Figure 1. Maximum likelihood phylogenetic tree inferred for concatenated of sequences from Envelope and NS5 genes of Zika virus.

Consensus tree summarized after 1000 non-parametric bootstrap replicates, with support values greater than 60% shown in the nodes. The cluster the Ugandan MR766 prototype strain was highlighted by the yellow sector and the Nigerian cluster was highlighted by the green sector. The strains from Senegal and Côte d'Ivoire are shown in green and orange, respectively. The tree has been rooted with the Spondweni lineage isolated in South Africa was used as outgroup to root the tree.
