Phylogeny

Time-scale phylogeny of sequenced Bundibugyo viral genomes, with tips coloured by health zone where sample collection took place. Node bars indicate the 95% HPD of the inferred dates.

Effective population size

Estimated effective population size (Ne) of the outbreak through time (up to the latest sample in the phylogeny). A rising curve indicates a growing epidemic; a plateau or decline indicates slowing transmission. SkyGrid is a flexible non-parametric estimate, Exp assumes an exponential-growth model. Shaded regions represent the 95% credible intervals.
