Mortality Associated With Congenital Syphilis in the United States, 19921998

--> Objective. To summarize national trends in the incidence of congenital syphilis (CS) and associated mortality.
Methods. We analyzed CS surveillance data reported to the Centers for Disease Control and Prevention by 50 states and the District of Columbia from 19921998.
Results. From 19921998, 942 deaths, including 760 stillbirths, were reported among 14 627 cases of CS, yielding a case fatality ratio (stillborns and deaths/all cases) of 6.4%. Untreated, inadequately treated, or undocumented treatment of syphilis during pregnancy accounted for 87.4% of reported cases. Among CS cases, there was an inverse relationship between the number of prenatal care visits (0, 14, 59,
10) and risk of fatal outcome. Among deaths, 52% of deliveries occurred by 30 weeks gestation. Among live born infants with CS, death occurred more often in infants for whom no radiograph or cerebrospinal fluid evaluation was reported. Although both cases and deaths from CS declined from 19921998, there was no significant change in the case fatality ratio.
Conclusion. Mortality associated with CS continues to be an important public health problem that will resurge if adult syphilis rates increase. Because a large proportion of deaths occur at low gestational age, earlier diagnosis and treatment of maternal syphilis may substantially reduce the case fatality ratio.
