What it is
A common wart is a small, rough-feeling growth on the skin. It is caused by a human papillomavirus (HPV), a very large family of viruses. The types that cause hands-and-fingers warts are different from the types linked to genital warts. Warts often appear on fingers, around the nails, on the backs of the hands and on the knees or elbows.
Are warts contagious? Yes, they can be. The virus can pass through direct skin contact or through shared surfaces such as towels, gym equipment and damp floors. It tends to enter through tiny breaks in the skin, like a hangnail or a nibbled cuticle. Not everyone who is exposed gets a wart, and people's bodies respond differently.
Warts can look like other things. A wart vs. callus question is common: calluses are thickened skin from pressure or friction, while warts are a viral growth, and they can look alike. Only a licensed clinician can tell them apart after an exam. Any growth that is changing, bleeding, itching, irregular in shape or color, or not healing should be checked by a dermatologist for skin cancer. Please don't try to self-treat it.
How it’s traditionally been approached
Many common warts go away on their own over time, and some people choose to wait. How long warts last varies a great deal from person to person. They can fade in months, linger for years or come back after clearing. A provider can talk with you about what to expect for your situation.
Over-the-counter wart products, usually with salicylic acid, are one traditional home option. Some people also try covering a wart with tape. Results vary, and these products are not right for everyone. People with diabetes, poor circulation, neuropathy or a weakened immune system should ask a provider before treating warts at home, especially on the feet. Facial and genital warts should not be treated with over-the-counter wart products. Cutting, burning or digging out a growth at home is not advised.
In a clinic, providers have traditionally used approaches such as freezing, prescription topical medicines, minor in-office procedures or other methods. Which one is appropriate, if any, is a decision for a licensed clinician after an evaluation. No approach is guaranteed to cure warts or HPV or to prevent them from returning. If a prescription product comes up, ask your provider about its current FDA status.
How the right provider may help
The right provider may help by first looking at the spot and confirming what it is. A dermatologist, podiatrist or primary care clinician can tell a wart from a callus or from something that needs a closer look. That exam is the safest place to begin, and it may give you peace of mind.
A visit is usually a conversation and a quick look at the skin. The clinician may ask how long the spot has been there, whether it has changed, and what you have already tried. They may also ask about health conditions or medicines that affect healing. Many people find it relieving to be taken seriously and not judged.
Questions you might bring: What is this growth? Is it okay to wait and watch? What are my options, and what are their trade-offs? What should I avoid at home? How can I lower the chance of spreading it to others or to other fingers? What signs mean I should come back sooner? Your provider decides what fits you, and results can vary.
The whole-person view
Body, mind and stress are connected. A lot of people feel self-conscious about visible warts on their hands, and that worry can affect confidence, social comfort and even habits like picking at the skin. Stress and general health can also play a part in how the body copes day to day. Looking after sleep, nutrition and rest is part of whole-person care, and none of it replaces an exam.
If the stress or embarrassment feels heavy, support exists. Somatic Experiences offers body-based support for people who want to work with how stress is held in the body, and Therapists.plus lists talk therapists for people who want to talk things through. These are optional supports that sit alongside care from a licensed clinician, and neither one is a wart treatment.

- Warts.ai is educational only and is not medical advice. A licensed clinician (dermatologist, podiatrist, primary care or sexual-health provider) should examine any growth.
- A spot that is changing, bleeding, itching, irregular in shape or color, or not healing should be checked by a dermatologist for skin cancer. The ABCDEs of melanoma are only a general guide and are not a way to diagnose yourself.
- Warts can return after they clear, and no approach is guaranteed. Ask a provider before home treatment if you have diabetes, poor circulation, neuropathy or a weakened immune system.
- For emergencies call 911. If you are in a crisis, call or text 988.

Frequently asked questions
What causes warts?
Warts are caused by infection of the skin with a human papillomavirus (HPV). The virus usually gets in through small breaks in the skin. Why one person gets a wart and another doesn't isn't fully predictable, so it is not a hygiene or character issue.
Are warts contagious?
Yes, warts can spread through direct skin contact or through shared damp surfaces and items such as towels. They can also spread from one finger to another on the same person. Covering the wart, not picking at it and washing hands may help lower the chance of spreading, but nothing is guaranteed.
What is a wart on a finger and how do I know it's not something else?
A wart on a finger is typically a rough, small growth caused by a virus, but you can't reliably tell by looking. Calluses, other benign growths and some skin cancers can look similar. A dermatologist or other licensed clinician should examine anything that is changing, bleeding, itching, irregular or not healing.
How do I get rid of warts?
Wart removal is usually approached in one of three ways: waiting, over-the-counter products, or in-office care from a clinician. Results vary, and warts can come back. Ask a provider which option may suit you, and don't cut, burn or dig out a wart at home.
What is the difference between a wart vs. callus?
A callus is thickened skin from pressure or friction, while a wart is a viral growth. They can look alike, and the two can even occur together. A clinician can tell them apart with an exam, which matters because the care can differ.
How long do warts last?
There is no single timeline, because how long warts last differs from person to person. Some fade by themselves, while others stay for a long time or return after clearing. A provider can talk with you about what to expect and when it might be worth treating.
