A British nurse who was twice successfully treated after contracting Ebola in Sierra Leone in 2014 was admitted to the London hospital for a third time. Now, the nurse has been discharged after five days from the Royal Free Hospital.
Pauline Cafferkey was successfully treated within weeks of her diagnosis but suffered a relapse in October 2015, when she became critically ill with meningitis linked to the deadly virus.
Again, she made a full recovery but was admitted for a third time to the Royal Free Hospital, Britain's only isolation ward for Ebola, due to a further unspecified complication.
Experts warn that Ebola can cause ongoing problems in many survivors, although in most cases the problems seem to improve and become less frequent with time.
More than 11,300 people were killed before the World Health Organization declared last month that the two-year Ebola outbreak in west Africa was over, although Sierra Leone has since recorded new cases.
