As a further safety measure against the emerging Zika virus outbreak, today the U.S. Food and Drug Administration issued a revised guidance recommending universal testing of donated Whole Blood and blood components for Zika virus in the U.S. and its territories.

“There is still much uncertainty regarding the nature and extent of Zika virus transmission,” said Peter Marks, M.D., Ph.D., director of the FDA’s Center for Biologics Evaluation and Research. “At this time, the recommendation for testing the entire blood supply will help ensure that safe blood is available for all individuals who might need transfusion.”

The FDA first issued guidance on Feb. 16 recommending that only areas with active Zika virus transmission screen donated Whole Blood and blood components for Zika virus, use pathogen-reduction devices, or halt blood collection and obtain Whole Blood and blood components from areas of the U.S. without active virus transmission. All areas with active transmission in the U.S. are currently in compliance with this guidance. The revised guidance announced today recommends that all states and U.S. territories screen individual units of donated Whole Blood and blood components with a blood screening test authorized for use by the FDA under an investigational new drug (IND) application, or a licensed test when available. Alternatively, an FDA-approved pathogen-reduction device may be used for plasma and certain platelet products.

The FDA is updating its guidance after careful consideration of all available scientific evidence, consultation with other public health agencies, and taking into consideration the potential serious health consequences of Zika virus infection to pregnant women and children born to women exposed to Zika virus during pregnancy. Testing of donated blood is already underway in Florida and Puerto Rico, as well as in other areas, and it has shown to be beneficial in identifying donations infected with Zika virus. Expanded testing will continue to reduce the risk for transmission of Zika virus through the U.S. blood supply and will be in effect until the risk of transfusion transmission of Zika virus is reduced.

“As new scientific and epidemiological information regarding Zika virus has become available, it’s clear that additional precautionary measures are necessary,” said Luciana Borio, M.D., the FDA’s acting chief scientist. “We are issuing revised guidance for immediate implementation in order to help maintain the safety of the U.S. blood supply.”

In addition to protecting the nation’s blood supply, the FDA works to protect the safety of our nation’s supply of human cells, tissues, and cellular and tissue-based products; supports the development and availability of diagnostic tests that may be useful for identifying the presence of or prior exposure to the Zika virus; works with commercial and government developers to advance the development of investigational vaccines and therapeutics; and monitors for fraudulent products and false product claims related the Zika virus.
