1.
If a woman has genital warts or HIV, and there is contact with areas not covered by a condom, such as the base of the penis or the scrotum, can washing with water prevent infection?
2.
If I kiss a woman with genital warts (where her tongue or oral cavity has warts), will there be a risk of infection from tongue-to-tongue contact? Thank you.

Andy: Hello! 1.
If there are no wounds or broken skin, immediately washing the area with soap and water can reduce the chance of infection.
Although the risk is low, it cannot be completely avoided.
Therefore, it is recommended to follow up with a medical institution for relevant examinations.
Generally, monitoring should continue for at least 3 months (sometimes due to longer incubation periods, follow-up may be needed for over a year).
2.
There is a possibility of infection.
Recent medical reports have found a correlation between the occurrence of oropharyngeal cancer and human papillomavirus (HPV).
Note: HPV is associated with skin warts, genital warts, and cervical cancer.
If there are any unclear points, feel free to ask again for further discussion and research.
Online responses can only serve as a reference; it is still necessary to seek medical attention at a healthcare facility.

Hsu Wei-Kai, Director of the Urology Department at Taitung Hospital, Ministry of Health and Welfare, who cares about your health.

When it comes to understanding the risks of HPV (Human Papillomavirus) and HIV (Human Immunodeficiency Virus) transmission during sexual encounters, it's essential to consider the modes of transmission and the specific circumstances of each encounter.

1. Risk of Infection from Skin Contact: If a female partner has genital warts (caused by HPV) or is HIV positive, and there is contact with areas of the male anatomy that are not covered by a condom (such as the shaft of the penis, the base, or the scrotum), there is still a risk of transmission. HPV is primarily transmitted through skin-to-skin contact, and even if the areas are washed afterward, the virus can still be present on the skin and may lead to infection. Washing with water may reduce the viral load but does not guarantee complete removal of the virus. For HIV, while the risk is lower compared to direct exposure through unprotected intercourse, there is still a potential risk if bodily fluids (such as pre-ejaculate or vaginal secretions) come into contact with mucous membranes or open cuts.

2. Kissing and HPV Transmission: Engaging in deep kissing (French kissing) with a partner who has HPV-related lesions in their mouth or throat can also pose a risk of transmission. HPV can infect the oral cavity and throat, leading to oropharyngeal cancers. If the partner has visible warts or lesions in their mouth, there is a risk that the virus can be transmitted through saliva or direct contact with the lesions. The likelihood of transmission through kissing is generally considered lower than through sexual intercourse, but it is not negligible, especially with high-risk HPV types.


Additional Considerations:
- Condom Use: While condoms significantly reduce the risk of transmission for both HPV and HIV, they do not provide complete protection against HPV because the virus can be present on areas of skin not covered by the condom. For HIV, condoms are highly effective when used correctly and consistently, but any exposure to infected bodily fluids can still pose a risk.

- Vaccination: The HPV vaccine is effective in preventing the most common high-risk strains of HPV that can lead to cervical cancer and other HPV-related cancers. Vaccination is recommended for both males and females before they become sexually active.

- Regular Screening: Regular screening for sexually transmitted infections (STIs) is crucial for sexually active individuals, especially if engaging in high-risk behaviors. For women, Pap smears can help detect changes in cervical cells caused by HPV, while men can benefit from regular check-ups to monitor for any signs of STIs.

- Communication and Testing: Open communication with sexual partners about STI status and history is vital. If there is any concern about potential exposure to HIV or HPV, it is advisable to seek medical advice and consider testing. Early detection and treatment can significantly improve health outcomes.

In conclusion, while washing exposed areas may reduce the risk of infection, it does not eliminate it entirely. Engaging in sexual activities with partners who have known infections carries inherent risks, and understanding these risks can help individuals make informed decisions about their sexual health. Regular testing, vaccination, and safe sex practices are essential components of reducing the risk of HPV and HIV transmission.
