Wearing flip-flops can help prevent warts

Wearing flip-flops or other shoes in moist areas, such as piers, pool decks, and public showers can reduce your risk of developing warts on your feet.

8 precautions that can help prevent warts

It can be difficult to prevent warts completely. The virus that causes warts, human papillomavirus (HPV), is found everywhere. However, by taking some precautions, you can reduce the likelihood of you and your family getting warts.

For fewer warts, make sure everyone in your home follows these dermatologist-recommended precautions:

  1. Avoid touching someone’s wart and wash your hands after treating a wart. HPV is contagious. It’s possible for the virus to get inside your body through a cut or scratch, which can cause a wart.

  2. Clean and cover cuts and scrapes. HPV is everywhere. Covering cuts and scrapes can reduce your chance of HPV getting in and causing a wart.

  3. Make sure that everyone in your home has their own towels, washcloths, razors, nail clippers, socks, and other personal items. If someone in your home has a wart, this helps prevent the virus that causes warts from spreading from one person to another.

  4. Wash your hands often. Because HPV is so common, this helps to remove the virus from your skin.

  5. Prevent dry, cracked skin. When skin is cracked and dry, it’s easier for HPV to slip in through a crack in your skin, which could cause a wart.

  6. Stop nail biting and cuticle chewing. When you bite your nails or cuticles, it causes tears in the skin, including some that are too tiny to see. These openings make it easier for HPV to get inside your body.

  7. Wear flip-flops or pool shoes in locker rooms, pool areas, and public showers. HPV thrives in warm, moist areas. When your skin is moist and soft, it’s easier to get infected with HPV.

  8. Treat hyperhidrosis. This is a medical condition that causes people to sweat excessively. When people sweat frequently, their skin becomes damp and soft. Having damp, soft skin may increase the risk of getting HPV infection, which could lead to a wart.

If you develop a wart

The virus that causes warts is found everywhere, so it may not always be possible to prevent a wart. If you or a family member develops a wart, you may be able to treat it yourself. At-home treatments can effectively treat one or a few small warts.

If the wart doesn’t go away with at-home treatment, the wart appears on your face or genital area, or a wart itches or bleeds, see a board-certified dermatologist. Warts can have a serious impact on your health and well-being. No one understands warts better than your board-certified dermatologist.
