the Risks of HPV Transmission in Public Spaces

Questions about cauliflower transmission?

Hello, doctor.

Q1: Recently, I found online that some doctors say that besides public restrooms, handles in public places, escalators, elevator buttons, etc., can harbor the HPV virus.
Does this mean we are exposed to HPV every day? I found that if there are any cuts on the skin, even on the hands, HPV can enter the body through these wounds.
I have dermatitis, and my skin is prone to itching, often leading me to unconsciously scratch my fingers, the back of my hands, and even my arms while sleeping, resulting in large areas of broken skin (some people even think I self-harm).
My wounds are so painful that they hurt even when exposed to air, let alone when in contact with water.
Therefore, I rarely use alcohol to disinfect my hands, as it causes me significant pain.
Am I at a high risk of contracting HPV when I go out? (I can't just wrap my hands like a mummy, can I?)
Q2: How long can HPV survive outside the human body? Some urologists say it lasts only 30 minutes, while others say 2 hours, 4-5 hours, or even more than a day, lasting up to 2-3 days.
How long can HPV actually survive? Does the virus die once the bodily fluids or secretions containing HPV dry up, or can it continue to survive in the dried secretions?
Q3: Yesterday, I went shopping at a convenience store, and while reaching for my wallet, I accidentally dropped my phone on the floor.
There were people behind me, so I quickly picked it up and put it in my bag.
I want to ask, if the person in front of me had just come out of the convenience store restroom and stepped on secretions from an HPV-infected person, wouldn't they have brought HPV to the checkout area? If my phone touched the ground, wouldn't it have been contaminated with HPV? After touching my phone, I went to grab my purchased items, which means those items might also be contaminated with HPV.
Since I couldn't disinfect with alcohol while out, and I can't wash my purchased items or phone, I'm feeling very anxious.
I feel like everything I've touched is contaminated with HPV.
I even worry that the soles of my shoes, which I wear at home with my family, are contaminated with HPV, as we don't take off our shoes indoors.
I can't disinfect everything in front of my family (I would be scolded for being neurotic).
So, doctor, how long can HPV survive outside the human body? This is really important to me because I have wounds all over.
If it can survive for several hours or even more than a day, then if that person really stepped on HPV yesterday, am I now living in an environment contaminated with HPV? I know I may sound neurotic, but because I have so many wounds that could allow viruses and bacteria to invade, I really appreciate your help, doctor.
Thank you.

Understanding the risks of HPV transmission, especially in public spaces, is a valid concern, particularly for individuals with compromised skin integrity. Let's address your questions systematically.

Q1: Are we constantly exposed to HPV in public places?
While it is true that HPV can be present in various public environments, the actual risk of transmission through surfaces like doorknobs, escalator handrails, or elevator buttons is extremely low. HPV is primarily transmitted through direct skin-to-skin contact, particularly during sexual activities. The virus does not survive long outside the human body. Although some studies suggest that HPV can remain viable for a short time on surfaces, the conditions must be ideal—warm and moist—for any significant survival time.
Given your situation with skin issues, it is crucial to maintain good hygiene practices. While it may be uncomfortable, you should try to clean your hands regularly, especially after touching public surfaces. Using a gentle hand sanitizer that does not irritate your skin could be beneficial.
Q2: How long can HPV survive outside the body?
The survival time of HPV outside the human body is a topic of some debate among medical professionals. Generally, HPV does not survive long in the environment. Research indicates that HPV can remain viable for a few hours to a couple of days under optimal conditions, such as in a warm, moist environment. However, once the virus is exposed to air and dries out, its viability decreases significantly.
It is important to note that while HPV can be found in bodily fluids, the virus does not remain infectious once those fluids dry. Therefore, if you were to come into contact with dried bodily fluids, the risk of transmission is negligible.
Q3: What about contamination from surfaces?
Your concern about your phone and other items coming into contact with HPV is understandable. If someone had HPV on their shoes and walked through a public space, the likelihood of transferring the virus to the ground and then to your phone is very low. HPV is not easily transmitted through inanimate objects. The virus requires direct contact with mucous membranes or broken skin to enter the body effectively.

If you drop your phone on the ground, the risk of HPV transmission is minimal, especially if you wash your hands afterward before touching your face or any mucous membranes. It’s also worth noting that the virus does not persist long on hard surfaces, particularly if they are dry.

Conclusion:
Given your skin condition, it is wise to be cautious, but it is also essential to balance that caution with an understanding of the actual risks involved. HPV transmission through indirect contact in public spaces is highly unlikely. Maintaining good hygiene practices, such as washing your hands frequently and avoiding touching your face, will significantly reduce any potential risk.
If you have ongoing concerns about HPV or your skin condition, consider consulting a healthcare provider who can offer personalized advice and reassurance. Regular check-ups and discussions about vaccination (like the HPV vaccine) can also help mitigate risks associated with HPV. Remember, while it’s good to be vigilant, excessive worry can lead to unnecessary anxiety.
