A literature review published in JAMA Pediatrics describes fetal abnormalities that include microcephaly and other signs and symptoms of what Zika can do to the unborn child.
The study is at: http://jamanetwork.com/journals/jamapediatrics/fullarticle/2579543
The investigative reporting program 60 Minutes took on the subject of Zika last night. It was really well done. The implications of the virus for pregnant women, and what is happening in Puerto Rico, are chilling.
I highly recommend you take a look at all the video segments.
