Description

Warts are small, rough skin growths caused by infection with human papillomavirus (HPV), which triggers the top layer of skin to grow rapidly. They can appear anywhere on the body and vary in appearance depending on their location and the specific HPV strain involved.

Causes

Infection with one of the many strains of human papillomavirus (HPV), typically entering the skin through a small cut or break.

Prevention

Avoid direct contact with warts (yours or others'), don't share towels or nail tools, and keep feet dry in public showers or pool areas.

Treatment Options

Over-the-counter salicylic acid, in-office cryotherapy (freezing), cantharidin, or minor surgical removal for stubborn warts.

Myths vs. Facts

Myth: Warts are caused by touching toads or frogs. Fact: They're caused by a virus (HPV) spread through skin-to-skin contact or contaminated surfaces.

When to See a Dermatologist

If a wart doesn't respond to OTC treatment, spreads, is painful, or you're unsure whether a growth is actually a wart.
