Dr Roger Alcock is a consultant in emergency and pediatric medicine. He's one of the many medics from across Britain's National Health Service who are joining the UK's fight against Ebola in Sierra Leone.

He works at the Forth Valley Royal Hospital, Larbert, in Scotland - but this is not the first time he's volunteered to help abroad:

"I've previously worked at a Scottish government initiative in Malawi, helping to develop emergency medicine at the hospital in Blantyre."

Like all the medics heading to Sierra Leone, he is committed to his profession and the cause:

"My father was a doctor and did his utmost to encourage me to consider other options, but the bottom line is that I'm quite a people-person and it's a complete privilege to get to look after them."
