Can You Get Syphilis from Unprotected Sex with a Healthy Partner?

Questions regarding sexually transmitted infections (STIs)?

If both partners are healthy and have a monogamous relationship, is there still a risk of contracting syphilis or other sexually transmitted infections (STIs) if they engage in unprotected sexual intercourse? Thank you, doctor.

If both partners are healthy and in a monogamous relationship, engaging in unprotected sexual intercourse still carries a risk of contracting syphilis and other sexually transmitted infections (STIs).
However, if both partners are healthy and use condoms during sexual activity, the risk of transmitting syphilis and other STIs is significantly reduced.

When it comes to sexually transmitted infections (STIs) like syphilis, the risk of transmission is influenced by several factors, even if both partners are considered "healthy." The term "healthy" typically means that neither partner has been diagnosed with an STI at the time of sexual activity, but it does not account for potential asymptomatic infections or recent exposures that may not yet be detectable.

1. Understanding Syphilis Transmission: Syphilis is primarily transmitted through direct contact with syphilitic sores, which can occur during vaginal, anal, or oral sex. If both partners are truly free of syphilis and have been tested recently, the risk of transmission is low. However, if one partner has been exposed to syphilis or has an undiagnosed infection, engaging in unprotected sex can lead to transmission.

2. Asymptomatic Carriers: It's important to note that many STIs, including syphilis, can be asymptomatic in the early stages. This means that a person can carry the infection without showing any signs or symptoms. Therefore, even if both partners feel healthy, there is still a risk if one partner has been exposed to syphilis or another STI.

3. Regular Testing: For sexually active individuals, especially those with multiple partners or those who engage in unprotected sex, regular STI testing is crucial. This helps ensure that any infections are caught early and treated promptly. The Centers for Disease Control and Prevention (CDC) recommends that sexually active individuals get tested at least once a year, and more frequently if they have multiple partners or engage in high-risk behaviors.

4. The Role of Condoms: Using condoms significantly reduces the risk of STI transmission, including syphilis. While they are not 100% effective (as they do not cover all areas that might come into contact with sores), they provide a substantial barrier against many infections. Therefore, even in a monogamous relationship, using condoms can be a wise choice, especially if there is any uncertainty about either partner's STI status.

5. Communication and Trust: Open communication between partners about sexual health, testing history, and any concerns regarding STIs is essential. Both partners should feel comfortable discussing their sexual history and any potential risks involved in their sexual practices.

6. Conclusion: In summary, while the risk of contracting syphilis from unprotected sex with a healthy partner is lower if both partners have been tested and are free of STIs, it is not zero. Regular testing, open communication, and safe sex practices are vital components of maintaining sexual health. If there are any concerns about potential exposure or symptoms, it is advisable to consult a healthcare provider for testing and guidance.
