Reporting and Surveillance
CDC has several surveillance systems for collecting information about Zika virus, its spread, its effects during pregnancy, and its effect on infant outcomes.
US Zika Pregnancy RegistryEnhanced surveillance system for US pregnant women with lab evidence of Zika and their infants up to 1 year old
Puerto Rico Zika Active Pregnancy Surveillance SystemActive surveillance system for pregnant women with lab evidence of Zika and their infants up to 3 years old in Puerto Rico
Birth Defects SurveillanceSurveillance to collect information about babies born with microcephaly and other birth defects that might be linked to Zika infection during pregnancy
Importance of Collecting Surveillance Data About Zika Virus and Its Effects
Data collected through surveillance systems are used to
- Track the spread of Zika in the United States and territories
- Address questions about timing, risk, and the spectrum of outcomes linked with Zika during pregnancy
- Update recommendations for clinical care
- Plan for services for pregnant women and families affected by Zika virus
- Connect families to local health and social services in their community
- Improve prevention of Zika virus infection during pregnancy
Additional Pregnancy Surveillance
Proyecto Vigilancia de Embarazadas con Zika (VEZ)
Proyecto Vigilancia de Embarazadas con Zika (VEZ) is a surveillance project in areas of Colombia with the highest number of Zika-infected pregnant women. In collaboration with Colombia’s Instituto Nacional de Salud and the Colombia Ministry of Health, CDC hopes to better understand the full range of potential health problems that Zika virus infection in pregnancy may cause, and the time of pregnancy when infection poses the highest risk to the fetus.
Pregnancy Risk Assessment Monitoring System (PRAMS)
The Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing population-based surveillance system that monitors self-reported maternal behaviors and experiences before, during, and after pregnancy. This system collects information among women who deliver a live-born infant in participating US states and New York City. PRAMS developed a special supplement for states to monitor Zika virus testing among pregnant women in the first and second trimesters of pregnancy; prenatal counseling about Zika; and practices among pregnant women to reduce or prevent the chances of getting Zika through mosquito bites or sexual transmission.
Zika Postpartum Emergency Response (ZPER) Survey
The Zika Postpartum Emergency Response (ZPER) Survey is a population-based rapid assessment of maternal behaviors and experiences related to Zika virus exposure among women who recently gave birth in Puerto Rico. The ZPER uses methods from previous hospital-based surveillance conducted by PRAMS. This information will be used to understand Zika-related concerns of pregnant women; interactions between women and their healthcare providers regarding Zika; sources of information that women consult regarding Zika; adherence to recommended precautions by pregnant women to reduce their risk of exposure to Zika; and pregnancy intentions.
All Cases of Zika Infection
ArboNET is a national arboviral surveillance system managed by CDC and state and territorial health departments. ArboNET collects information on laboratory-confirmed Zika virus disease cases reported from US states and territories, including Puerto Rico, the US Virgin Islands, and American Samoa.
