The second UK patient to be diagnosed with the deadly Ebola virus has arrived in Hampstead for treatment.

Pauline Cafferkey, a Scottish nurse who contracted the virus while volunteering in west Africa, was transferred from Glasgow in a military-style aircraft.

The Royal Free Hospital in Pond Street confirmed this morning it had received Ms Cafferkey, who is being treated in its high level isolation unit.

She had been working in Sierra Leone with charity Save the Children and was in isolation in hospital in Glasgow since yesterday morning.

She is said to be in a stable condition.

It comes after the Royal Free successfully treated the country’s first known case of Ebola.

William Pooley spoke of the “world class care” he received after being evacuated from Free Town, Sierra Leone, by RAF aircraft on August 24.

A volunteer nurse, Mr Pooley was treated with experimental drug ZMapp which uses natural proteins to isolate and neutralise the invading Ebola pathogens.

He was a keen test subject for the drug, which is still in its initial trial stages.

Supply of the drug is low and was only made available to the hospital due to one of its director’s clinical contacts.

This morning, the hospital would not comment on whether it had secured more batches of the drug or whether it had taken blood from a healthy Mr Pooley for treatment of future patients.
