The British volunteer nurse who has contracted Ebola in Sierra Leone has been named after being evacuated to the UK.
William Pooley, 29, is the first confirmed case of a Briton contracting the virus during the recent outbreak.
He was named by Dr Robert Garry, an American scientist who worked at the same hospital as him in the west Africa country.
Dr Garry said he was told by a university colleague that the test results for Mr Pooley were received in the early hours of Saturday morning.
Mr Pooley was working at a hospice in the capital Freetown but moved to Kenema when he heard that other healthcare workers at KGH had died from Ebola.
World leaders meet in London to tackle the Ebola outbreak in west Africa which has so far claimed at least 3,000 lives.
More than 160 staff will work in a UK-funded facility in Sierra Leone which is due to open in October.
UK trials of a vaccine for the Ebola virus began today - but some experts complain that the response has been a long time coming.
