A Miami Beach official stated that there has been no confirmation at this point that mosquitoes have spread the Zika virus in the city. In a statement emailed late Thursday, City Manager Jimmy Morales said Florida's Department of Health is investigating Zika cases in Miami Beach, but none have been confirmed to have originated there.
Morales said the city has been "proactively focused on the elimination of potential breeding sites for months," and is working with Miami-Dade County on mosquito control efforts such as targeted pesticide spraying and cleaning up areas where the insects could breed
In a separate statement Thursday, Florida health officials said they believe active Zika transmissions remain limited to a previously identified zone encompassing Miami's Wynwood neighborhood. However, the department also is investigating more than six other infections outside that area.
