This is an analysis of Ebola virus genome sequences being produced in the field by teams in Sierra Leone and Guinea over the last few months as the epidemic continues in these countries. A total of 145 sequences from Sierra Leone have been produced a consortium from the Wellcome Trust Sanger Centre, the University of Cambridge and Public Health England. A total of 51 sequences from Guinea have been produced by the EMLab/EVIDENT consortium in collaboration with University of Birmingham.
Figure 1 | Time-resolved phylogenetic tree inferred from an alignment of 985 EBOV genomes. Tips coloured in red are from the previous release of WTSI/UoC/PHE genomes, while those in orange are the novel WTSI/UoC/PHE sequences from Sierra Leone. Tips coloured in blue are the novel EMLab-RT sequences from Guinea. Lineages containing the newly-sequenced isolates are highlighted with coloured boxes and labelled A-H for lineages derived from the SL3 lineage, or GUI-1 for the divergent Guinean lineage. Branches are coloured by inferred geographical location: blue for Sierra Leone, green for Guinea, and orange for Liberia.
