CDC has also identified that since June 15, 2016, there has been a potential increased risk to blood and tissue safety in Broward and Palm Beach counties because of local travel of residents of these counties to areas of active transmission in Florida.

Areas At Risk For Locally Acquired Vector-borne Zika Cases
Zika virus information for the blood and tissue collection community
CDC is working with state health departments and blood and tissue collection organizations to help ensure the safety of our blood and tissue supply and reduce the risk of Zika virus transmission through blood transfusions and tissue transplants. Zika virus disease is a nationally notifiable condition. Cases are reported to CDC by state and local health departments using standard case definitions.
Areas of Active Transmission in the United States
To protect the US blood and tissue supply, CDC in collaboration with the US Food and Drug Administration (FDA) defines areas of active Zika virus transmission as having two or more locally acquired cases of Zika virus infection within 45 days. These defined areas of risk can be different from areas for which CDC has issued travel guidance because of concerns about potential risk for blood and tissue safety.
The following are areas of active transmission of Zika virus in the continental United States for the purpose of blood and tissue safety intervention:
