Sexually transmitted diseases (STDs) issues?


Doctor, I would like to ask if I have a viral wart on my foot.
I have read that although they are both caused by HPV, the strains are different.
If I touch the wart and then touch my genitals, is there a risk of infection leading to genital warts?

Kevin, 20~29 year old female. Ask Date: 2019/06/06

Hello: Theoretically, there are over a hundred types of viral warts, and each type prefers specific skin areas.
However, I personally recommend treatment, and it's important to wash your hands frequently after contact to prevent the virus from spreading.
It's not good for yourself or others.
Wishing you good health.

More Info


Human Papillomavirus (HPV) is a complex virus with over 100 different types, some of which are associated with warts, while others are linked to various cancers. The types of HPV that cause common warts on the feet (such as HPV types 1, 2, and 4) are generally not the same as those that cause genital warts (primarily HPV types 6 and 11). However, it is important to understand the transmission dynamics and risks associated with HPV.

When it comes to the question of whether HPV warts on the feet can spread to the genitals, the risk is relatively low but not entirely absent. HPV is primarily transmitted through direct skin-to-skin contact. If you have warts on your feet and you touch them, then touch your genital area without washing your hands, there is a theoretical risk of transferring the virus. However, the types of HPV that typically cause foot warts are not the same as those that cause genital warts, which means that while the virus can potentially be transferred, the likelihood of causing genital warts is minimal.

To further elaborate, HPV types that cause plantar warts (on the feet) are generally not associated with the types that cause genital warts. The immune response to different HPV types can vary, and the skin in the genital area is different from the skin on the feet. This difference in skin type and the specific HPV strains involved means that while there is a possibility of transmission, it is not a common route for the types of HPV that lead to genital warts.

In terms of prevention and risk management, here are some recommendations:
1. Hygiene Practices: Always wash your hands thoroughly after touching any warts, whether on your feet or elsewhere. This is a simple yet effective way to reduce the risk of transferring any virus to other parts of your body.

2. Avoid Direct Contact: Try to avoid touching your feet and then touching your genital area without washing your hands in between. This reduces the risk of any potential transmission.

3. Use Protection: If you are sexually active, using condoms can help reduce the risk of HPV transmission, although they do not provide complete protection since HPV can infect areas not covered by a condom.

4. Vaccination: Consider getting the HPV vaccine if you are eligible. The vaccine is effective against the most common high-risk and low-risk HPV types, including those that cause genital warts and cervical cancer. It is recommended for both males and females, ideally before the onset of sexual activity, but it can still be beneficial later in life.

5. Regular Check-ups: If you have concerns about HPV or any warts, it is advisable to consult a healthcare provider. Regular check-ups can help monitor any changes and provide peace of mind.

In conclusion, while the risk of spreading HPV from foot warts to the genital area is low, it is not impossible. Maintaining good hygiene, avoiding direct contact, and considering vaccination are effective strategies to mitigate the risk of HPV transmission. If you have any further concerns or symptoms, it is always best to consult with a healthcare professional for personalized advice and management.
