Miami Beach official: No confirmation of Zika spreading

A Miami Beach official says there's been no confirmation that mosquitoes have spread the Zika virus in the tourism-dependent 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.

Morales said the city has been "proactively focused on the elimination of potential breeding sites for months." He said the city 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 over six other infections outside that area.
