Doctors are getting a better look at the workings of zika and microcephaly as it ravages infected fetuses and infants thanks to brain scans and ultrasounds.
A New York Times story showed that better imaging and deeper monitoring of affected babies and mothers is painting a better picture of exactly how the disease impedes brain development. Until now many of the understandings of the disease's functions were very general.
Of course better understanding of the disease may lead to better treatment and even vaccines and cures. But not all the news is good news:
The images, published Tuesday in the journal Radiology, also suggest a grim possibility: Because some of the damage was seen in brain areas that continue to develop after birth, it may be that babies born without obvious impairment will experience problems as they grow.
