A new study in primates raises the possibility that children infected with the Zika virus during infancy could be at risk of experiencing brain damage. Zika is known to destroy developing brain tissue when it infects a fetus in the womb. Scientists know less about how the virus might affect the brain of an infant infected after birth.
In the new study, scientists infected rhesus macaques with Zika virus at the age of about 1 month — which corresponds to about 3 months of age in a child. The macaques showed troubling brain and behavioral changes.
