Doctors at a hospital in north-west London have begun treating a Briton who contracted Ebola in Sierra Leone.
William Pooley, a 29-year-old volunteer nurse, was described by a charity he worked for as a "hero".
Mr Pooley was flown to RAF Northolt in a specially equipped military aircraft on Sunday and taken under police escort to Hampstead's Royal Free Hospital.
He volunteered to go to care for victims of the Ebola outbreak which has killed almost 1,500 people.
His is the first confirmed case of a Briton contracting the virus during the current outbreak.

'Remarkable man'
Mr Pooley, believed to be from near Woodbridge in Suffolk, was flown out of Sierra Leone's main airport in Lungi, in a RAF C-17 transport aircraft.
He will be treated in a specialist isolation unit for patients with highly infectious disease, the only one of its kind in Europe.
A special tent ensures medical staff can interact with the patient but are separated by plastic and rubber.
Mr Pooley had worked as a volunteer providing palliative care at The Shepherd's Hospice in Sierra Leone from March until July.
He then requested to be relocated to the Kenema Government Hospital to serve on the Ebola treatment ward, after he heard reports that patients were being abandoned when health workers died from the virus.
Gabriel Madiye, the executive director of The Shepherd's Hospice, said Mr Pooley had been aware of the risks, but was determined to work there.
"We consider him a hero," he said. "Somebody who is sacrificing to provide care in very difficult circumstances - when our own health workers are running away."

There is no cure for Ebola but with treatment of the symptoms, and proper hydration, patients have a chance of survival.
Prof Jonathan Ball, a virologist at Nottingham University, said there would be immediate testing to ensure all organs were functioning.
"He really is in the best place and will have the best possible care," he said.

Whisked into the Royal Free Hospital late on Sunday night under police escort was a man whose noisy arrival was quickly replaced by the everyday comings and goings of a rainy bank holiday morning.
Inside the building a rare drama is unfolding - the meticulous treatment of the first British person infected by the Ebola outbreak.
The volunteer nurse is being treated in an isolation unit which is the only one of its kind in Europe, and more sophisticated than any facility in west Africa.
Doctors will interact with him behind the plastic of an airtight tent to avoid the risk of contamination.
They will attend to his symptoms, particularly dehydration, but Ebola has no proven cure, so the main battle is down to him and his body's ability to fight the virus.

Last week, two Americans who had contracted the disease in Liberia made a recovery and were discharged from hospital after being given an experimental drug called ZMapp in the US.
Officials in Liberia also said three medical staff have shown signs of improvement after taking the drug.
The US manufacturer of ZMapp has said supplies of the drug are exhausted, but the Department of Health said it was working to source any remaining doses.
Department of Health deputy chief medical officer Prof John Watson has said the risk of Ebola to the UK remains "very low".

The World Health Organization has estimated 2,615 people in west Africa have been infected with Ebola since March.
Health officials have reported the first cases outside west Africa, in the Democratic Republic of Congo.
The virus is spread between humans through direct contact with infected bodily fluids. It is one of the world's deadliest diseases, potentially with a mortality rate of 90%. However, the current outbreak has a fatality rate of 55%.

  • Symptoms include high fever, bleeding and central nervous system damage
  • Fatality rate can reach 90% - but current outbreak has mortality rate of about 55%
  • Incubation period is two to 21 days
  • There is no vaccine or cure
  • Supportive care such as rehydrating patients who have diarrhoea and vomiting can help recovery
  • Fruit bats, a delicacy for some West Africans, are considered to be virus's natural host

Ebola crisis: Virus spreading too fast, says WHO

The Ebola outbreak in West Africa is spreading faster than efforts to control it, World Health Organization (WHO) head Margaret Chan has said.
She told a summit of regional leaders that failure to contain it could be "catastrophic" in terms of lives lost.
But she said the virus, which has claimed 729 lives in four West African countries since February, could be stopped if well managed.

It spreads by contact with infected blood, bodily fluids, organs - or contaminated environments.
Initial flu-like symptoms can lead to external haemorrhaging from areas like eyes and gums, and internal bleeding which can lead to organ failure.
Dr Chan was meeting the leaders of the worst-affected countries - Guinea, Liberia and Sierra Leone - to launch a new $100m (£59m; 75m euro) Ebola response plan.

"This meeting must mark a turning point in the outbreak response," Dr Chan said at the summit in Guinea's capital, Conakry.
"Cases are occurring in rural areas which are difficult to access, but also in densely populated capital cities," she said, explaining that the outbreak was the world's deadliest and largest in terms of geographical areas.

Ebola 'kills over 5,000 gorillas'

Scientists fear Ebola and hunting combined could wipe out gorillas


More than 5,000 gorillas may have died in recent outbreaks of the Ebola virus in central Africa, a study
Scientists warn that, coupled with the commercial hunting of gorillas, it may be enough to push them to extinction.
The study, published in the US journal Science, looked at gorilla colonies in Republic of Congo and Gabon. Ebola is also blamed for many chimpanzee deaths.
One of the most virulent viruses known, Ebola has killed more than 1,000 people since it was first recorded in 1976.
Ebola causes viral haemorrhagic fever - massive internal and external bleeding - which can kill up to 90% of those infected.
Scientists are still working on a vaccine and there is no known cure.
Ape-to-ape transmission
The latest study, carried out by an international team, has confirmed previous concerns about how badly the virus is affecting gorillas.

"Add commercial hunting to the mix, and we have a recipe for rapid ecological extinction," the report says. "Ape species that were abundant and widely distributed a decade ago are rapidly being reduced to remnant populations."
The researchers, led by Magdalena Bermejo of the University of Barcelona, focused on western gorillas, one of two gorilla species. The other is the eastern gorilla.
In 2002 and 2003, several outbreaks of Ebola flared up in human populations in Gabon and Congo.
The researchers found a "massive die-off" in gorillas in Congo's Lossi Sanctuary between 2002 and 2004.

"The Lossi outbreak killed about as many gorillas as survive in the entire eastern gorilla species," the study says. The researchers concluded that the apes were not only infected by other species, such as fruit bats, but were also transmitting the virus among themselves.
Ebola was passing from group to group of the endangered animals, they found, and appeared to be spreading faster than in humans.
Outbreaks of the disease in humans have sometimes been traced to the bushmeat trade.
According to World Health Organization figures, Ebola killed 1,200 people between the first recorded human outbreak in 1976 and 2004.
