Syphilis Screening in Jails & Prisons: Urgent Call to Protect Pregnant Individuals & Babies

The potential for preventable birth defects and newborn deaths linked to syphilis is prompting renewed calls for improved screening practices, particularly within carceral settings. Researchers at the Institute for Global Health and Infectious Diseases are highlighting a critical gap in current national guidelines: the lack of consistent third-trimester syphilis testing for pregnant individuals in U.S. Jails and prisons. Their recent operate, published in the Journal of Correctional Health Care, details a case where a single late-pregnancy test likely averted congenital syphilis, a potentially devastating condition for newborns.

Congenital Syphilis: A Rising Concern

Congenital syphilis occurs when a mother passes the sexually transmitted infection (STI) to her baby during pregnancy. The Centers for Disease Control and Prevention (CDC) reports a disturbing trend: cases have more than tripled in recent years, with nearly 4,000 reported in 2024 – the highest number since 1994. This surge underscores the urgent need for effective prevention strategies.

Syphilis is caused by the bacterium Treponema pallidum, and while easily curable with antibiotics like benzathine penicillin and doxycycline in its early stages, untreated infection can have severe consequences. The World Health Organization (WHO) notes that maternal syphilis can lead to miscarriage, stillbirth, prematurity, low birth weight, or congenital infection in 50% to 80% of cases. Babies born with congenital syphilis can experience a range of health problems, including deformed bones, severe anemia, and neurological damage.

The Carceral System: A Vulnerable Population

Pregnant individuals within the carceral system – jails and prisons – face unique challenges to accessing adequate prenatal care. These facilities often have limited healthcare resources, high rates of staff turnover, and logistical hurdles that can delay or prevent timely screening and treatment. The study published in the Journal of Correctional Health Care illustrates how a single, strategically timed test in the third trimester can make a significant difference. The researchers found that without this late-stage screening, a case of congenital syphilis would have almost certainly occurred.

Current national screening guidelines generally recommend syphilis testing during the first prenatal visit and again in the third trimester. However, implementation within correctional facilities is often inconsistent. The study authors argue that a more robust and standardized approach is needed, specifically emphasizing the importance of third-trimester testing, even for individuals who have previously tested negative.

Diagnostic Challenges and the Need for Innovation

Diagnosing syphilis can be complex. As noted by Arlene Seña, MD, MPH, of the Institute for Global Health and Infectious Diseases, syphilis is often called “the great masquerader” as its symptoms can mimic other diseases. This diagnostic difficulty is compounded by the disease’s progression through distinct phases, each with different clinical characteristics. Syphilis frequently co-exists with other STIs, such as genital herpes and HIV, adding to the complexity of diagnosis and management.

Adding to the challenge, current diagnostic methods largely rely on serological tests developed in the early 1900s. Researchers have struggled to successfully culture the Treponema pallidum bacterium in a laboratory setting, hindering the development of more advanced and accurate diagnostic tools. The need for improved diagnostic methods is a key area of ongoing research.

Beyond Screening: Prevention and Treatment

While screening is crucial, it’s only one piece of the puzzle. Effective prevention strategies include consistent and correct condom use. The WHO emphasizes that condoms are the best way to prevent syphilis and many other STIs. Pregnant women should be tested for syphilis at their first prenatal care visit and promptly treated if the result is positive. Congenital syphilis can be prevented by administering injectable benzathine penicillin to the mother.

The rise in syphilis cases isn’t limited to the U.S. Globally, the infection is increasing, making prevention, testing, and treatment a growing priority for public health organizations. In April 2024, STI awareness month, health officials are sounding the alarm about the importance of addressing this escalating public health concern.

What Comes Next: Strengthening Surveillance and Refining Guidance

The findings from the Institute for Global Health and Infectious Diseases study are likely to fuel further discussion among public health officials and correctional healthcare providers. A key next step will be to review and potentially revise national screening guidelines to explicitly address the needs of pregnant individuals in carceral settings. Enhanced surveillance within correctional facilities will likewise be critical to track syphilis prevalence and monitor the effectiveness of screening and treatment programs. Further research into improved diagnostic methods and treatment strategies remains a priority.
