Congenital Syphilis: Preliminary 2020 Data

Preliminary CDC data show nearly 2,100 cases of newborn syphilis in 2020.

This report presents preliminary congenital syphilis data for infants born in 2020 in the context of larger trends observed for syphilis (all stages) among women of reproductive age (15‒44 years) and congenital syphilis over the prior decade (2010‒2019). These data reflect cases reported to CDC through the National Notifiable Diseases Surveillance System (NNDSS) as of 7/29/2021. These data are considered preliminary as 2020 congenital syphilis data will continue to be reported to CDC through fall of 2021. When released, the 2020 STD Surveillance Report will provide final congenital syphilis data for infants born in 2020 and will supersede the data presented in this preliminary report. Until that time, the most comprehensive data for chlamydia, gonorrhea, and syphilis is available from the STD Surveillance 2019 webpage.
