Doctors Without Borders/Médecins Sans Frontières (MSF) is rapidly putting together an Ebola team in Guinea to support the Ministry of Health’s Ebola response. We know from past experience that the speed of the response is important, both in order to contain transmission and to provide treatment for people who have caught the disease. We also know that community engagement is vital. We will try to get the right balance between responding quickly and taking steps to make sure the community is a willing and active participant in both prevention and response. Alongside treatment for Ebola, contact tracing and other community-based activities will be absolutely vital.
