This number reflects the number of pregnant women with any laboratory evidence of possible Zika virus infection reported to the Maryland Zika Pregnancy Registry. There may be some delay in reporting cases, so this number is not a real time estimate. This number will be updated every two weeks.

What are the outcomes for these pregnancies?

In Maryland, there have been babies born with anomalies. Out of concern for patient confidentiality, DHMH is not releasing these numbers.
Livebirth anomalies include, but are not limited to, contractured limbs, insufficient cerebrospinal fluid (CSF), skull malformations, and seizures.
Pregnancy losses have also been reported in Maryland, including both miscarriages and voluntary terminations.

What these numbers do not show

Although these outcomes occurred in pregnancies with laboratory evidence of possible Zika virus infection, it is still unclear whether they were caused by Zika virus infection or other factors.

Where do these data come from?

These data result from active surveillance by local health department personnel who investigate reports of Zika virus infection in Maryland residents with a history of travel to an area with active transmission of Zika virus.
Pregnant women who report travel to an area with active Zika virus transmission and who are approved for Zika virus testing are referred to the Zika Pregnancy Registry if they have a test result that suggests Zika virus exposure.
