Ebola Nurse Cafferkey Now 'Critically Ill'

Pauline Cafferkey, the nurse being treated for Ebola, has "deteriorated" and is "critically ill", says the Royal Free Hospital. Ms Cafferkey contracted the disease after treating patients in Sierra Leone at the height of the outbreak, which has killed more than 11,000 people. She was first treated at the Royal Free Hospital in December and discharged in January.
