According to the official press release, the new guidance has updated information pertaining to the interpretation of laboratory results for infants as well as infant follow-up care:
- Changes have been made to the recommendations for hearing and vision screening
- Some screenings that had been previously recommended—such as thyroid screening and hearing screening at 4 to 6 months of age—are no longer recommended
- When it comes to infants with CZS-consistent birth defects, providers should “monitor for an expanded list of potential problems” which include issues with breathing and swallowing, as well as hydrocephaly after birth. Furthermore, care and follow-up for these infants is no longer dependent on their Zika virus testing results.
- Infants without birth defects consistent with CZS who were born to mothers with laboratory evidence of possible Zika infection while pregnant “should receive an eye examination by an ophthalmologist.”
- It is no longer routinely recommended that infants without birth defects consistent with CZS who were born to mothers with potential exposure to the virus during pregnancy, but no laboratory evidence of infection, receive “Zika testing and clinical evaluation beyond the standard evaluation and routine preventive care.”
- A review of new data, as well as clarification pertaining to the guidance of prenatal diagnosis, is provided in the updated guidance.
CDC recommends “coordinated care by a multidisciplinary team and an established medical home (an approach to healthcare that helps ensure care is coordinated and infants receive appropriate services)” for infants with CZS, according to the press release. The CDC encourages families
to actively monitor their child, as it is critical for the early identification of any developmental delays that may make themselves known.
As more information is made available, this guidance will be updated.
