Wart Hand

What Are Warts?

Warts develop when human papillomavirus (HPV) enters the skin through tiny cuts or breaks, causing an overgrowth of skin cells. They can appear anywhere on the body and vary in appearance depending on the type of wart and its location.

Warts are contagious, meaning they can spread through direct contact or by touching contaminated surfaces.

What Causes Warts?

Warts are caused by HPV infection, which thrives in warm, moist environments. Risk factors include:

  • Skin trauma or cuts
  • Walking barefoot in public areas
  • Weakened immune system
  • Close skin-to-skin contact
  • Nail biting or picking at skin

Not everyone exposed to HPV develops warts.

Symptoms of Warts

Warts may:

  • Feel rough or firm
  • Appear flesh-colored, white, brown, or gray
  • Be tender or painful (especially plantar warts)
  • Spread to nearby skin
  • Cause cosmetic or functional concerns

Some warts cause no symptoms other than their appearance.

How Are Warts Diagnosed?

Warts are typically diagnosed through a clinical skin examination. In some cases, your dermatologist may:

  • Examine the lesion closely
  • Trim the surface to look for characteristic features
  • Perform a biopsy if the diagnosis is uncertain

How Long Does Wart Treatment Take?

Wart treatment often requires patience and persistence.

  • Some warts resolve after a few treatments
  • Others may require multiple visits over weeks or months
  • Even after successful treatment, recurrence can occur

Are Warts Preventable?

While not all warts can be prevented, risk may be reduced by:

  • Avoid walking barefoot in public areas
  • Keeping skin clean and dry
  • Avoid picking or scratching warts
  • Not sharing personal items (towels, razors)
  • Covering warts to reduce the spread
