An analysis of 85 Ebola virus sequences collected in Guinea from July to November 2014 provides insight into the evolution of the Ebola virus responsible for the epidemic in West Africa; the results show sustained transmission of three co-circulating lineages, each defined by multiple mutations.
An epidemic of Ebola virus disease of unprecedented size continues in parts of west Africa. For the first time, large urban centres such as Conakry, the capital of Guinea, are affected. We did an observational study of patients with Ebola virus disease in three regions of Guinea, including Conakry, aiming to map the routes of transmission and assess the effect of interventions.
