The Queensland nurse at the centre of last week's Ebola scare has warned the world must do 'so much more' to stop the deadly virus before it gets out of control. Sue Ellen Kovack, 57, said it was a 'huge relief' to be released from Cairns Hospital early on Monday morning, after she tested negative for the illness for a second time. Ms Kovack had recently returned from working as a volunteer nurse in Sierra Leone when she came down with a fever last week.
