Food and drug body expands Zika screening to all US blood centres

The Food and Drug Administration wants all US blood centers to start screening for Zika, a major expansion intended to protect the nation’s blood supply from the mosquito-borne virus. Friday’s advisory means all US states and territories will need to begin testing blood donations for Zika. Previously, the FDA had limited the requirement to Puerto Rico and two Florida counties.

“There is still much uncertainty regarding the nature and extent of Zika virus transmission,” said Dr. Peter Marks, director of the FDA’s biologic products center, in an agency release. “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.”

Blood collection sites already test donations for HIV, hepatitis, West Nile virus and other blood-borne viruses.

FDA officials said Zika testing is already underway in Puerto Rico and parts of Florida, where “it has shown to be beneficial in identifying donations infected with Zika virus.”

The FDA has authorized use of two experimental blood-screening tests for Zika, one made by Roche and another from Hologic Inc. Several testing sites are already voluntarily using the technology, including blood centers in Texas.
