Are Plantar Warts Contagious? What You Need to Know

Approximately 10% of Americans develop plantar warts at some point in life. These hard, bumpy growths often form on weight-bearing areas, such as the heels and balls of the feet. Plantar warts usually cause mild symptoms, but they can pose more serious risks for people with diabetes or circulatory issues.

At The Foot Institute in Shreveport and Natchitoches, Louisiana, podiatrist Angelo Morreale, DPM, is often asked whether plantar warts are contagious. Here, he explains how plantar warts form, why they’re contagious, and how to prevent their spread.

What are plantar warts?

Plantar warts are small, skin-colored growths on the bottoms of the feet caused by certain strains of the human papillomavirus (HPV). They form when the virus enters small cuts or breaks in the skin. 

Plantar warts don’t always cause problems, but depending on their size and location, they can make standing and walking painful. For people with diabetes or circulatory issues, they may also increase the risk of infection and other complications.

Are plantar warts contagious?

Yes. Plantar warts are contagious and can be spread through skin-to-skin contact or by touching a contaminated surface. For example, public areas such as swimming pool decks, shared showers, and locker room floors provide warm, moist environments for HPV to thrive. 

If you go barefoot in these areas or don’t take other necessary precautions, the virus is more likely to enter your skin and cause warts.

How to prevent the spread of plantar warts

The good news is there’s plenty you can do to reduce your risk of getting plantar warts. Here are a few of our top tips: 

Avoid going barefoot in communal areas

Whenever you’re in a public facility, like a locker room or sauna, wear flip-flops, sandals, or slip-ons on your feet. This is especially important if you’re immunocompromised or have an open wound, like a cut or scratch.

Designate items for individual use

Sharing your towels, socks, or shoes with friends or family members might not seem like a big deal, but these and other high-touch items can spread HPV and increase the likelihood of plantar warts. 

If you have warts, cover them

If you have a plantar wart, cover it with a bandage or medical tape when going barefoot in public spaces. This can prevent viral particles from shedding, keeping surfaces virus-free.

Don’t pick or scratch at warts

Warts shed viral particles, and picking or scratching at them can cause the virus to spread to another part of your body. This can also leave an open wound and increase your risk of a bacterial infection.

When to see a doctor about plantar warts

Small plantar warts typically improve with over-the-counter (OTC) treatments, like salicylic acid and cryotherapy. However, if you have multiple warts or your warts are painful and keep you from moving comfortably, contact our team right away.

After discussing your symptoms and completing a podiatry exam, Dr. Morreale can make personalized treatment recommendations to treat the wart and reduce the risk of spreading the virus, helping you feel better.
