Nearly a year since the Zika virus outbreak arrived in Miami, scientists say they`ve learned new details about how the mosquito-born virus emerged and spread throughout the Americas. Researchers sequenced nearly 200 Zika virus genomes to see how the virus mutated and traveled over time. These genetic blueprints shed new light on a poorly understood epidemic that`s affected thousands of people in recent years. `We used [genomes] to investigate the timing and path of how Zika spread in a way that had not yet been possible, until now,` Browyn Macinnis, an associate director at the Broad Institute of MIT and Harvard, said this week on a press call....
