Zika Birth Defects Surveillance
The Zika Birth Defects Surveillance system rapidly identifies and tracks birth defects that might be related to Zika virus infection during pregnancy.
Goals of the Zika Birth Defects Surveillance System
The Zika Birth Defects Surveillance system complements the US Zika Pregnancy and Infant Registry by monitoring infants with birth defects that might be associated with Zika virus infection, regardless of their laboratory tests. This system collects information on infants that the Registry might miss if the mother’s Zika virus infection during pregnancy was not detected.
Ultimately, this information can help identify the types of birth defects that occur in infants who were exposed to Zika virus. The information will serve as a foundation to better understand the long-term effects of Zika virus on a community over time. An evidence-based understanding of these effects will help healthcare professionals recognize potential symptoms of Zika virus infection, and connect families to appropriate medical and social services they need as early as possible.

Rapidly Tracking Birth Defects
CDC supports 50 state, territorial, and local health departments for Zika Birth Defect Surveillance. This includes some departments that are establishing new systems as well as those that are enhancing previously established birth defect surveillance systems. All of these systems find and collect secure medical information about babies born with microcephaly and other birth defects linked to Zika virus infection during pregnancy. This allows the systems to capture secure medical information about a large population of babies at birth without needing to track the growth and development of these babies after birth.
To find birth defects potentially reated to Zika, these areas use a standard case definition to rapidly collect information on all infants who have these birth defects. A standard case definition helps programs collect data in a consistent, systematic way to help ensure that data collected from various geographic areas can be compared in a meaningful way.
Monitoring Health Outcomes
The Zika Birth Defects Surveillance system monitors birth defects potentially related to Zika virus infection, including
- Brain abnormalities
- Eye defects
- Hearing loss
- Other problems associated with damage to the brain that affects the
- Bones (such as clubfoot or inflexible joints)
