The charity Save the Children has said "no stone will be left unturned" in its investigation into how a British nurse working at an Ebola treatment centre contracted the disease.
Pauline Cafferkey, from South Lanarkshire, had been working with the charity in Kerrytown, Sierra Leone. She is now critically ill in a north London hospital.
Luca Rolla is the director the Italian-run NGO Emergency. He worked with Pauline Cafferkey during her time in Sierra Leone and said she was "very committed" to her work.
