Few days after she was transferred from Scotland to north London on an RAF Hercules plane, Pauline Cafferkey, the British nurse who became the first person to be diagnosed with Ebola in the UK is now in a critical condition.

A brief statement on the hospital’s website reads: “The Royal Free London NHS Foundation Trust is sorry to announce that the condition of Pauline Cafferkey has gradually deteriorated over the past two days and is now critical.”

The 39-year-old was part of a team of medical volunteers deployed to Africa by the UK Government last month is being treated using the blood of a recovered patient and an experimental anti-viral drug.

Unfortunately the ZMapp drug used to treat a fellow British volunteer nurse William Pooley who recovered from the disease is according to reports, no longer available in the world.
