UK Ebola nurse Paula Cafferkey 'in critical condition'

A British nurse who was diagnosed with Ebola after returning from Sierra Leone is now in a critical condition, the London hospital treating her has said.

The Royal Free Hospital said that the condition of Pauline Cafferkey has gradually deteriorated over the past two days.

Ms Cafferkey, from South Lanarkshire, was diagnosed in December after volunteering with Save the Children.
