Authorities are trying to trace all 71 passengers on a Heathrow to Glasgow flight who may have been exposed to Ebola.
A woman returning home from Sierra Leone has become the first person in Britain to be diagnosed with the disease.
Britain's screening system for the disease immediately came under scrutiny after the NHS nurse's condition was not detected in either country.
Nicola Sturgeon, Scotland's First Minister, confirmed that a woman was being treated at Gartnavel Hospital in Glasgow after returning to Scotland via London.
She appealed for the public not to panic and said the chances of a wider outbreak were "negligible".
