Skin warts are common, benign growths caused by the human papillomavirus (HPV). While usually harmless, they can be uncomfortable and sometimes embarrassing. Understanding what causes warts, how they spread, and how to prevent them is essential for skin health.
What Are Skin Warts?
Skin warts are rough, raised growths that appear on different parts of the body. There are several types:
- Common warts — often found on hands
- Plantar warts — on the soles of feet
- Flat warts — smooth, smaller, often on the face or legs
- Filiform warts — thread-like, usually around the face
- Periungual warts — around fingernails and toenails
What Causes Skin Warts?
Warts develop when the HPV virus infects the top layer of skin, usually through small cuts or abrasions. Not everyone exposed to HPV develops warts — a strong immune system often fights the virus off.
How Do Warts Spread?
- Direct skin-to-skin contact with a wart
- Touching objects used by someone with warts (e.g., towels, razors)
- Skin trauma that allows HPV entry
- Public spaces like swimming pools and locker rooms
Wart Prevention Tips
- Avoid touching warts — don’t pick or scratch them
- Keep skin clean and dry
- Don’t share personal items like towels or nail clippers
- Cover cuts and abrasions
- Wear flip-flops in public showers or pool areas
- Wash hands thoroughly after contact
When to See a Doctor
- If warts become painful, bleed, or grow rapidly
- If you’re unsure if a growth is a wart
- If warts spread or recur frequently
- If you have a weakened immune system
Conclusion
While skin warts are generally harmless, they can be unsightly and contagious. By understanding their causes and practicing good prevention, you can keep your skin healthy and reduce the risk of spreading warts.
