"Two American aid workers infected with Ebola are getting an experimental drug so novel it has never been tested for safety in humans.
Dr Kent Brantly, 33, is being treated at an isolation unit at Atlanta's Emory University Hospital, and Nancy Writebol, 59, was expected to be flown there on Tuesday.
They were infected while working in Liberia, one of four west African nations dealing with the world's largest Ebola outbreak.
On Monday, the World Health Organisation said the death toll had risen from 729 to 887 deaths in Guinea, Sierra Leone, Liberia and Nigeria, and more than 1600 people had been infected."
