In a large collaboration between Kenema Government Hospital, Harvard University, Broad Institute, Tulane University, Edinburgh University, the Centers for Disease Control, United States Army Medical Research Institute of Infectious Diseases, and others, the Viral Hemorrhagic Fever Consortium has published a paper in Cell detailing the epidemiology, transmission, and evolution of Ebola virus over seven months in Sierra Leone. The new study sequenced 232 new Ebola virus genomes, which were all released on NCBI and virological.org prior to publication. Adding important new insights into the paper published by the Consortium in Science last year, this study shows that the outbreak is still sustained by a continued human-to-human transmission chain.
