Zika virus found in fetal brain

Zika virus found in fetal brain

The Zika virus, thought to be responsible for a surge in birth defects in Brazil, has been found inside the abnormally small brain of an aborted fetus at roughly 29 weeks of gestation, a team of researchers reported Wednesday in the New England Journal of Medicine.

An autopsy of the aborted fetus revealed a brain that had virtually none of the folds and convolutions that would usually be seen on the brain's surface in a fetus at that point in its development. Calcium deposits were evident throughout the brain's white matter--the tissue that connects neurons and brain regions to one another. And in several places, those calcifications displaced developing cortical matter.
