A Scottish nurse rushed into hospital under police escort has tested negative for the Ebola virus.

Pauline Cafferkey was taken to hospital on Thursday morning after falling ill at her home in Cambuslang, South Lanarkshire.

She was then taken by ambulance to Queen Elizabeth University Hospital in Glasgow, where she was monitored by the infectious diseases team.

On Thursday evening, NHS Greater Glasgow and Clyde issued a statement saying the 40-year-old had tested negative for Ebola and remained in a stable condition.

It's the fourth time she was been taken into hospital since returning from Sierra Leone in 2014.

A spokeswoman for the health board said: "Pauline Cafferkey was admitted to the Queen Elizabeth University Hospital this morning under the care of the Infectious Diseases Unit.

"Due to Ms Cafferkey's past medical history, appropriate precautionary measures were taken whilst further investigations were carried out.

"We are pleased to report that tests for the Ebola virus are negative. She remains in a stable condition in the Queen Elizabeth University Hospital.

"We want to repeat our previous reassurance that there is no risk to the public."

The latest incident comes after she was cleared of misconduct by the Nursing and Midwifery Council last month.

She was cleared over allegations she "potentially put the public at risk" as she passed through screening at Heathrow on arrival from Sierra Leone in late 2014.

Ms Cafferkey was among a group of doctors and nurses returning to Heathrow on December 28, 2014, after a six-week deployment to the west African country.

The nurse volunteered to help tackle the Ebola crisis at its height, travelling to Sierra Leone to help the afflicted and dying.

She was screened seven times in total for the symptoms of Ebola and allowed to return home but, after developing a high temperature, she contacted the Infectious Diseases Unit at Gartnavel Hospital in Glasgow.

Once in hospital, blood samples soon confirmed her doctor's worst fears. After surviving the disease she fell ill on a number of occasions, which was linked to her previous diagnosis with Ebola.
