Gov. Rick Scott says officials have identified a second area of Zika transmission on the U.S. mainland.
Scott told reporters Friday that five Zika infections have been linked to an area that encompasses most of tourist-friendly South Beach.
Florida Department of health spokeswoman Mara Gambineri says officials believe the cases were transmitted by mosquitos.
Another infection zone was previously identified in Miami’s Wynwood arts district.
Scott says two of the Miami Beach cases involved Miami-Dade County residents, and three involved tourists from New York, Texas and Taiwan. He did not say whether mosquito bites caused the infections.
Scott says the county has begun an aggressive mosquito eradication plan in Miami Beach.
