Hi Reddit, I am Sara Carazo, a medical doctor working for a long time with MSF (Médecins Sans Frontières). In 2005 I participated to the MSF response to a Marburg epidemic in Angola and in December 2014-January 2015 I was the MSF medical referent person for the Ebola clinical trial testing favipiravir in Gueckédou, Guinea. Since 2014 I am doing a PhD in Epidemiology at Laval University, Québec. My current research topic is on measles vaccination. My colleagues and I recently published in PLOS NTDS the article: Challenges in preparing and implementing a clinical trial at field level in an Ebola emergency: A case study in Guinea, West Africa. It is a viewpoint where we critically review all the challenges that we encountered to implement a clinical trial in the context of an uncontrolled Ebola virus epidemic and a vulnerable resource-poor setting of rural Guinea. I will be answering you questions at 1pm ET – Ask Me Anything!
