Nurse Pauline Cafferkey, who contracted Ebola while working in Sierra Leone, has been released from isolation after being treated for meningitis caused by the deadly virus.

The 39-year-old, from Blantyre in South Lanarkshire, was re-admitted to the isolation unit at the Royal Free Hospital in north-west London on October 9, months after she was thought to have fought off the infection.

She had contracted Ebola in the west African state last December.

At one point she was described as "critically ill" but the Royal Free has announced that she was discharged from its care on November 11 and transferred to Glasgow's new Queen Elizabeth University Hospital to continue her recovery.

Speaking before she returned to Scotland, Mrs Cafferkey said: "I am forever thankful for the amazing care I have received at the Royal Free Hospital.

"For a second time, staff across many departments of the hospital have worked incredibly hard to help me recover and I will always be grateful to them and the NHS.

"I am looking forward to returning to Scotland and to seeing my family and friends again."

The Royal Free said today Ms Cafferkey had made a full recovery from Ebola and was no longer infectious.

A spokeswoman for the unit said: "We are delighted that Pauline has made a full recovery from Ebola and is now well enough to return to Scotland. We would like to wish her well for the future."

Cafferkey, from South Lanarkshire, first contracted Ebola while working as a nurse at the Save the Children treatment centre in Kerry Town, Sierra Leone.

She was diagnosed in December after returning to Glasgow from the west African country via London.

She spent almost a month in an isolation unit at the Royal Free before being discharged in late January.

Forty people were offered vaccinations after she was found to have fallen ill again with her family claiming doctors "missed a big opportunity" to spot it.
