Warts

Individuals who are in close physical contact with someone who has warts have a higher chance of developing the condition. Other factors that increase the risk include:

Weakened immune system

• People with compromised immune systems struggle to fight off infections, making them more vulnerable to viruses like HPV. This category includes individuals who have undergone organ transplants or have illnesses such as cancer or HIV.

Age

• Children and adolescents are more prone to contracting warts, with the highest incidence occurring between ages 12 and 16.

Race

• Warts are more commonly observed among White populations compared to Black or Asian groups. Focal epithelial hyperplasia tends to be more frequent among Inuit and American Indian populations.

Medical conditions

• Skin disorders like eczema and dermatitis can increase the risk of developing warts.

Occupation

• People who frequently handle raw meat are at greater risk of HPV infection. Similarly, habits like nail-biting and picking at hangnails raise the likelihood of developing warts.

Unprotected sexual activity

• Engaging in unprotected oral, anal, or vaginal sex with an infected partner significantly raises the risk of contracting genital warts.

Smoking

• Research indicates that smoking may be associated with an elevated risk of developing genital warts.

Diagnosis typically involves the following methods:

Clinical examination

• Since each wart type has distinct features and preferred locations, most cases are identified through a visual inspection by an experienced healthcare provider.

Dermoscopy

• This technique uses a specialized magnifying device with a strong light source to examine skin abnormalities in detail.

Immunohistochemical (IHC) detection

• This method uses antibodies to identify specific proteins or antigens in a skin tissue sample, confirming the presence of the virus.

Southern blot hybridization

• A highly sensitive test used to detect and identify specific types of HPV present in tissue samples.

Polymerase chain reaction (PCR)

• PCR amplifies the genetic material of the virus, offering a precise confirmation of its presence within lesions.

Biopsy

• If there is suspicion of cancerous changes, a skin tissue sample is collected for detailed examination.

Although it is difficult to completely avoid HPV infection due to its highly contagious nature, certain practices can help lower the risk:

Vaccination

HPV vaccines offer protection against anal and genital warts and several cancer-causing strains of the virus. Vaccination is recommended for individuals aged 9 to 45. Receiving the vaccine early ensures maximum protection.

Vaccination schedule:

• A 2-dose series is advised for those who receive their first shot before turning 15, with the second dose administered 6–12 months after the first.
• A 3-dose series is recommended for those starting the vaccine after their 15th birthday or for individuals with specific immunocompromising conditions.

Foot care

Maintaining proper foot hygiene can prevent plantar warts.

Measures include:

• Washing feet daily with soap and water
• Thoroughly drying feet, especially between toes
• Wearing clean, moisture-wicking socks and changing them regularly
• Opting for open-toed footwear to allow ventilation
• Rotating shoes to let them air out
• Wearing sandals in communal showers and locker rooms
• Avoiding the use of shared foot care tools like pumice stones or nail files

Wound care

Preventing HPV infection through open wounds involves:

• Washing hands frequently with soap and water
• Using alcohol-based hand sanitizers when handwashing is not possible
• Keeping wounds clean and covered until they heal
• Avoiding hot tubs, swimming pools, lakes, rivers, and oceans until wounds have fully healed

Hand hygiene

Regular handwashing, especially after sneezing, coughing, preparing food, or before eating, can reduce the risk of transmission.

Skin moisturization

Dry, cracked skin is more susceptible to HPV. Applying moisturizer within five minutes after bathing or when the skin feels dry helps protect the skin barrier.

Maintaining the skin barrier

Managing skin conditions like eczema and avoiding exposure to irritants or allergens helps preserve the skin's protective barrier.

Avoid nail-biting and cuticle chewing

These habits cause small skin injuries that can facilitate HPV entry. Breaking these habits can significantly lower the risk of infection.

Managing excessive sweating

Damp skin encourages viral growth. Treating conditions that cause excessive sweating helps in minimizing wart development.

Regular skin check-ups

People with conditions such as diabetes or obesity should undergo routine skin examinations. Early identification and management of skin injuries can prevent infections. Diabetic individuals should also inspect their feet daily for any signs of damage.

Specialists to Visit

While many wart cases can be managed with over-the-counter remedies and home treatments, medical advice should be sought in the following scenarios:

• Doubt about whether the growth is a wart
• Warts located on the face or genitals
• Presence of multiple warts
• Intense itching or burning sensations
• Painful lesions
• Low immune function
• Presence of diabetes

Healthcare providers to consult include:

• General Physician: Assesses symptoms and initiates treatment.
• Dermatologist: Specializes in diagnosing and treating skin conditions.
• Cosmetologist: Focuses on cosmetic management of the skin, nails, and hair and performs various in-office treatments.

