Scottish nurse Pauline Cafferkey first flew out to Sierra Leone in November 2014 to work at the Ebola Treatment Centre in Kerry Town, six months after the outbreak was identified in the African country.

She returned to Glasgow a month later but the morning after her flight from Heathrow she was admitted to Gartnavel Hospital after feeling feverish.

Ms Cafferkey was quickly placed into isolation before being transferred in a quarantine tent with a flight bound for the Royal Free Hospital in north London.

Treatment from an experimental drug went "very smoothly" and the Cambuslang woman received a visit from her family on New Year's Day.

Her condition then deteriorated into a critical state for almost a fortnight, before she made a full recovery and was discharged from the hospital on January 24.

Several months later, on October 9 last year, the 39-year-old fell ill again and was taken back to the Royal Free Hospital, where doctors discovered she had contracted meningitis caused by the Ebola.

Her condition was described as "critically ill" and she was believed to be fighting for her life. Despite a "significant improvement" in her condition she was kept in London for another few weeks.

In November, it was reported she made a full recovery and was transferred to a Glasgow hospital before returning home to South Lanarkshire.

Despite making two previous recoveries from complications of the disease, in February 2016 she again became unwell and was transferred to London for a third time.

She was taken into Queen Elizabeth University Hospital on Tuesday in a stable condition before making her flight to London in a Royal Air Force plane.
