Between December 1, 2015 and March 31, 2018, among pregnancies with laboratory evidence of confirmed or possible Zika virus infection, around 3.1 percent of live-born infants had microcephaly and 1.1 percent some kind of eye abnormality. This graph shows the percentage of U.S. live-born infants, born between 2015 and 2018, from pregnancies with laboratory evidence of confirmed or possible Zika virus infection that had any Zika-associated birth defect, by birth defect.

* From pregnancies with laboratory evidence of confirmed or possible Zika virus infection.
** Infants with birth head circumference below the third percentile based on INTERGROWTH-21st.
Among infants with microcephaly, 141 and 64 also had a birthweight below the 10th percentile (SGA) among pregnancies with laboratory evidence of confirmed
or possible Zika virus infection during pregnancy and NAAT-confirmed Zika virus infection, respectively.
*** Neuroimaging was available for 66.0% and 29.2% of infants with microcephaly only from pregnancies with laboratory evidence of confirmed or possible Zika virus
infection during pregnancy and NAAT-confirmed Zika virus infection, respectively.
