LA JOLLA, California — The Zika virus outbreak in the United States in 2016 was caused by multiple infected travelers arriving in South Florida, not by a single "patient zero," genomic research has revealed.
Reporting here at the 10th Future of Genomic Medicine Conference, Kristian Andersen, PhD, from Scripps Translational Science Institute in La Jolla, California, and his team identified four different "introductions" of the Zika virus during the outbreak using genomic sequencing by testing samples from 17 people.
Extrapolating this to the total number of infected people, "the number of introductions that caused the outbreak in Miami is quite substantial," maybe on the order of 30, he explained.
Genomic sequencing of the virus from mosquitos and patients also revealed that Caribbean travelers were the primary means of introduction.
