Figure 3. Demographic reconstruction based on the nested coalescent model.

Figure 3

The colour scheme is consistent with that of the phylogeographic analyses in Figs. 1 and 2: the constant-logistic population size estimates (the ‘effective number of infections’, Ne, multiplied by the mean viral generation time, τ) through time are depicted in a black-yellow color range (following the African and Caribbean locations in the phylogeographic analyses) while the logistic population size estimates for the nested US clade are shown in blue (as for the US/NY location in the phylogeographic analyses).
