Syphilis is an infection that is completely preventable and treatable. Syphilis can be passed onto your baby if you do not get treated, this is known as congenital syphilis. If you're pregnant and have syphilis, get treated right away.  

Planning Pregnancy

Get screened. It is important to get screened before pregnancy for not only syphilis, but all other sexually transmitted infections to prevent any transmission of infections to your baby.  

Avoid substance use. Any consumption of alcohol, drugs, or smoking can harm your baby which can lead to miscarriages, and stillbirth.  

Ask your partner to get tested and treated. If you or your partner had syphilis, reinfection can occur if both you and your partner have not been treated. All medication must be taken, even if you think the signs or symptoms are completely gone. After treatment, both you and your partners should wait 7 days to continue any sexual activity.  

During Pregnancy

Seek Prenatal Care. Prenatal care is important to both you and your baby's health. Your provider can monitor both of your health throughout your pregnancy.

Get Tested. Pregnant people should be tested regularly to prevent passing any infections to the baby at: 
  • first prenatal screening 
  • third trimester (28 weeks), and 
  • at delivery
If you have new partners, have had sex with untreated partners, or have symptoms of syphilis, inform your provider right away.

Get Treated. Pregnant people with syphilis need to be treated right away to prevent passing syphilis to your baby. The required treatment is benzathine penicillin G 2.4 million units IM. Depending on the stage of syphilis, treatment may require 3 injections at 1-week intervals. Failure to complete treatment exactly 7 days apart will be considered inadequate and will have to restart treatment series. For any questions, you have regarding treatment, please reach out to your health care provider.

Labor & Delivery

Continue to Get Tested. At delivery, both you and your baby should be tested to make sure syphilis has not been passed to your baby.  

After the Baby is Born

Follow-Up Testing: Complete follow up testing for both parent and baby. 

Treatment: Evaluative tests may be performed to ensure the baby’s health is not impacted by any exposure to syphilis. Newborns born to parents with untreated syphilis or abnormal evaluative results will receive treatment.  

Follow-Up Care: Regular follow-up appointments for both the parent and baby are important to monitor parent and child health, to ensure treatment is effective, and to address any questions or concerns.
