nails or on the face.
- The area is bleeding, cracking, or showing signs of infection.
- Warts aren’t improving after several weeks of consistent home care.
- Your child feels embarrassed, stressed, or is being teased.
Even when warts aren’t medically serious, they can still affect a child’s comfort, confidence, and daily activities, especially when they’re visible or painful.
At-Home Wart Care That Can Help (and What to Avoid)
At-home care can be effective for some warts, especially when they are small and caught early. The key is consistency rather than strength. Many treatments fail because families stop too soon or keep switching approaches.
Helpful at-home habits include keeping the wart covered when possible, encouraging handwashing, and reminding children not to pick at the area. If the wart is on the foot, keeping feet clean and dry may also help limit the spread.
Over-the-counter treatments can also be useful in some cases. Products containing salicylic acid are commonly used and may help when applied correctly and consistently over time. It’s typically important to protect the surrounding skin and follow instructions carefully.
What to avoid is just as important. Many “DIY” wart-removal hacks can cause irritation, burns, or an increased risk of infection, especially in children. In general, it’s best to avoid cutting a wart at home, using harsh acids or unproven remedies, combining multiple aggressive treatments at once, or treating bumps that haven’t been clearly identified.
If a wart is near the eyes, face, nails, or is painful, a dermatology provider can guide treatment more safely.
Treatments for Warts in Children
When a child’s warts are persistent, spreading, painful, or located in a difficult area, in-office care can help. Dermatology providers choose treatment options based on the wart type, size, location, the child’s age, and their comfort level.
Common professional options include:
- Cryotherapy (freezing): A controlled treatment that targets the wart.
- Prescription topical treatments: Stronger formulations than many over-the-counter options.
- In-office topical applications: Some practices use specific in-office treatments depending on the case.
- Gentle removal approaches: In select situations, removal may be appropriate, especially if the wart is stubborn or interfering with daily life.
It’s also normal for warts to require more than one visit. Warts can be persistent because they involve both the virus and the skin’s immune response. A dermatology provider can help set realistic expectations and choose the approach that best balances effectiveness with comfort.
How Long Do Warts Last? What Results to Expect
Some warts go away on their own as the immune system recognizes the virus and clears it. For other children, warts can persist for months or longer, especially if they spread or if the child keeps reinjuring the area by picking or rubbing.
Key takeaways: Treatment speeds improvement, reduces spread, and relieves discomfort, especially for plantar warts or warts around nails. However, warts can return even after treatment since the virus may persist in nearby skin or a child may be re-exposed through shared surfaces. Prevention habits and follow-up help lower the risk of recurrence.
Preventing Warts From Spreading at Home and School
Key takeaway: Practicing a few habits can lower the spread of warts at home and school, protecting your child and others.
- Cover warts with a bandage when possible.
- Avoid picking warts and discourage nail biting.
- Don’t share towels, socks, shoes, or nail tools.
- Wear shower sandals in locker rooms and pool areas.
- Keep feet clean and dry (especially if your child has plantar warts)
These strategies can be especially helpful when one child in the household has warts and siblings share bathrooms, towels, or sports equipment.
