Viral Warts: Transmission Risks and Hygiene Practices

Transmission of viral warts in different areas and post-contact cleaning?

Hello Doctor: Yesterday, I went to a hair salon and noticed that the hairstylist had a raised lesion on the side of her left index finger (near the thumb) at the joint, approximately one centimeter in diameter, white and yellowish, and quite thick.
While she was adjusting her mask, the lesion brushed against my ear.
I am very concerned that it might be a viral wart.
I asked her if she had seen a doctor, and she said that the lesion has been there for twenty to thirty years, and she trims it herself; it doesn't hurt or bleed, and it reappears after some time.
She insisted that it is not contagious and did not believe what I said.
I have searched extensively online for information and photos about viral warts, trying to convince myself that it might not be one.
I immediately took a shower and washed my ear when I got home, but the more I researched, the more fearful I became, as it really resembles a common wart, and the lesion is quite large.
My questions are as follows:
1.
Many articles mention that viral warts have a limited duration and often resolve on their own, but the lesion on the hairstylist has been there for twenty to thirty years.
Is it possible for a viral wart to persist for that long? I am afraid that it has not only not healed but may have worsened over time.

2.
What are the specific areas where viral warts can be infected? In my case, if I touched the lesion on her hand and then touched my ear, is that direct contact considered dangerous? Is light contact also risky?
3.
I felt very anxious after being touched, and as soon as I got home, I immediately took a shower and washed my ear.
I would like to know, after coming into contact with the lesion, how quickly can the virus establish itself in the cells? Is the effectiveness of washing after "direct contact" significant? Thank you for your response, and I appreciate your help!

Viral warts, commonly caused by the human papillomavirus (HPV), are benign growths that can appear on various parts of the body. Understanding their transmission risks and hygiene practices is crucial, especially in situations like the one you described. Let’s address your concerns systematically.

1. Longevity of Viral Warts: It is indeed possible for viral warts to persist for many years. Some individuals may have warts that last for decades, particularly if they have a type of HPV that is more resistant to the immune response. The immune system plays a significant role in controlling and eliminating HPV infections, but in some cases, the virus can remain dormant or evade the immune response, leading to chronic warts. The fact that the hairdresser has had the wart for 20-30 years suggests that it may be a persistent infection, but it does not necessarily indicate that it is malignant or harmful. However, it is always advisable for individuals with long-standing growths to consult a healthcare professional for evaluation.

2. Transmission Risks: Viral warts are primarily spread through direct skin-to-skin contact. They can also be transmitted indirectly via contaminated surfaces, such as towels or tools. In your case, the potential for transmission occurred when the wart came into contact with your ear. While the risk of transmission through light contact is lower than through direct, prolonged contact, it is not zero. The virus can enter through micro-abrasions or breaks in the skin, which is why maintaining good hygiene is essential.

3. Hygiene Practices and Immediate Actions: Washing the area where contact occurred is a good first step. The virus does not immediately establish an infection upon contact; it typically requires a break in the skin for the virus to penetrate and infect the cells. By washing your ear thoroughly, you reduce the likelihood of the virus adhering to your skin. It is recommended to use soap and water, and if possible, an alcohol-based hand sanitizer afterward for added protection.

4. Preventive Measures: To minimize the risk of contracting warts, consider the following hygiene practices:
- Avoid direct contact with warts on others.

- Do not share personal items like towels, razors, or nail clippers.

- Keep your skin intact and avoid picking at any lesions or warts.

- If you have any cuts or abrasions, cover them with a bandage to prevent potential exposure.

5. Monitoring and Seeking Medical Advice: If you notice any changes in your skin, such as the development of new growths or changes in existing ones, it is advisable to consult a healthcare provider. They can provide a proper diagnosis and treatment options if necessary.
In summary, while the risk of contracting viral warts from a brief contact is relatively low, it is wise to remain vigilant and practice good hygiene. If you have further concerns or develop any symptoms, do not hesitate to seek medical advice. Your health and peace of mind are paramount.
