And in Florida, the virus seems to have gone into hiding. Health officials haven't investigated a new Zika case for more than 45 days in Miami-Dade County. (Doucleff, 6/12)

Florida researchers have developed a new device for detecting the Zika virus quickly and cheaply — although it might take years for it to come to market. Called the “Diagnoskeeter,” the portable, low-cost testing kit processes samples in 30 minutes and is “meant to [test for] all the families of the Zika virus,” said co-creator Ozlem Yaren, of the Foundation for Applied Molecular Evolution in Alachua.

The pesticide widely used to fight Zika-carrying mosquitoes in Florida and across the nation has been linked to deficits in motor functions in Chinese babies, according to a new study. The study, whose authors say it is the first to examine real-world exposure to naled outside workplace accidents or lab experiments, used cord blood from 237 mothers who gave birth to healthy babies at a hospital in southeast China between 2008 and 2011.
