Prevention of Zika Virus

Donated blood and blood components in the US

FDA advises testing for Zika virus in all donated blood and blood components in the US. As a further safety measure against the emerging Zika virus outbreak, today, August 26, 2016 the FDA issued a revised guidance recommending universal testing of donated Whole Blood and blood components for Zika virus in the United States and its territories. 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 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.
