Pauline Cafferkey was initially admitted to Glasgow's Queen Elizabeth University Hospitalbut was later transferred to the Royal Free Hospital here.
A spokesman for the Royal Free said: "We can confirm that Pauline Cafferkey is being transferred to the Royal Free hospital due to a late complication from her previous infection by the Ebola virus. She will now be treated by the hospital's infectious diseases team under nationally agreed guidelines."
Cafferkey was treated at the same hospital twice in 2015 after contracting Ebola in Sierra Leone while working as a nurse at the Save the Children treatment centre in Kerry Town.
Last year, the Royal Free Hospital had said Cafferkey had made a full recovery from Ebola and was no longer infectious.

At one point the Scottish nurse was described as "critically ill" but was discharged and transferred to Queen Elizabeth University Hospital in Glasgow to continue her recovery and later returned home.
