Half of Babies Affected by Zika Virus Are Developing Normally by Age 2

July 8, 2019

(New Scientist) – Among a group of about 200 babies born to mothers who had contracted Zika virus, about one third had developmental delays, but not all of them were lasting. About half of the babies with abnormal assessments early in their lives later tested normally on developmental tests around age 2 or 3. Karin Nielsen-Saines at the University of California, Los Angeles, and her colleagues tracked the development of babies born to women who contracted Zika virus in Rio de Janeiro, Brazil during the 2015-2016 epidemic.
