Scottish nurse, Pauline Cafferkey, who contracted Ebola while working in Sierra Leone has made a complete recovery and been discharged from hospital.
Ms Cafferkey is now free of the virus after more than three weeks in hospital, where she was critically ill for a time.
A British nurse diagnosed with Ebola after returning to Glasgow from Sierra Leone is in a critical condition, health chiefs have said.
In a statement, Royal Free Hospital in north London said Pauline Cafferkey's condition had deteriorated and she was now considered critical.
Trained nurse Ms Cafferkey, aged 39 from Glasgow, had agreed to blood plasma treatment and an experimental anti-viral drug, despite a lack of proof that it worked.
In a statement on its website, the hospital said:
