Hello, there is a research unit that has previously cultured the human papillomavirus (HPV) on a mouse from an internet café.
I am not sure how long HPV can survive outside the body; you might want to consult an infectious disease specialist for that.
However, considering that HPV is much more prevalent than HIV, it is likely that it survives longer than HIV does.
The penile mucosa refers to the redder epithelium of the glans and foreskin.
The anal mucosa also refers to the redder areas.
I am not aware of reports from abroad, and there are no statistics available in clinical practice.
I also do not know how one would determine exposure to the virus.
Furthermore, HPV does not easily grow on intact skin (such as on the hands).
You have asked a lot of questions that I cannot answer.
To give you a perspective, the probability of infection is used for medical research to assess entire communities or populations and does not apply to individuals.
For example, if I tell you that the chance of infection in a certain scenario is one in a hundred million, but unfortunately, that person is you, would you still say the chance is very low? My advice is that if you have any doubts, get tested as soon as possible.
If you are infected, seek treatment promptly; do not focus on the probability or have a mindset of luck.
Although HPV is easily treatable, it is also highly contagious and should rank among the top sexually transmitted infections in the country.

More Info

Understanding the transmission risks of Human Papillomavirus (HPV) is crucial, especially in the context of sexual services and potential exposure to the virus. HPV is primarily transmitted through direct skin-to-skin contact, particularly during sexual activities, including vaginal, anal, and oral sex. The virus can infect the genital area, anus, and even the mouth and throat, leading to various health issues, including genital warts and cancers.

Transmission Risks
1. Hand-to-Genital Contact: If a sex worker has come into contact with an infected area (e.g., genital warts) and then touches another client, there is a potential risk of transmission. However, HPV does not survive long outside the human body, and washing hands with soap and water significantly reduces the risk of transmitting the virus. While HIV can be more resilient outside the body, HPV is less likely to be transmitted through indirect contact like this.

2. Infected Individuals: A sex worker who is already infected with HPV poses a higher risk of transmission compared to one who is not infected. If the sex worker has visible warts (condyloma acuminata), the risk of transmission increases, especially if there is direct contact with the infected area.

3. Survival of HPV: HPV does not survive well on surfaces or in liquids. Therefore, the use of massage oils or lotions does not typically facilitate the survival of the virus. The virus requires direct contact with mucous membranes or broken skin to establish an infection.

Infection Pathways
- Intact Skin: Generally, intact skin is a barrier to HPV infection. The virus typically requires access to mucosal surfaces or broken skin to infect an individual.

- Mucous Membranes: Areas such as the urethra, vagina, anus, and oral cavity are more susceptible to HPV infection. The risk is higher if there are micro-abrasions or injuries in these areas.

- Injured Skin: If there are cuts or abrasions on the skin or mucous membranes, the risk of HPV infection increases significantly.

Specific Areas of Concern
- Penile Mucosa: The term "penile mucosa" refers to the inner lining of the penis, including the glans (the tip) and the urethral opening. Both areas are susceptible to HPV.

- Anal Mucosa: The anal mucosa includes both the external and internal surfaces of the anus. Both areas can be infected by HPV, especially during anal intercourse.

Prevalence and Immune Response
Research indicates that a significant portion of the adult population may be exposed to HPV at some point in their lives, with estimates ranging from 50% to 80%. However, the majority of individuals (approximately 90%) will clear the virus naturally within two years due to their immune response. This high clearance rate is attributed to the body's ability to recognize and eliminate the virus before it can cause any significant health issues.

Recommendations
1. Vaccination: The HPV vaccine is highly effective in preventing the most common and high-risk strains of the virus. It is recommended for both males and females, ideally before they become sexually active.

2. Regular Screening: For sexually active individuals, regular screenings (such as Pap smears for women) can help detect any abnormalities early, allowing for timely intervention.

3. Safe Practices: Using condoms can significantly reduce the risk of HPV transmission, although they do not provide complete protection since HPV can infect areas not covered by a condom.

4. Communication: Open discussions with sexual partners about health status and history can help mitigate risks associated with HPV and other sexually transmitted infections.

In conclusion, while the risk of HPV transmission exists in various sexual contexts, understanding the mechanisms of transmission and employing preventive measures can significantly reduce the likelihood of infection. If there are concerns about potential exposure or symptoms, consulting a healthcare provider for testing and guidance is advisable.
