By Julie Steenhuysen CHICAGO (Reuters) – Florida officials on Tuesday announced the first case of Zika transmitted by mosquitoes in Pinellas County, located some 265 miles (425 km) from Miami, where the first locally transmitted U.S. cases were reported. Steve Huard, acting spokesman for Florida Department of Health in Pinellas County, said the case involves a woman without a significant travel history, indicating the virus was contracted locally. “We don’t know where it originated, and we are doing appropriate testing and medical surveillance.” Florida Governor Rick Scott said the state department of health has begun door-to-door outreach in Pinellas County, testing individuals to find other cases.
