Pauline Cafferkey readmitted into isolation unit

Traces of Ebola have been detected in a Scots charity worker who first contracted the virus in December last year.

Pauline Cafferkey has been flown to Royal Free Hospital in London.

She first contracted the virus while helping to fight Ebola in Sierra Leone for the aid charity Save the Children.

There is no update on her condition, however government sources say her transfer to the specialist unit was a "highly precautionary" move.

It comes just after the nurse and aid worker received an award at the Pride of Britain ceremony recognising the risks aid workers took with their own health.

Cafferkey contracted Ebola working as a volunteer with Save the Children at a treatment centre in Kerry Town, in Sierra Leone.

She was diagnosed on 29 December last year, after returning to Glasgow via London.

Her temperature had been tested seven times before she flew from Heathrow to Glasgow and she was cleared to travel, before later falling ill.

After her recovery Cafferkey faced a ‘fitness to practise’ by the Nursing and Midwifery Council but was cleared.

More than 11,000 people in West Africa died during this outbreak but last week was the first time since March 2014 there were no new outbreaks.

The World Health Organisation says research about the long-term implications after having Ebola is not known.
