Fig. 4From: Genomic epidemiology supports multiple introductions and cryptic transmission of Zika virus in ColombiaPhylogeny of 28 clade 1 viruses. The inferred geographic migration history indicates movement from Brazil into Colombia, with subsequent migration into other countries in South America, Central America, and the Caribbean. The estimate of introduction timing and the 95% confidence interval are given for the most basal node of the cladeBack to article page
