Spread of Asian/American lineage of Zika virus

Phylogeography of Zika virus from 1997 - Sep 2017

This analysis was produced using data collected and generated as part of a large collaborative study to identify how Zika virus spread to Florida, USA during the 2016-16 Zika virus pandemic. For more details, please see Grubaugh et al. 2017. The video shows the spatio-temporal diffusion of viral lineages between 1997 and 2017 that was generated by reconstructing the ancestral phylogeny of Zika virus.

All genomic sequences used in the analysis are publicly available on GenBank. Tree was generated using BEAST v1.8.4 under a SRD06 nucleotide substitution model and a relaxed molecular clock along with a Bayesian Skyline model. The BEAST XML file is available in data. The phylogeographic diffusion process was realised using a discrete state asymmetric CTMC.