There is currently no treatment that guarantees a permanent cure for warts, and they tend to recur frequently. Several therapeutic options are available:

1. Topical Therapies

These are applied directly to the warts in the form of creams, gels, or lotions. Common treatments include:

• Salicylic acid: Considered the first-line treatment for most common warts.
• Tretinoin: Primarily used for the management of flat warts.
• Dibutyl squaric acid (Squaric acid dibutyl ester or SADBE) and Diphenylcyclopropenone (DCP): These contact sensitizers help activate the immune system to provide symptomatic relief.
• Imiquimod: This gel stimulates the body’s immune response and is effective for treating genital and common warts.
• 5-Fluorouracil: An anti-cancer agent also used to address stubborn warts.
• Cidofovir: An antiviral medication effective for treating warts unresponsive to conventional therapy.

2. Intralesional Therapy

This method involves injecting medication directly into the wart. Examples include:

• Skin test antigen injections: Utilizing viral or fungal extracts to stimulate the immune system’s response against the wart.
• Bleomycin: A chemotherapy drug that suppresses the wart virus’s growth.
• Interferon-alfa: An immunomodulatory agent with antiviral and anticancer properties, often reserved for resistant cases.

3. Clinical Procedures

These minimally invasive techniques are performed in medical settings:

• Cantharidin application: A blistering agent derived from beetles that removes the infected skin layer.
• Trichloroacetic acid: Destroys superficial skin tissue containing the virus.
• Cryotherapy: Freezing warts with liquid nitrogen, usually repeated every 1–4 weeks for about three months.
• Curettage: Scraping away the wart with a surgical instrument.
• Excision: Surgically removing the wart.
• Photodynamic therapy: Using light combined with photosensitizing agents to destroy wart-infected tissue.
• Laser therapy: Directing focused laser beams at the wart, generally used for severe or large warts.

Though about two-thirds of warts resolve spontaneously over several years, some may result in scarring, especially following topical treatments.

Certain HPV strains linked to genital warts have been associated with an increased risk of cervical, vulvar, anal, and, rarely, penile cancers.

Occasionally, warts located on the vaginal walls may hinder vaginal elasticity during childbirth, necessitating a cesarean section.

Several alternative methods may offer benefits, but it's important to discuss these with a healthcare provider beforehand:

• Podophyllin Resin: Extracted from May apple roots, effective for treating genital and plantar warts by inhibiting viral replication. Podofilox is a less irritating variant available commercially.
• Duct Tape Therapy: Covering the wart with duct tape creates an environment that facilitates its removal.
• Hypnosis: Involves using guided imagery, such as visualizing freezing the wart, to encourage resolution. Success rates range from 27% to 55% in children.
• Hyperthermia: Involves soaking the affected area in hot water for 30–45 minutes, two to three times a week.

Some home-based approaches might aid in managing warts, but it’s crucial to consult a healthcare provider before starting any remedy:

• Garlic: Known for its antimicrobial properties. Method: Crush garlic, mix with water, and apply daily for 3–4 weeks.
• Orange peel: Method: Rub an orange peel directly on the wart daily until it diminishes.
• Pineapple: Contains bromelain, an enzyme that removes damaged tissue. Method: Apply pineapple juice on the wart.
• Honey: Renowned for its antiviral and antibacterial effects. Method: Apply honey on the wart and leave it for 15–20 minutes.
• Green Papaya: Provides enzymes that dissolve dead skin. Method: Collect sap from an unripe papaya, mix it with papaya pulp and water, and apply the paste twice daily for 15–20 minutes.
• Aloe Vera: Acts as a natural skin healer. Method: Apply Aloe vera gel on the wart and leave it on for 30–45 minutes.
• Apple Cider Vinegar: Helps peel away infected skin. Method: Apply diluted apple cider vinegar using a cotton ball directly onto the wart.

Although warts can be persistent and inconvenient, most resolve naturally. Several measures can aid in recovery and minimize their spread:

• Cover the warts: Prevents spreading the virus to other parts of the body and other individuals.
• Wash hands after touching warts: Essential to avoid virus transmission.
• Avoid shaving over warts: Shaving can create micro-cuts, facilitating virus spread. Avoid shaving affected areas when possible.

Preventing Wart Transmission

Since wart-causing viruses spread easily, adopting a proactive approach can limit transmission:

• Avoid direct contact with warts.
• Use waterproof bandages while swimming.
• Do not share personal items such as towels, shoes, or gloves.
• Wash hands frequently, especially after wart contact.
• Refrain from picking or scratching warts.
• Wear flip-flops or protective footwear in communal showers and locker rooms.
