Animation of reconstructed movement of Ebola virus between the geographical districts of Guinea, Sierra Leone and Liberia over the course of 2014 and 2015. Moving line segments represent a single reconstructed movement (black segments are within a country, coloured segments represent inter-country movements). Individual districts are coloured with saturation proportional to the number of recorded cases each week. Green denotes Guinea, blue Sierra Leone and red Liberia.
The reconstruction is based on a time-scaled phylogenetic reconstruction using BEAST with a discrete phylogeographical model. 1561 genome sequences kindly provided by many labs and groups. Animation made using Python by @evogytis. Analysis and data is the work of many people.
The analysis is part of a paper in preparation. I will post more results here shortly.
