Four Zika virus cases under investigation in Florida may have been transmitted by local mosquitoes
The Florida Department of Health is investigating four cases of Zika virus that may not be related to travel and instead have been possibly spread by local mosquitoes, the department said Wednesday. Of the four cases under investigation, two were newly announced on Wednesday and two had been previously reported and are already under investigation. While a number of cases of Zika virus have been reported in the U.S., local mosquito transmission, though expected, hasn't yet been confirmed. To determine the number of people affected, the investigation involves door-to-door interviews in the areas the affected people frequently visited and urine and/or blood sample testing of residents and visitors, the department said. A department spokesperson said there is no timeline for the release of the investigation's results.
