Leading US doctors urge funding for Zika fight

The top two U.S. doctors fighting the Zika epidemic sounded even louder alarm bells about the deadly virus on Thursday, insisting it poses an urgent threat and begging Congress to free up money to pay for the fight. Efforts to fight other diseases, from HIV to dengue, are on hold while money is cobbled together for the anti-Zika push, the directors of the Centers for Disease Control and Prevention and the National Institute of Allergy and Infectious Diseases (NIAID) said. CDC director Dr. Thomas Frieden visited Puerto Rico, the U.S. territory that he calls "ground zero" for Zika in the U.S.. He didn't have much good news to share from his visit.
