Little was known about the maternal and fetal/infant effects of Zika infection before the 2015 outbreak in the Americas, which made it challenging for public health practitioners and clinicians to care for pregnant women and infants exposed to Zika. In 2016, CDC implemented a rapid surveillance system, the US Zika Pregnancy and Infant Registry, to collect information about the impact of Zika infection during pregnancy and inform the CDC response and clinical guidance. In partnership with state, tribal, local, and territorial health departments, CDC disseminated information from this surveillance system, which served as the foundation for educational materials and clinical tools for healthcare providers.
Objective: To describe how Zika virus (Zika) surveillance data informs and improves testing guidance, clinical evaluation and management of pregnant women and infants with possible Zika infection
