Are warts contagious?

Yes, the HPV virus that causes warts is contagious and can spread through direct contact with a wart or surfaces contaminated with the virus. However, the risk of transmission varies and not everyone exposed will develop warts.

Do warts go away on their own?

Many warts eventually go away on their own as the immune system fights the virus, often within one to two years. However, treatment can speed this process and prevent spreading to other areas.

Can you get warts from frogs or toads?

No, this is a common myth. Warts are caused exclusively by human papillomavirus. The bumps on frogs and toads are not warts and cannot transmit HPV to humans.

Warts

Also known as: Verrucae, Common warts, Plantar warts

Warts are benign skin growths caused by the human papillomavirus (HPV) that infects the top layer of skin. They can appear anywhere on the body but are most common on the hands, feet, and face. While warts are generally harmless and may resolve on their own over time, treatment can speed their removal and prevent spreading.

Symptoms

Small, rough, grainy bumps on the skin

Flesh-colored, white, pink, or tan growths

Black dots (clotted blood vessels) on the surface

Plantar warts on the feet that may cause pain when walking

Flat warts appearing in clusters on the face or legs

Cauliflower-like appearance of common warts

Causes

Infection with specific strains of human papillomavirus (HPV)
Virus entering the skin through cuts or breaks
Direct contact with a wart or contaminated surface

Risk Factors

Children and teenagers who have not built immunity
Weakened immune system
Walking barefoot in shared wet areas like pools or locker rooms
Nail biting or picking at hangnails exposing skin to the virus
Damaged or wet skin

Diagnosis

Visual examination of the growth
Paring the surface to look for black dots (thrombosed capillaries)
Skin biopsy in rare cases when the diagnosis is uncertain

Treatment

Over-the-counter salicylic acid preparations
Cryotherapy with liquid nitrogen
Prescription-strength topical treatments
Electrosurgery or curettage
Immunotherapy injections for stubborn warts
Watchful waiting as many warts resolve within two years

Prevention

Avoiding direct contact with warts
Wearing shoes in public showers and pool areas
Not picking at warts to prevent spreading
Keeping skin dry and healthy
HPV vaccination to prevent genital warts

When to See a Doctor

Warts that are painful or change in appearance
Warts on the face or genital area
Warts that do not respond to over-the-counter treatment
Uncertain whether a growth is a wart or something else
