Zika virus: FDA recommendstesting for all blood donated in U.S.
- By Alice de la Chapelle
The U.S. Food and Drug Administration recommends that all blood donated in the United States and its territories be tested for Zika virus, as it moves to prevent transmission of the virus through the blood supply. The current Zika outbreak was first detected in Brazil last year and has since spread across the Americas. In Brazil, Zika has been linked to more than 1,800 cases of microcephaly, and U.S. officials expect as many as 270 cases in Puerto Rico, where local transmission of the virus is widespread. Testing of donated blood is underway in Florida, Puerto Rico, as well as in other areas of the United States, and has been proven helpful in finding infected donations.
