TL;DR: It is revealed that this large epidemic was a heterogeneous and spatially dissociated collection of transmission clusters of varying size, duration and connectivity, which will help to inform interventions in future epidemics.

TL;DR: The Magazine Wharf area, Freetown, Sierra Leone was a focus of ongoing Ebola virus transmission from late June 2015 and viral genomes linked to this area contain a series of 13 T to C substitutions in a 150 base pair intergenic region downstream of viral protein 40 open reading frame, similar to the Ebolavirus/H.sapiens-wt/SLE/2014/Makona-J0169 strain.

TL;DR: It is found that despite a strong attenuation of international dispersal after border closures, localized cross-border transmission beforehand had already set the seeds for an international epidemic, rendering these measures relatively ineffective in curbing the epidemic.
