OK here is the first reply to my asking those that I know in the Public Health field in the South Pacific. Nothing new but they are not ruling out Ebola yet. BTW I didn't mention Ebola at all in my Email to him.

Hello Michael,
I only heard that they became ill after a brief visit to Fiji and it seems like they were exposed to some unfamiliar foreign body that their body system are not familiar with. It can be food poisoning, microorganism such as a virus Ebola?? N if that's the case how in the world they got exposed?? I am thinking worse case scenario...but there is further investigation among CDC, & WHO people, before we know something. I am advising my kids to be careful when they go around n not eating out etc...
