Scots nurse Pauline Cafferkey is to be flown to London after being admitted to hospital in Glasgow for a third time since contracting Ebola.
The 40-year-old from South Lanarkshire is currently in a “stable” condition at Glasgow’s Queen Elizabeth Hospital.
An RAF Hercules aircraft will later fly her to London where she will be treated at the Royal Free Hospital.
Ms Cafferkey was treated there twice in 2015 after contracting Ebola in Sierra Leone the previous year.
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.
“The Ebola virus can only be transmitted by direct contact with the blood or bodily fluids of an infected person while they are symptomatic so the risk to the general public remains low and the NHS has well established and practised infection control procedures in place.”
NHS Greater Glasgow and Clyde said Ms Cafferkey had been admitted to the Queen Elizabeth University Hospital in Glasgow “under routine monitoring by the Infectious Diseases Unit”.
The health board said she was “undergoing further investigations and her condition remains stable”.
The nurse, from Halfway, Cambuslang, contracted the virus while working as part of a British team at the Kerry Town Ebola treatment centre.
She spent almost a month in isolation at the Royal Free at the beginning of 2015 after the virus was detected when she arrived back in the UK.
Ms Cafferkey was later discharged after apparently making a full recovery, and in March 2015 returned to work as a public health nurse at Blantyre Health Centre in South Lanarkshire.
In October last year it was discovered that Ebola was still present in her body, with health officials later confirming she had been diagnosed with meningitis caused by the virus.
