1. What Are Warts and Why Are They Common in Children?
Warts are noncancerous skin growths caused by a viral infection, specifically by different types of the human papillomavirus (HPV). They can appear anywhere on the body, but are most commonly found on the hands and feet. Children are particularly susceptible to warts due to their developing immune systems and frequent exposure to environments where HPV can thrive, such as schools, playgrounds, and swimming pools. According to the American Academy of Dermatology, warts are most common in children and young adults.
1.1 What Exactly Are Warts?
Warts are benign skin tumors that occur when HPV infects the top layer of skin. The virus causes the skin cells to grow rapidly, creating a raised, often rough bump on the skin’s surface. Warts are typically skin-colored, but they can also be darker or lighter. They may also have small black dots, which are actually clotted blood vessels.
1.2 Why Are Children More Prone to Warts?
Children are more susceptible to warts for several reasons:
- Developing Immune System: Children’s immune systems are still developing, making them less effective at fighting off viral infections like HPV.
- Hygiene Habits: Children often have less stringent hygiene habits, increasing their exposure to HPV in various environments.
- Minor Injuries: Kids frequently experience minor cuts and abrasions, which provide entry points for the virus to infect the skin.
- Public Exposure: Schools, playgrounds, and swimming pools are common breeding grounds for HPV, where children often come into close contact with others.
2. What Causes Warts in Children?
Warts are caused by the human papillomavirus (HPV). There are over 100 different types of HPV, and only a few of these cause common skin warts. Understanding how HPV spreads and infects the skin can help prevent warts in children.
2.1 The Role of HPV in Wart Development
HPV infects the top layer of skin, usually entering through a cut or break. The virus then triggers rapid growth of cells on the outer layer of skin, leading to the formation of a wart.
2.2 How HPV Spreads
HPV spreads through direct contact with a wart or a surface contaminated with the virus. Common ways children contract HPV include:
- Direct Skin Contact: Touching a wart on someone else’s body.
- Contaminated Surfaces: Walking barefoot in public showers, locker rooms, or around swimming pools.
- Sharing Personal Items: Sharing towels, razors, or other personal items with someone who has warts.
- Autoinoculation: Spreading the virus to other parts of their own body by touching or scratching a wart and then touching another area.
2.3 Factors Increasing the Risk of Wart Development
Several factors can increase a child’s risk of developing warts:
- Weakened Immune System: Children with weakened immune systems are more susceptible to HPV infection.
- Skin Damage: Any cuts, scrapes, or breaks in the skin provide an entry point for HPV.
- Nail Biting: Nail biting can create small tears around the nails, increasing the risk of HPV infection.
- Exposure in Public Places: Frequenting public places like swimming pools and gyms increases the likelihood of exposure.
3. What Are the Different Types of Warts Found in Children?
Warts come in various forms, each with distinct characteristics and locations on the body. Recognizing these different types is crucial for proper identification and treatment.
3.1 Common Warts
Common warts (Verruca vulgaris) are typically found on the hands, fingers, and knees. They have a rough, raised surface and are usually round or oval in shape. Common warts may also feature tiny black dots, which are clotted blood vessels.

3.2 Plantar Warts
Plantar warts appear on the soles of the feet. They are often flat and grow inward due to pressure from walking. Plantar warts can be painful, feeling like a pebble in the shoe. They may also have black dots and often occur in clusters.
3.3 Flat Warts
Flat warts are smaller and smoother than other types of warts. They usually grow in large numbers, often 20 to 100 at a time. Flat warts are most common on the face, arms, and knees.
3.4 Filiform Warts
Filiform warts are long, thin warts that often grow around the mouth, nose, or eyes. They are flesh-colored and tend to grow quickly. While usually painless, their location can make them bothersome.
3.5 Periungual Warts
Periungual warts appear around the fingernails and toenails. They can distort nail growth and can be painful. These warts are often difficult to treat due to their location.
4. How Are Warts Diagnosed in Children?
Diagnosing warts in children usually involves a visual examination by a healthcare provider. In some cases, further testing may be necessary to rule out other skin conditions.
4.1 Visual Examination
A doctor typically diagnoses warts by looking at them. The appearance, location, and texture of the wart are usually enough to determine the type of wart and the appropriate treatment.
4.2 Dermoscopy
A dermoscopy is a non-invasive diagnostic procedure that uses a magnifying lens and a light source to examine the skin more closely. This can help differentiate warts from other skin conditions and identify characteristic features such as tiny black dots.
4.3 Skin Biopsy
In rare cases, a skin biopsy may be necessary to confirm the diagnosis. This involves removing a small sample of the wart tissue and examining it under a microscope. A biopsy is usually only performed if the diagnosis is uncertain or if the wart has unusual characteristics.
5. What Are the Available Treatment Options for Warts in Children?
There are various treatment options available for warts in children, ranging from over-the-counter remedies to medical procedures. The best treatment approach depends on the type, location, and number of warts, as well as the child’s age and overall health.
5.1 Over-the-Counter Treatments
Several over-the-counter treatments are available for warts, typically containing salicylic acid. These treatments work by gradually dissolving the wart tissue.
5.1.1 Salicylic Acid
Salicylic acid is a common ingredient in over-the-counter wart treatments. It is available in various forms, including liquids, gels, pads, and plasters. The treatment involves applying the salicylic acid to the wart daily after soaking it in warm water.
5.1.2 Freezing Kits
Over-the-counter freezing kits are also available, using dimethyl ether and propane (DMEP) to freeze the wart. These kits are less effective than liquid nitrogen used by doctors but can be a convenient option for some.
5.2 Prescription Medications
If over-the-counter treatments are ineffective, a doctor may prescribe stronger medications.
5.2.1 Topical Medications
Prescription-strength topical medications, such as imiquimod, can stimulate the immune system to fight the virus. Tretinoin cream might also be prescribed to promote skin cell turnover.
5.2.2 Cantharidin
Cantharidin is a topical medication applied by a doctor. It causes a blister to form under the wart, eventually cutting off its blood supply. The blistered wart can then be removed in a follow-up visit.
5.3 Medical Procedures
Several medical procedures can be used to remove warts, particularly for persistent or painful warts.
5.3.1 Cryotherapy
Cryotherapy involves freezing the wart with liquid nitrogen. This procedure is performed by a doctor and may require multiple sessions. Liquid nitrogen freezes the wart tissue, causing it to die and eventually fall off.
5.3.2 Electrocautery and Curettage
Electrocautery involves burning off the wart with an electric current. Curettage involves scraping off the wart with a sharp instrument. These procedures are often used together and are performed by a doctor.
5.3.3 Laser Treatment
Laser treatment uses a concentrated beam of light to destroy the wart tissue. This method is often used for warts that have not responded to other treatments.
5.3.4 Surgical Excision
Surgical excision involves cutting out the wart. This is usually reserved for warts that are large, painful, or have not responded to other treatments.
5.4 Alternative Therapies
Some alternative therapies have been suggested for treating warts, although scientific evidence supporting their effectiveness is limited.
5.4.1 Duct Tape Occlusion
Duct tape occlusion involves covering the wart with duct tape for several days, then removing the tape and debriding the wart. This process is repeated over several weeks.
5.4.2 Tea Tree Oil
Tea tree oil has antiviral and antiseptic properties and may help treat warts when applied topically.
5.4.3 Garlic
Applying crushed garlic or garlic extract to the wart may help due to garlic’s antiviral properties.
