Syphilis can have serious consequences for your baby. You can lose the baby at any point in the pregnancy, or the baby can be born alive and die shortly after birth. If the baby is infected, the baby can have problems such as jaundice, low blood count, be too small or have infection in the brain. If you are pregnant and have syphilis you must be treated as soon as possible to prevent your baby from getting sick. After you have the baby, the baby must be tested as soon as possible and treated too.
