The origin of emerging Zaire ebolavirus is investigated at each outbreak. To reliably do so a good understanding of the Zaire ebolavirus in its reservoir is needed. Therefore ebolavirus full genomes were used to investigate between-outbreak circulation dynamics. The results highlight the need to appropriately account for the limits of coalescent models when reconstructing between-outbreak evolutionary history. Contrary to what was expected the circulation dynamics of Ebola virus in its animal reservoir appeared highly uncertain.
