British Ebola survivor Will Pooley is returning to Sierra Leone where he contracted the virus, despite being told he may not be immune to it. Being a nurse Mr Pooley said that returning to help the crisis in West Africa was the 'right thing to do'. No one has ever been recorded catching Ebola twice and it is thought Mr Pooley will have at least short term immunity against this strain of the disease but this has never been tested. He has said he will act as if he is not immune and take the same precautions as other British staff in Freetown, the capital. Mr Pooley is flying out to Sierra Leone on Sunday evening and will join a team from the King's Health Partners, a coalition of three NHS hospital trusts in London. ‘I chose to go before and it was the right thing to do then and it’s still the right thing to do now,’ he said.
