About 2,141 of the babies in this group were at least 1 year old in February. But only 1,450 (68 percent) had received follow-up care to check for possible health problems that had been reported to the surveillance network, the researchers said.
“If a mother tests positive for Zika during pregnancy, it’s critical to share her test results with the baby’s doctors after birth so appropriate care can be provided,” Honein said. “Some health problems can easily go undetected, which is why it’s so important these babies receive all the recommended care and evaluation, even if they appear healthy.”
This is the largest report so far on longer-term outcomes among babies born to mothers infected with Zika, Honein said.
The study was published Aug. 7 in the CDC’s Vital Signs report.
