The data are shocking: Almost 35,000 U.S. syphilis cases by mid-July 2022 with the highest rates per/100,000 population in Nevada (n = 21), California (n = 19), and Mississippi (n = 16). Excluding Nevada, California, and Oklahoma, rates over 12/100,000 were concentrated in the southernmost U.S. states. Overall, the 2,268 congenital syphilis cases in U.S. children born in 2021 was a 6% increase over 2020, and a 680% increase over 2012. (Note: All 2021 data are not yet available because of public health STI resources being diverted to COVID-19 control.) A telling number is the 166 congenital syphilis deaths in babies born in 2021 – a 1,000% increase over 2012. Another concern is that 50% of U.S. counties reported at least one congenital syphilis case in 2019 – the last time frame from which county-specific data are available.
Syphilis afflicts the underserved and underprivileged more than other demographic groups, particularly when public health budgets are not adequate (funding for public health STI prevention/treatment efforts has lagged for more than a decade), and/or when public health emergencies such as the pandemic divert public health resources away from STI prevention/treatment efforts.
As pediatric care providers, we can help by heightening our vigilance and appropriately testing for and treating syphilis, particularly in newborns/infants, regardless of where we work. And we can advocate for increased public health STI funding allocation whenever possible. It is a smart economic move because it costs nearly 1,000 times more to manage congenital syphilis and its sequelae than to prevent or treat it.
