Are there reports of birth defects from Zika Virus Infection in the U.S.?
There are documented reports of birth defects linked to Zika virus infections in the United States. These cases often involve infants born to mothers who had a confirmed or possible infection during pregnancy.
What the research says
A U.S. registry specifically tracks pregnancies and infants with suspected or confirmed Zika infections. This registry has recorded various individual birth defects associated with the virus 3.
Research indicates that Zika virus is a significant concern for pregnant women because it can cause severe consequences for the fetus. These complications include microcephaly, which is a condition where a baby's head is significantly smaller than expected 6. Other reported conditions linked to congenital Zika syndrome include brain calcifications, small head size (microcephaly), enlarged ventricles (ventriculomegaly), and low birth weight 7. Additionally, some children with possible prenatal exposure to the virus have been diagnosed with autism spectrum disorder 2.
