Prevention and elimination of mother to child transmission of syphilis
Project Summary
Mother-to-child transmission of syphilis is a consequence of undiagnosed, untreated, or inadequately treated maternal syphilis, and can result in a number of adverse pregnancy outcomes (APOs): late foetal loss, stillbirth, low birth weight, neonatal death, or an infant with reactive serology and clinical symptoms and signs (classically called "congenital syphilis").
WHO estimates that 1.3 million pregnant women annually have active syphilis infection, resulting in a substantial burden of preventable morbidity and mortality including over 200,000 stillbirths and foetal losses and over 90,000 neonatal deaths
We work closely with WHO to strengthen the evidence base to reach the global goal of eliminating mother to child transmission of syphilis.
