At the height of the Ebola crisis, Scottish nurse Pauline Cafferkey volunteered to travel to Sierra Leone to help the afflicted and dying. When she returned home, her own crisis began - she had contracted the virus and in December 2014 became critically ill. In conversation with Julie Etchingham, she reveals how she has since suffered further complications - including contracting the virus a second time. She also talks about her current health and her hopes for the future, while her relatives relive their moments of fear.
