Insights into intercontinental spread of Zika virus.

ABSTRACT: The epidemic of Zika virus (ZIKV) infection in South America has led to World Health Organization's declaration of a Public Health Emergency of International Concern. To further inform effective public health policy, an understanding of ZIKV's transmission mechanisms is crucial. To characterize the intercontinental transmission of ZIKV, we compiled and analyzed more than 250 gene sequences together with their sequence-related geographic and temporal information, sampled across 27 countries spanning from 1947 to 2016. After filtering and selecting appropriate sequences, extensive phylogenetic analyses were performed. Although phylogeographic reconstruction supported the transmission route of the virus in Africa, South-eastern Asia, Oceania and Latin America, we discovered that the Eastern A
