Concurrent transmission of Zika virus during the 2023 dengue outbreak in Dhaka, Bangladesh
Fig 3
The maximum likelihood phylogenetic tree of 89 E gene coding sequences of ZIKV circulating worldwide.
The tree was constructed using the bestfit substitution model with an ultrafast bootstrap of 1000 replicates. The Bangladeshi (BD) strains are denoted by purple asteroids. All three BD ZIKV strains were closely related to each other and classified under the Asian sublineage. They formed a distinct node, grouping together with Cambodian and Chinese strains from 2019.
