Genomic epidemiology reveals multiple introductions of Zika virus into the United States
Nathan D. Grubaugh, Jason T. Ladner, Moritz U. G. Kraemer, Gytis Dudas, Amanda L. Tan
+ et al.
Genome sequencing of Zika virus samples from infected patients and Aedes aegypti mosquitoes in Florida shows that the virus was probably introduced into the United States on multiple occasions, and that the Caribbean is the most likely source.

Establishment and cryptic transmission of Zika virus in Brazil and the Americas
R. Faria, J. Quick, I.M. Claro, J. Thézé, J. G. de Jesus
+ et al.
Virus genomes reveal the establishment of Zika virus in Brazil and the Americas, and provide an appropriate timeframe for baseline (pre-Zika) microcephaly in different regions.
 
Zika virus evolution and spread in the Americas
Hayden C. Metsky, Christian B. Matranga, Shirlee Wohl, Stephen F. Schaffner, Catherine A. Freije+ et al.
One hundred and ten Zika virus genomes from ten countries and territories involved in the Zika virus epidemic reveal rapid expansion of the epidemic within Brazil and multiple introductions to other regions.
