Common Warts: Causes, Symptoms, and Effective Treatment Options

Common warts, or verruca vulgaris, are one of the most common types of warts. They appear as small, grainy skin growths on the fingers, hands, knees, or elbows. These warts are rough to the touch and often feature tiny black dots on their surface. These dots are actually clotted blood vessels that supply the wart with nutrients.

Warts are contagious and can be spread through direct skin-to-skin contact or by touching surfaces that have been in contact with a wart. This is why they are more common in children (commonly known as kids’ warts) and individuals with weakened immune systems.

Although these warts often go away on their own over time, many people choose to remove them. This decision is often based on cosmetic concerns or discomfort, especially if the wart is irritated by daily activities like writing, gripping, or handshaking.

Causes of Common Warts

Human Papillomavirus (HPV) Infection

Certain strains of the Human Papillomavirus (HPV) cause common warts. This virus enters the body through tiny cuts, scrapes, or breaks in the skin. Once inside, it causes the skin cells to grow rapidly on the outer layer, forming a wart. Not all strains of HPV cause warts, and the ones responsible for common warts are usually different from those that affect the genital area.

How the Virus Spreads

HPV is highly contagious and can spread through direct or indirect contact. You can get the virus by touching a wart on someone else’s body or by using objects that carry the virus, such as towels, nail clippers, or razors. It also spreads in moist environments like communal showers, locker rooms, or swimming pool areas. The virus thrives in warm, damp places, making it easier to catch in such conditions.

Risk Factors

Certain conditions increase your risk of developing common warts:

• Cuts or damaged skin: Small breaks in the skin allow the virus to enter more easily. This is why warts are often found on fingers with hangnails or cracked skin.
• Weakened immune system: People with a compromised immune system are more likely to develop warts and may have trouble getting rid of them.
• Sharing personal items: Using items like nail files, socks, or shoes that someone with warts has used can lead to the spread of the virus.
• Frequent contact: Children and teens tend to get common warts more often because of close contact in schools and play areas, and their immune systems are still developing.

Symptoms of Common Warts

Physical Characteristics

• Common warts appear as small, raised skin growths with a rough, grainy texture.
• They are usually flesh-colored, white, or gray.
• Tiny black dots often found on the surface are clotted blood vessels, not dirt.

Common Areas Affected

Common warts are mostly developed on fingers, hands, and around the nails. They may also appear on knees, elbows, or other high-contact areas. Children and teens are usually more affected due to higher exposure and weaker immunity.

Duration and Progression

• Warts can take 2 to 6 months to appear after exposure to the virus.
• They may stay the same size, gradually grow, or spread to nearby skin.
• Many disappear on their own over months or years, depending on the immune response.

How Are Common Warts Diagnosed?

Doctors typically diagnose common warts by examining the skin for features like rough texture, black dots, and the wart’s location. Most cases don’t require further testing, though a doctor may scrape the surface to check for clotted blood vessels. If the diagnosis is uncertain, a skin biopsy may be done to rule out other conditions.

When to Seek Medical Evaluation?

You should see a doctor if a wart changes in appearance, grows rapidly, or becomes painful. Medical advice is also recommended when over-the-counter treatments fail after several weeks, or if you have multiple warts that keep returning.

People with weakened immune systems should always seek professional care for wart treatment. Most importantly, if you’re unsure whether the growth is a wart, it’s best to consult a healthcare provider.

At-Home Treatment Options for Common Warts

Explore effective treatment options for common warts to relieve discomfort and restore healthy skin.

1. Salicylic Acid Treatments

• Available in liquids, gels, and pads.
• Works by gradually peeling away layers of the wart.
• Most effective when used daily and after soaking the wart in warm water.

2. Duct Tape Method

• Involves covering the wart with duct tape for several days.
• The tape is removed, and the area is filed before reapplying.
• It may take several weeks to show results, and while it is easy and inexpensive, its effectiveness is not fully confirmed.

3. Natural Options (e.g., Tea Tree Oil)

• Tea tree oil has antiviral and antibacterial properties.
• Applied directly to the wart daily.
• Evidence is mostly anecdotal, and results vary from person to person.

4. Creams and Wart Removal Kits

• Often contain salicylic acid or similar ingredients.
• Designed for easy application at home.
• Instructions must be followed carefully for the best results.

5. Freezing Sprays

• Mimic cryotherapy using a lower-temperature freezer.
• Applied directly to the wart, causing it to blister and fall off.
• May require multiple applications for larger or stubborn warts.

Medical & Surgical Treatments for Common Warts

1. Cryotherapy (Professional Freezing)

• Performed by a healthcare provider using liquid nitrogen.
• Freezes the wart at a much lower temperature than OTC products.
• It often requires repeat sessions but is effective for most people.

2. Electrosurgery or Curettage

• Electrosurgery burns the wart tissue using an electric current.
• Curettage involves scraping off the wart with a surgical tool.
• These are usually used for larger or stubborn warts.

3. Laser Treatment

• Targets blood vessels in the wart to destroy tissue.
• Often used when other methods fail.
• May be more expensive and require healing time.

4. Immunotherapy Options

• Stimulate the immune system to fight off the wart-causing virus.
• Can involve topical treatments or injections.
• Often used for recurring or resistant warts.

Prevention Tips for Common Warts

Stay safe from common warts and other skin issues by acting on these tips:

1- Avoid direct contact with warts: Refrain from touching your own or others’ warts, as this can spread the virus to other parts of the body or to others.

2- Keep skin healthy and moisturized: Healthy, intact skin acts as a barrier against viruses. Moisturized skin is less likely to crack, reducing entry points for HPV.

3- Avoid sharing personal items: Do not share towels, razors, socks, or nail tools, as the virus can linger on these surfaces and spread through indirect contact.

4- Proper wound care to prevent infection: Cover cuts or scrapes with clean bandages and keep them clean. This helps block the virus from entering through broken skin.

Conclusion

In conclusion, common warts (verruca vulgaris) are generally harmless but can be uncomfortable or bothersome. With several treatment options available, ranging from home remedies to medical procedures, early care helps manage symptoms and prevent the spread. If warts persist, consulting a healthcare professional ensures the right treatment approach for long-term relief and skin health.
