Are cutaneous warts contagious?

Yes, cutaneous warts are contagious. Warts are caused by an infection with the human papillomavirus (HPV) [1], a virus that can spread from person to person or from one part of the body to another on the same person. Warts can appear on various parts of the body, such as fingers, the soles of the feet, or areas that are shaved frequently [1].

How are cutaneous warts transmitted?

Cutaneous warts are primarily transmitted through direct contact with infected skin. This can occur when touching someone else's wart, or when using shared items like towels or razors that have come into contact with a wart. Warts can also spread from one area to another on the person's own body; for example, if a person scratches a wart and then touches another area of their skin [1].

Types of warts vary depending on the strain of HPV causing them and their location on the body. For example, common warts often appear on the fingers, while plantar warts appear on the soles of the feet [1].

Factors that increase the risk of developing warts

• Weakened immune system: People with compromised immune systems may be more susceptible to warts or may experience them for a longer duration.
• Skin cuts and abrasions: The virus can enter the skin more easily through small cuts or scratches.
• Warm and moist environments: The virus that causes warts thrives in moist environments, making places like shared swimming pools and locker rooms potential sites for infection transmission.

Preventing the spread of warts

To reduce the risk of contracting or spreading warts, certain preventive measures can be taken:

• Avoid touching warts: Whether they are your own or someone else's.
• Do not share personal items: Such as towels, razors, or nail grooming tools.
• Cover warts: If you have warts, cover them with a bandage to prevent spreading the virus, especially during sports or in public places.
• Maintain hand and foot hygiene: Wash hands regularly and dry feet thoroughly.
• Wear sandals in public places: Such as swimming pools and locker rooms, to protect your feet from infection.

When should you see a doctor?

Although warts often disappear on their own, especially in children, they may persist in adults [1]. If warts are painful, multiplying, or causing you discomfort, it is recommended to visit a doctor [1]. A doctor can diagnose the type of wart and provide appropriate treatment options, which may include chemical treatments, freezing (cryotherapy), surgery, or laser therapy [1] [2]. For more information on types of warts and the treatment of hand and foot warts, you can visit Cutaneous Warts: Types and Treatment for Hands and Feet (Arabic).

You should consult a healthcare professional if you notice any signs of infection, such as redness, swelling, or discharge around the wart, or if the wart does not disappear after treatment [2].
