Purpose of review: In light of alarming increases in the incidence of congenital syphilis in many middle and higher income countries across the globe, this review summarizes recent changes in the epidemiology of syphilis, highlights recommended changes to testing in pregnancy and provides an update for the management of syphilis infection in pregnancy (SIP) and of the infant born to a mother with SIP.
Recent findings: The re-emergence of congenital syphilis is a result of increasing infectious syphilis in women of childbearing age, which is in turn a result of increasing syphilis in the general population particularly in Indigenous and marginalized populations. Potential reasons for the increase include changing sexual practices and increased travel and migration, as well as factors that limit healthcare access, particularly access to antenatal care and limited awareness and education amongst mothers and maternity services. A single antenatal test for syphilis is insufficient; more frequent testing in pregnancy is necessary even for women deemed to be low risk. The management of SIP and of the newborn is complex and guidelines should be readily available with clear recommendations.
Summary: Congenital syphilis is preventable. The current crisis calls for a global and national multipronged, co-ordinated approach involving public health and hospital systems which includes education of individuals and healthcare workers, availability of updated guidelines for prevention and treatment, prioritization of antenatal testing, assurance of accessible and prompt treatment and appropriate assessment and follow-up of infants.
