This lab is ground zero in the U.S. fight against Zika

 As the Zika virus speeds through the hemisphere, a cluster of one-story buildings set in the shade of banyan and mango trees has become the epicenter of the U.S. fight against the pathogen.

Behind an unmarked gated entrance in this working-class neighborhood of San Juan, scientists from the Centers for Disease Control and Prevention have only one focus: to stop Zika's spread. About 100 virologists, biologists, entomologists and more are working here, including dozens brought from CDC sites in Colorado and Georgia. They're racing to develop tests for faster and more accurate diagnosis of infection and killing Aedes aegyptimosquitoes by the hundreds to determine what chemicals are most effective.
