Blood & Tissue Safety: Geographic Areas with Zika Virus Transmission Risk

Zika virus information for blood collection and tissue recovery organizations

CDC is working with state health departments and blood and tissue recovery organizations to help ensure the safety of our blood and tissue supply and reduce the risk of Zika virus transmission through blood transfusion 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.

Special Notice – March 13, 2017

Potential Increased Risk to Blood and Tissue Safety

CDC has identified the potential for increased risk to blood and tissue safety in Miami-Dade County starting on June 15, 2016. The potential risk in Miami-Dade County did not meet the threshold for designation as an area of active transmission until July 29, 2016. 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. The complete list of current and past areas of active transmission is provided below.

Areas of Active Zika Virus Transmission Risk 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 based on the designation of Zika cautionary (yellow) areas. These defined areas of risk can be different from areas for which CDC has issued travel guidance. For the purposes of blood and tissue safety intervention, areas of active Zika virus transmission will be defined at the county-level.

The following are areas of active Zika virus transmission risk in the continental United States for the purposes of blood and tissue safety intervention:

  • Miami-Dade County, Florida – As of July 29, 2016
  • Cameron County, Texas – As of December 9, 2016

The following are previously listed areas of active Zika virus transmission risk  in the continental United States for the purposes of blood and tissue safety intervention:

  • Palm Beach County, Florida – From August 24, 2016 – November 2, 2016*
