Correct and consistent use of latex condoms can reduce the risk of syphilis when the infected area or site of potential exposure is protected. However, a syphilis sore outside of the area covered by a latex condom can still allow transmission, so caution should be exercised even when using a condom.
The surest way to avoid transmission of sexually transmitted diseases, including syphilis, is to abstain from sexual contact or to be in a long-term mutually monogamous relationship with a partner who has been tested and is known to be uninfected.
Partner-based interventions include partner notification – a critical component in preventing the spread of syphilis. Sexual partners of infected patients should be considered at risk and provided treatment per the 2015 STD Treatment Guidelines. 3
