The finding strengthens the evidence that a mother's Zika infection during pregnancy raises her baby's risk of microcephaly and other brain malformations. But from January to September 2016, 26 babies out of 442 born to mothers with suspected Zika virus infection during pregnancy showed these defects, according to data from the U.S. Zika Pregnancy Registry. Though the two datasets were collected using different measures and so aren't directly comparable, the findings bolster previous evidence suggesting that certain brain defects appear much more frequently in babies born to Zika-infected mothers. In that timeframe — before Zika appeared in the United States — microcephaly, brain abnormalities or another Zika-associated birth defect appeared in just 3 out of every 1,000 live births.
