Warts in Children: Common, Harmless, and Treatable

Warts are common, harmless viral growths in kids caused by HPV. Most resolve on their own over time. A provider can discuss treatment if they cause pain or keep spreading.

Types of warts children get

Several types of warts appear in children 1. Common warts (verruca vulgaris) are rough, raised, dome-shaped growths usually found on the hands, fingers, and around the nails — they often have tiny dark dots inside, which are clotted blood vessels (capillaries), and have a rough, cauliflower-like surface texture. Plantar warts (verruca plantaris) grow on the soles of the feet and are pressed flat by body weight; they can be tender and sometimes feel like walking on a small pebble. Unlike common warts, plantar warts may grow inward, making them harder to treat.

Flat warts (verruca plana) are smoother and smaller than common warts, often appearing in multiples on the face, forehead, or legs — they are common in school-age children and teenagers. Filiform warts are thread-like or finger-shaped projections that sometimes appear around the mouth, nose, or eyelids.

The most common HPV strains causing warts in children are HPV 2, 27, 57, and 63 1. A provider can confirm which type of wart is present when there is uncertainty, which matters because treatment choices differ by location and type.

How warts spread

The HPV strains that cause common warts spread through direct contact with the virus, which can survive on surfaces for a short time 2. Walking barefoot in locker rooms, pool decks, and public showers is a common route for plantar warts 2. A child can also spread warts to other parts of their own body by picking or scratching.

Small cuts or breaks in the skin make it easier for the virus to take hold. Warts do not spread through casual contact as readily as some other infections, but sharing towels, socks, or shoes does carry some risk.

Do warts need treatment?

Many warts in healthy children disappear on their own as the immune system builds a response to the virus 12. Research shows approximately 93% of warts in children clear spontaneously by age 16, independent of treatment 1. Watchful waiting is a reasonable first approach for painless, non-spreading warts in a healthy child.

Treatment becomes worth considering when 2: - A wart is painful (especially plantar warts that press on the sole with every step) - It is spreading rapidly to new areas of the body - It is in a location that causes significant embarrassment or social difficulty - It is interfering with daily activity — a wart on a fingertip, for example, can be bothersome

Over-the-counter salicylic acid preparations are commonly used at home for appropriate warts; a provider can offer additional options such as cryotherapy (freezing), cantharidin, or immunotherapy. The AAD notes that cryotherapy is used primarily for older children and adults due to the pain involved 2. Even with treatment, warts may recur, since treatment removes the wart tissue but does not eliminate the underlying HPV from the surrounding skin.

Using over-the-counter wart treatments

Salicylic acid, available as a liquid, gel, or medicated pad in several concentrations, is a widely used first-line approach for common and plantar warts 2. It works by softening and gradually dissolving the layers of the wart over time through chemical exfoliation. For best results: soak the wart in warm water for five minutes to soften it, gently file the wart surface with a disposable emery board (do not reuse on other skin or share with others), and then apply the salicylic acid as directed on the packaging. Consistency matters — applications typically need to continue for several weeks, and stopping early is a common reason for incomplete clearance.

Important precautions: salicylic acid preparations are intended for use only on warts, not on facial skin, genitals, or near the eyes, and should not be used on irritated or broken skin 2. Read the product labeling carefully before use, and consult a provider if there is any uncertainty about whether the growth is a wart. For warts that do not respond after a patient, consistent home trial over several weeks, a provider can evaluate whether an in-office approach would be helpful.

Preventing wart spread at home and school

Keeping warts covered with a bandage can reduce the chance of spreading the virus to others or to other parts of the child's own body 2. Encouraging children not to pick or scratch warts, to wear flip-flops in communal showers and pool areas, and not to share towels or socks lowers the risk of spread.

Children with warts generally do not need to be kept home from school or excluded from activities 2. According to HealthyChildren.org, warts are not a standard reason for exclusion under school health guidelines.

Common questions

Can warts spread from my child to me or to siblings?

The HPV strains that cause common warts can spread through direct contact, though many adults have immune resistance from prior exposure. Avoiding sharing towels and not touching warts directly are sensible precautions.

Is a plantar wart the same as a corn or callus?

They can look similar, but plantar warts often have tiny dark dots inside (clotted blood vessels) and a distinctive grainy texture. A provider can distinguish them if there is uncertainty, which matters because treatment approaches differ.

How long does it take for a wart to go away on its own?

Most warts in children clear without treatment, and about 93% resolve by age 16. Individual warts may disappear within months, or some may take a year or two. Treatment can shorten the timeline but does not guarantee the wart will not recur.

My child has warts on their face — is that different?

Facial warts are usually flat warts and are common in children. Over-the-counter salicylic acid treatments are generally not suitable for facial warts. A provider visit is a good step for warts on the face, as they can recommend safer options.

When to get care right away

  • —A wart-like growth that changes color rapidly, bleeds without injury, or has irregular edges (should be evaluated promptly to rule out other causes)
  • —A plantar wart causing significant pain with walking
  • —Warts spreading rapidly to many new areas in a short period
  • —Any growth around the eye or on an eyelid — do not use home treatments here
