Left Graphic: This graphic is a drawing of a baby with birth defects caused by congenital Zika syndrome. Right Graphic: This graphic shows that the number of reported cases of pregnant women with any evidence of possible Zika increased in 2016 from January through December

 

 

Congenital Zika syndrome is a pattern of birth defects in babies infected with Zika during pregnancy.

  • Small head size (microcephaly), problems with vision and hearing, problems moving limbs and body, damage to the brain, seizures, and problems with feeding (difficulty swallowing) are the birth defects related to congenital Zika syndrome

Reported cases of pregnant women with any lab evidence of possible Zika increased in 2016.

Zika can be prevented and managed with proper care.

Prevent

  • Avoid travel to areas with Zika.
  • Talk with your doctor about the risks if you must travel to any areas with Zika.
  • Take steps to prevent getting Zika from sex.
  • Follow steps to prevent mosquito bites.

Screen

  • Screen pregnant women for possible exposure to Zika:
    • Have you traveled to an area with Zika during pregnancy or just before you became pregnant?
    • Have you had sex without a condom with a partner who lives in or traveled to an area with Zika?
    • Do you live in or do you frequently travel (daily or weekly) to an area with Zika?

Test

Who should be tested for Zika?

Pregnant women

  • Who were exposed to Zika through travel or unprotected sex whether or not they report signs or symptoms
  • Living in areas with Zika

Babies

  • Born to mothers with evidence of Zika infection during pregnancy
  • Born to mothers who were possibly exposed to Zika
    • With clinical findings that suggest congenital Zika syndrome regardless of mother’s test results
    • Without abnormalities whose mothers were not tested in the appropriate time frame if there is concern about follow-up for the baby

Manage

If a baby is suspected to have Zika, clinical management should include:

  • Comprehensive physical exam
  • Neurologic exam
  • Eye exam
  • Brain imaging
  • Newborn hearing screening
  • Zika laboratory tests
  • Referral to specialists as needed
