Working as a pharmacist in some of the worst conflict zones in the world has given Petra Straight a new perspective on risk.
She was part of the response to the Ebola outbreak in Sierra Leone, and now works for Save The Children’s Emergency Health Unit.
It’s a role that has taken Petra all over the world - helping vaccinate against yellow fever in the Congo, and working within a reproductive health programme in Mozambique.
Until just recently, Petra was in Cox's Bazar in Bangladesh, helping set up a Covid-19 treatment centre at the refugee camp there for Rohingya fleeing persecution in Myanmar.
She's now in self-isolation in London.
