Ebola virus genome provides clues to repeated disease ‘flare-ups’ in Western Africa

Ebola virus samples taken from Liberian patients in June 2015 are genetically similar to other Ebola virus sequences from Western Africa, according to new research. The study sheds light on several aspects of the ‘flare-ups’ that have occurred in Liberia since the country was declared free of the disease. Among the findings: These cases were not a re-introduction from a neighboring country, but came from a persistently infected source within Liberia.
