Warts

Warts are skin growths caused by the human papilloma virus (HPV) and can be removed if they cause discomfort or multiply.

Overview

Warts are growths on your skin caused by an infection with human papilloma virus, or HPV. Types of warts include:

  • Common warts, which often appear on your fingers
  • Plantar warts, which show up on the soles of your feet
  • Genital warts, which are a sexually transmitted infection (STI)
  • Flat warts, which appear in places you shave frequently

Treatment

In children, warts often go away on their own. In adults, they tend to stay. If they hurt or bother you, or if they multiply, you can remove them. Chemical skin treatments usually work. If not, various freezing, surgical and laser treatments can remove warts.

Frequently Asked Questions

Yes, warts are contagious and can spread to other areas of your skin through autoinoculation, which happens when you scratch or pick at a wart and then touch another part of your body. To prevent spreading, avoid touching or picking at warts, keep your nails short, and wash your hands thoroughly after touching a wart. Do not share personal items like towels, razors, or nail clippers with others, as the virus can survive on these surfaces. What is the difference between common warts and plantar warts, and why do plantar warts hurt more?::Common warts usually appear on fingers, hands, or around nails and are rough and raised. Plantar warts develop on the soles of the feet, where body weight presses them inward rather than outward. This pressure causes the wart to grow deeper into the skin, which can lead to pain when walking or standing. Plantar warts often have small black dots, which are clotted blood vessels, and may feel like a pebble in your shoe. Can warts be passed to a sexual partner, and how is this prevented?::Genital warts, caused by specific strains of HPV, are sexually transmitted and can be passed to a partner through skin-to-skin contact, even if no visible warts are present. The most effective prevention method is vaccination against HPV before becoming sexually active. Additionally, using condoms can reduce the risk of transmission, though they do not eliminate it entirely because they do not cover all genital skin. Regular screening and open communication with partners are also important. How long does it take for a wart to go away with home treatment, and when should I seek professional removal?::Home treatments, such as salicylic acid, typically require consistent daily application for several weeks to months to fully remove a wart. You may need to repeat the treatment cycle if the wart persists. Seek professional removal if the wart is painful, growing rapidly, changing color, or if home treatments fail after several months. Professional options include cryotherapy (freezing), electrocautery, or laser treatment, which can be more effective for stubborn or widespread warts.
