A British man who contracted the Ebola virus in Sierra Leone, identified as William Pooley, has arrived in the UK on board an RAF jet.
The healthcare worker landed at London’s RAF Northolt in a specially-equipped C-17 aircraft and has been transported to an isolation unit at the Royal Free Hospital in north London.
The man is “not currently seriously unwell”, a Department of Health spokesman said.
Health officials have stressed the risk to the UK remains “very low”.
The DoH said the decision to return the patient to the UK was taken following “clinical advice”.
Prof John Watson, DoH deputy chief medical officer, said they would be taken in a specially-adapted ambulance to a high level isolation unit – the only unit of its kind in the UK.
It is the first confirmed case of a Briton contracting the virus during the current outbreak, in which 1,427 people have died.
The World Health Organization has estimated 2,615 people in West Africa have been infected with Ebola since March.
A statement from Sierra Leone’s health ministry said the Briton had been volunteering at a clinic in the Kenema district of the country.
Sidie Yayah Tunis, director of communications at the health ministry, said the patient had been flown out of the country’s main airport in the town of Lungi on Sunday.
Dr Paul Cosford, director for health protection at Public Health England, said the man was being transferred with “all appropriate protocols promptly activated” by UK health agencies.
“Protective measures will be strictly maintained to minimise the risk of transmission to staff transporting the patient to the UK and healthcare workers treating the individual,” he said.
He added: “UK hospitals have a proven record of dealing with imported infectious diseases and this patient will be isolated and will receive the best care possible.”
