Are warts contagious?

Yes, the causative viruses can be transmitted through skin contact or moist floors. Good hygiene reduces the risk.

Do warts disappear on their own?

Often yes, especially in children. However, this can take months, and some warts require treatment.

Why do warts keep coming back?

The viruses can remain in the skin, and reinfection is possible. This is why warts sometimes recur repeatedly.

Warts — Causes, Assessment & the Right Specialty

Warts are benign skin growths caused by viruses that occur mainly on the hands and feet. They are harmless, but can be bothersome or painful on the soles of the feet. Many warts disappear on their own over time, but some require targeted treatment.

Possible causes

Wart viruses (HPV)

Certain human papillomaviruses enter through small skin injuries and stimulate the skin to grow excessively.

Infection

The viruses are transmitted through direct skin contact or via moist floors, such as in swimming pools.

Moist, softened skin

Sweaty feet or small cracks make it easier for the viruses to penetrate the skin.

Weakened immune system

If the immune system is temporarily weakened, warts occur more frequently or persist longer.

Typical steps at the doctor's office

1Your doctor can usually identify a wart by its typical appearance and distinguish it from other skin lesions.
2In unclear cases, the area can be examined more closely or a sample can be taken.
3Treatment depends on the type, location and symptoms, and ranges from watchful waiting to targeted removal measures.

What you can do yourself

Do not scratch or pick at the wart to prevent further spreading.
Wear swimming shoes in swimming pools and communal showers and do not share towels.
Keep feet and hands dry, as moisture promotes spreading.
Wash your hands after touching a wart to protect other areas of skin.

When a doctor's visit makes sense

Medical evaluation is advisable if warts are painful, spread rapidly, keep recurring, or do not disappear despite patience. Professional assessment is also recommended for warts on the face or in the genital area.
