The World Health Organization reports that over 60 countries and territories suffer from continuing transmission of Zika, while the Centers for Disease Control (CDC) says that more than 40,000 people in the U.S. and its territories have been infected, including at least 4,750 pregnant women. With the growing danger of this infectious disease, and the impeding threat of neurological problems and brain damage it poses to developing babies, fast and accessible methods to screen for Zika and control its spread are urgently needed.
