Phylogenetic tree of Zika virus (ZIKV). The complete genome sequences of ZIKV isolates were obtained from GenBank. The phylogenetic tree was constructed by maximum likelihood model with 1000 bootstrap replicates. The identification of the strains is in the format of accession number/host/country of isolation/year of isolation. ZIKV strains were grouped into two lineage, namely, Asian lineage and African lineage based on their geographical distribution.
