Congenital syphilis is a sexually transmitted infection that can be passed from a pregnant person to their fetus. It is caused by the bacteria Treponema pallidum and, if untreated, may result in major health issues. is brought on by the bacteria Treponema pallidum and, if untreated, can have dangerous effects. In this article, you will learn about the etiology, epidemiology, clinical manifestations, diagnosis, treatment and management, prevention and screening of congenital syphilis.
Etiology of Congenital Syphilis Congenital syphilis is caused by the transmission of the bacterium Treponema pallidum from a pregnant person to their fetus. This can occur at any stage of pregnancy and can result in a range of adverse outcomes for the fetus, including stillbirth, neonatal death, and a range of physical and neurological abnormalities. The risk of transmission and severity of outcomes is highest when the pregnant person has untreated syphilis.
Key Takeaways
- Congenital syphilis is a serious sexually transmitted infection that can be passed from a pregnant person to their fetus.
- The bacterium Treponema pallidum is responsible for causing congenital syphilis.
- Congenital syphilis can result in a range of adverse outcomes for the fetus, including stillbirth, neonatal death, and a range of physical and neurological abnormalities.
Etiology of Congenital Syphilis
Congenital syphilis is caused by the bacterium Treponema pallidum, which is transmitted from an infected mother to her fetus during pregnancy or delivery. The risk of transmission is highest during the early stages of syphilis infection, particularly during the first two years of maternal infection.
The transmission of T. pallidum can occur through the placenta, by direct contact with the infectious lesions during delivery, or through contact with infected genital secretions during delivery. The risk of transmission is higher in women with primary and secondary syphilis, as opposed to those with latent syphilis.
The severity of congenital syphilis depends on the stage of maternal infection, the duration of infection, and the adequacy of maternal treatment. Infants born to mothers with untreated or inadequately treated syphilis are at higher risk of developing severe manifestations of congenital syphilis, including stillbirth, neonatal death, and serious long-term sequelae.
The clinical manifestations of congenital syphilis can vary widely, ranging from asymptomatic infection to severe multisystem disease. The most common manifestations include hepatosplenomegaly, jaundice, anemia, rash, and bone lesions. Other possible manifestations include neurosyphilis, interstitial keratitis, and Hutchinson teeth.
the bacteria Treponema pallidum, which is transferred from an infected mother to her foetus during pregnancy or birth, is the cause of congenital syphilis. The severity of congenital syphilis depends on the stage of maternal infection, the duration of infection, and the adequacy of maternal treatment. Infants born to mothers with untreated or inadequately treated syphilis are at higher risk of developing severe manifestations of congenital syphilis.
Epidemiology
Congenital syphilis is a preventable disease that occurs when a mother with untreated syphilis passes the infection to her fetus during pregnancy or delivery. According to a review of global epidemiology, the incidence of congenital syphilis varies widely across countries and regions, with the highest burden in low- and middle-income countries, particularly in sub-Saharan Africa and Southeast Asia. In the United States, the incidence of congenital syphilis has been increasing since 2012, with a 261% increase in reported cases from 2012 to 2020 .
The first prenatal checkup, the third trimester, and during delivery are the times when the Centres for Disease Control and Prevention (CDC) advise all expectant mothers to get tested for syphilis. delivery if they are at high risk for infection. High-risk women include those with a history of syphilis or other sexually transmitted infections, those living in areas with high syphilis rates, and those who use illicit drugs or exchange sex for money or drugs .
Prevention of congenital syphilis requires early detection and treatment of maternal syphilis. The CDC recommends that all infants born to mothers with syphilis be evaluated and treated for congenital syphilis, regardless of maternal treatment status. Infants with congenital syphilis may have a variety of clinical manifestations, including rash, hepatosplenomegaly, anemia, and neurologic abnormalities .
In addition to timely diagnosis and treatment of maternal syphilis, other strategies for preventing congenital syphilis include increasing access to prenatal care, improving syphilis screening and treatment among pregnant women, and promoting safer sexual practices among women of reproductive age .
Overall, the epidemiology of congenital syphilis highlights the importance of comprehensive prenatal care and effective public health interventions to prevent and control the spread of syphilis and other sexually transmitted infections.
Clinical Manifestations
Congenital syphilis can present with a variety of clinical manifestations that depend on the stage of the disease. The clinical features of congenital syphilis can be divided into early and late presentations.
Early Signs
Early signs of congenital syphilis can occur within the first few weeks of life and may include:
- Skin rash, which can be widespread and involve the palms and soles of the feet
- Mucous membrane lesions, which can occur in the mouth, nose, and anus
- Hepatosplenomegaly, which is the enlargement of the liver and spleen
- Lymphadenopathy refers to the growth of lymph nodes.
- Hematological abnormalities, such as anemia and thrombocytopenia
- Skeletal abnormalities, such as periostitis and osteochondritis
Late Presentation
Late presentation of congenital syphilis can occur months or years after birth and may include:
- Hutchinson teeth, which are notched and widely spaced permanent teeth
- Saddle nose, which is a flattened bridge of the nose
- Keratitis interstitial: inflammation of the cornea
- Eighth nerve deafness, which is a hearing impairment
- Clutton joints, which are painless symmetrical joint effusions
- Saber shins, which is a bowing of the legs
It is important to note that not all infants with congenital syphilis will present with clinical manifestations. Infants who are asymptomatic at birth may still have laboratory abnormalities, such as a positive serologic test for syphilis or abnormal cerebrospinal fluid (CSF) findings. Therefore, all infants born to mothers with syphilis should be evaluated and treated appropriately.
