1.
Hello Doctor, I have a question.
My colleague has a viral wart, but he has already undergone cryotherapy twice, and the doctor told him to just observe it afterward.
However, the area where he was treated has not completely healed, and there is another suspected viral wart on his palm that has been flat for about 1-2 months, only looking white inside.
He grabbed my arm for about 4-5 seconds, and I have a small cut on my arm that has already healed and scabbed over.
Given this contact, what is the likelihood of me getting infected with the viral wart? (Considering the cut is already healed, does it count as a potentially infected wound?)
2.
If I were to get infected with a viral wart, is there a chance of being contagious before any symptoms appear? Is the contagiousness high before any symptoms manifest?
3.
Is it possible for me to be infected and not show any symptoms, and then after masturbation, transmit the infection to my genital area, resulting in genital warts? Or is the chance of hand warts infecting the genital area low because they are different viruses?
4.
I am currently worried that I might have been infected through this contact and that I could touch other areas of my skin, including my genitals, before any symptoms appear.
Should I deliberately avoid touching other areas, including during masturbation, or is it okay to remain calm and not avoid touching other areas since there are no symptoms?
5.
If one hand has a viral wart but I wash both hands together, will the other hand become infected with the viral wart during the washing process?
6.
I read online that contact between wounds can transmit syphilis, but I am unsure if my colleague's wound included small cuts.
If I have acne on my cheek or small cuts from shaving, will touching someone else's skin with a wound lead to syphilis infection? (The contact time was about 3-4 seconds.)
7.
Do I need to get a blood test because of the acne on my cheek or small cuts from shaving that came into contact with someone else's wound? Or is such contact unlikely to result in infection?

Dr. Hong Yuanbin reply Internal Medicine


Viral warts must be assessed through a direct examination of the skin condition, and it is not possible to answer hypothetical questions regarding your colleague's situation.
It is recommended that if you have any abnormal skin conditions, you seek consultation with a dermatologist.

Understanding the risks associated with warts and sexually transmitted infections (STIs) is crucial for maintaining your health and well-being. Let's address your questions one by one.

1. Risk of Infection from Contact with Warts: The likelihood of contracting the human papillomavirus (HPV), which causes warts, through brief contact with a person who has warts is relatively low, especially if the wart has been treated and is healing. However, if you had a cut or abrasion on your skin, even if it was healing, there is a potential risk for transmission. HPV can enter through broken skin, but the risk is significantly reduced if the wart is not actively shedding virus particles. It’s important to monitor your skin for any changes and consult a healthcare provider if you notice any new growths.

2. Asymptomatic Transmission of Warts: HPV can indeed be transmitted even when there are no visible symptoms. This means that a person can be contagious before they show any signs of warts. However, the risk of transmission is generally higher when warts are present and active. If you are concerned about potential exposure, it may be wise to discuss this with a healthcare professional who can provide guidance based on your specific situation.

3. Transmission to Genital Areas: The risk of transferring the virus from hand warts to the genital area is low, but not impossible. Different strains of HPV are responsible for common warts (usually on the hands and feet) and genital warts (often referred to as condyloma or "cauliflower" warts). While the strains that cause hand warts are not typically the same as those that cause genital warts, it is still advisable to maintain good hygiene practices, especially after touching any warts.

4. Hygiene Practices: If you are worried about potential infection, it is a good idea to practice good hygiene. Washing your hands thoroughly after touching any area that may have been exposed to warts is essential. While it is not necessary to avoid touching other parts of your body, including during masturbation, maintaining cleanliness can help reduce any risk of transmission. If you notice any new growths or changes in your skin, consult a healthcare provider.

5. Washing Hands with Warts: When washing your hands, the act of scrubbing with soap and water is effective in removing viruses, including HPV. If one hand has warts and you wash both hands, the risk of transferring the virus to the other hand is minimal, especially if you are using soap and water effectively. However, it is still wise to avoid touching other areas of your body until your hands are clean.

6. Risk of Syphilis Transmission: Syphilis is primarily transmitted through direct contact with syphilis sores, which are usually found on the genitals, anus, or mouth. The risk of transmission through brief contact with a small cut or pimple is very low, especially if the other person does not have an active syphilis sore. However, if you are concerned about potential exposure, it is prudent to consult a healthcare provider for advice and possible testing.

7. Testing for STIs: If you have concerns about potential exposure to STIs, including syphilis, it is advisable to get tested. While casual contact with small cuts or acne is unlikely to result in transmission, it is always better to err on the side of caution. A healthcare provider can guide you on the appropriate tests based on your risk factors and exposure history.

In summary, while the risks of contracting warts or STIs through casual contact are generally low, maintaining good hygiene practices and being aware of your body are key to preventing infections. If you have any concerns or notice any changes in your skin or health, do not hesitate to reach out to a healthcare professional for personalized advice and testing.
