[录音原文]
The current Zika outbreak began a year ago in Brazil. It has since spread widely through the Americas. Besides causing babies to be born with underdeveloped brains, Zika also causes immune system disorders, spinal cord inflammation, brain inflammation, as well as multiple sclerosis. The first vaccine could be ready for human trials in September 2016.
