Outcomes for Completed Pregnancies in the United States and District of Columbia, 2016-2017

{*} As of January 10, 2017

___

  • What these numbers show
    • The number of completed pregnancies with or without birth defects include those that ended in a live birth, miscarriage, stillbirth, or termination.
    • The number of liveborn infants and pregnancy losses with birth defects include those among completed pregnancies with laboratory evidence of possible Zika virus infection that have been reported to the US Zika Pregnancy Registry.
    • These numbers rely on reporting to the US Zika Pregnancy Registry and may increase or decrease as new cases are added or information on existing cases is clarified. For example, CDC cannot report the number of completed pregnancies with or without poor pregnancy outcomes that have not yet been reported to the US Zika Pregnancy Registry.
    • The number of liveborn infants and pregnancy losses with birth defects are combined for the 50 US states, and the District of Columbia. CDC is not reporting individual state, tribal, territorial or jurisdictional level data to protect the privacy of the women and children affected by Zika. CDC is using a consistent case inclusion criteria to monitor brain abnormalities and other adverse pregnancy outcomes potentially related to Zika virus infection during pregnancy in the US states and territories. Puerto Rico is not using the same inclusion criteria; CDC is not reporting numbers for adverse pregnancy outcomes in the territories at this time.
    • Birth defects reported include those that have been detected in infants infected with Zika before, during, or shortly after birth, including microcephaly, calcium deposits in the brain indicating possible brain damage, excess fluid in the brain cavities and surrounding the brain, absent or poorly formed brain structures, abnormal eye development, or other problems resulting from damage to brain that affects nerves, muscles and bones, such as clubfoot or inflexible joints, and confirmed hearing loss.
  • What these new numbers do not show
    • These numbers are not real time estimates. They reflect the outcomes of pregnancies with any laboratory evidence of possible Zika virus infection reported to the US Zika Pregnancy Registry as of 12 noon Tuesday the week prior. Additionally, there may be delays in reporting of pregnancy outcomes from the jurisdictions.
    • Although these outcomes occurred in pregnancies with laboratory evidence of possible Zika virus infection, we do not know whether they were caused by Zika virus infection or other factors.
  • Where do these numbers come from?
    • These data reflect pregnancies reported to the US Zika Pregnancy Registry(https://www.cdc.gov/zika/hc-providers/registry.html). CDC, in collaboration with state, local, tribal and territorial health departments, established this system for comprehensive monitoring of pregnancy and infant outcomes following Zika virus infection.
    • The data collected through this system will be used to update recommendations for clinical care, to plan for services and support for pregnant women and families affected by Zika virus, and to improve prevention of Zika virus infection during pregnancy.
    • The US Zika Pregnancy Registry and the Puerto Rico Zika Active Pregnancy Surveillance System are covered by an assurance of confidentiality(https://www.cdc.gov/od/science/integrity/confidentiality/). This protection requires us to safeguard the information collected for the pregnant women and infants in the registries.
