Concerns About Penile Contact with Surfaces: Infection Risks Explained - Urology

The penis comes into contact with the table?


Hello Dr.
Hsu,
I would like to describe a situation that is concerning me: I am a male, and yesterday I was only wearing underwear while answering a phone call in my dining room.
My lower abdomen was resting against a table where I placed the phone, and that table does not seem very clean, as it may have had mice or cockroaches crawling on it.
Since there is an opening in the middle of my underwear for urination, I am unsure if my penis came into contact with the table that may have been crawled on by mice or cockroaches.
If there was contact, I would like to ask you:
1.
Is there a possibility of contracting viruses (such as HIV, HPV, syphilis, etc.)? (There were no visible wounds or bleeding on the penis.)
2.
To your knowledge or experience, have there been any cases of infection resulting from such contact (the penis touching the table)?
Thank you, Dr.
Hsu.

Anonymous: Hello.
1.
The chances are slim.
2.
I personally haven't heard of it.
Note: I once saw a news report about cases of cauliflower infection caused by mouse contact in internet cafes.

When it comes to concerns about potential infections from contact with surfaces, especially regarding sexually transmitted infections (STIs) such as HIV, HPV, and syphilis, it's important to understand the transmission routes of these viruses and the risks involved.

1. Risk of Infection from Surface Contact: In your scenario, where the penis may have come into contact with a table that has been exposed to rodents or insects, the risk of contracting HIV, HPV, or syphilis is extremely low. These viruses are primarily transmitted through direct contact with infected bodily fluids (such as blood, semen, vaginal fluids) or through sexual contact with an infected individual. HIV, for instance, does not survive long outside the human body and is not transmitted through casual contact or surfaces. HPV and syphilis also require direct skin-to-skin contact or contact with infected lesions for transmission to occur.

2. Absence of Open Wounds: Since you mentioned that there were no visible wounds or bleeding on the penis, this further reduces the risk of infection. The skin acts as a barrier to many pathogens, and unless there is a break in the skin or mucous membranes, the likelihood of infection from incidental contact with a contaminated surface is minimal.

3. Cases of Infection from Surface Contact: There are no documented cases of HIV or other STIs being transmitted through contact with surfaces like tables, even if those surfaces have been in contact with pests. Most infections require specific conditions for transmission, and casual contact with surfaces does not meet those criteria.

4. General Hygiene Practices: While the risk in your scenario is low, it is always advisable to maintain good hygiene practices. Regularly cleaning surfaces, especially in areas where food is prepared or consumed, can help minimize exposure to bacteria and viruses. Additionally, washing hands after touching potentially contaminated surfaces and before engaging in any intimate activities is a good practice.

5. Monitoring for Symptoms: If you experience any unusual symptoms, such as sores, rashes, or other signs of infection, it is wise to consult a healthcare provider. They can provide appropriate testing and guidance based on your specific situation.

In summary, the likelihood of contracting HIV, HPV, or syphilis from incidental contact with a table, even if it has been exposed to pests, is exceedingly low, especially in the absence of open wounds. Maintaining good hygiene and being aware of your body are key components of sexual health. If you have ongoing concerns, consider discussing them with a healthcare professional who can provide personalized advice and reassurance.