Diagnosis
If you suspect that you or your child may have congenital syphilis, it’s important to seek medical attention right away. Your doctor will perform a physical exam and may order laboratory tests or imaging studies to confirm the diagnosis.
Laboratory Testing
The most common laboratory test used to diagnose congenital syphilis is a blood test that looks for antibodies to the bacterium that causes syphilis. This test can be done on a sample of blood taken from the mother during pregnancy or from the baby after birth. If the test is positive, further testing may be needed to determine the stage of the infection and the appropriate treatment.
Other laboratory tests that may be used to diagnose congenital syphilis include a spinal tap to look for the bacterium in the cerebrospinal fluid and a bone scan to check for bone abnormalities.
Imaging
Imaging studies such as X-rays, ultrasounds, and CT scans may also be used to help diagnose congenital syphilis. These tests can be used to look for bone abnormalities, such as those that may occur in late-stage syphilis, or to check for other complications of the infection.
- If you suspect that you or your child may have congenital syphilis, it’s important to seek medical attention right away. With prompt diagnosis and treatment, the outlook for children with congenital syphilis is generally good.
Treatment and Management
If you are pregnant and have syphilis, it is important to get treated as soon as possible to prevent congenital syphilis in your baby. According to the the recommended treatment for pregnant women with syphilis is penicillin. Penicillin is safe for both you and your developing baby. Your healthcare provider will determine the appropriate dosage and duration of treatment based on your stage of syphilis.
If you are diagnosed with syphilis during pregnancy, your baby will also need to be treated to prevent congenital syphilis. The treatment for congenital syphilis depends on the stage of the disease. According to the , the recommended treatment for infants with congenital syphilis is a 10-day course of intravenous penicillin G.
It is important to note that early diagnosis and treatment of syphilis during pregnancy is crucial to prevent congenital syphilis. Therefore, it is recommended that all pregnant women get tested for syphilis during their first prenatal visit. If you are at high risk of syphilis, your healthcare provider may recommend additional testing during your pregnancy.
In addition to treatment, proper management of syphilis during pregnancy is also important. This may include close monitoring of your baby’s health, such as regular ultrasounds, and follow-up testing to ensure that the treatment is effective. Your healthcare provider may also recommend that you avoid sexual activity until the infection has been treated to prevent reinfection.
Prevention and Screening
Preventing congenital syphilis is crucial to ensure the health of both the mother and the newborn. The best way to prevent congenital syphilis is to prevent syphilis in pregnant women. Therefore, it is essential to screen all pregnant women for syphilis as early as possible.
The World Health Organization (WHO) recommends that all pregnant women should be screened for syphilis at their first antenatal visit. If a pregnant woman tests positive for syphilis, she should receive immediate treatment with penicillin. According to a study by WHO, antenatal screening for syphilis is cost-effective and can prevent fetal deaths due to congenital syphilis.
It is also important to screen pregnant women who are at high risk of syphilis infection, such as those who have multiple sexual partners or who live in areas with a high prevalence of syphilis. Moreover, it is recommended to retest women who are at high risk of syphilis infection during the third trimester of pregnancy, at delivery, and in the postpartum period.
In addition to antenatal screening, it is also important to promote safe sex practices and increase awareness about the risks of syphilis infection. This includes promoting the use of condoms, reducing the number of sexual partners, and increasing access to syphilis testing and treatment.
Overall, preventing congenital syphilis requires a comprehensive approach that includes antenatal screening, treatment, and education. By following these guidelines, you can reduce the risk of congenital syphilis and ensure the health of both you and your newborn.

Can congenital syphilis be effectively treated, and what are the treatment options?
Yes, congenital syphilis can be effectively treated with antibiotics, particularly penicillin. Treatment is typically administered intravenously for several days, depending on the severity of the infection. Infants who are treated promptly and appropriately can recover fully from congenital syphilis, although long-term follow-up may be necessary to monitor for potential complications.
What long-term complications can arise from untreated congenital syphilis?
Untreated congenital syphilis can lead to a range of long-term complications, including bone deformities, deafness, blindness, and neurological problems. Some infants may also experience developmental delays or intellectual disabilities as a result of the infection.
How can congenital syphilis be prevented during pregnancy?
Congenital syphilis can be prevented during pregnancy through routine prenatal care and screening. Pregnant women should be tested for syphilis early in pregnancy, and those who test positive should receive prompt treatment to reduce the risk of transmission to the fetus. In addition, pregnant women can reduce their risk of acquiring syphilis by practicing safe sex and avoiding sexual contact with partners who are known to have the infection.
What is the Hutchinson triad, and how is it associated with congenital syphilis?
The Hutchinson triad is a set of symptoms that are sometimes observed in infants with congenital syphilis. The triad consists of three symptoms: 1) interstitial keratitis, which is inflammation of the cornea that can lead to vision loss; 2) notched teeth, which can occur as a result of damage to the developing teeth during fetal development; and 3) deafness, which can result from damage to the inner ear. The Hutchinson triad is a sign of advanced, untreated syphilis and is associated with a poor prognosis.
