During the week (30-March-2016), Queensland Health (Queensland is a State wihtin Australia) released its weekly notifiable conditions data, which list ZIKV detections as a distinct entity (looking at you ) and listed Vietnam as the origin of acquisition of the (I presume) case reported by the media.

So we keep watching and hope that Vietnam has plenty of advice coming to it behind-the-scenes from the World Health Organization (who also have not listed it in this weeks ZIKV SitRep ) about how to reduce the risks of the Vietnamese community becoming infected by ZIKV.
