FDA to change guidelines to protect blood supply from Zika virus

The Food and Drug Administration is recommending U.S. blood banks refuse donations from people who have traveled to countries where the Zika virus is active in the prior four weeks.

It’s part of a set of guidelines meant to protect the blood supply from the mosquito-borne virus.

The agency is also recommending establishments turn away donors who may have had sexual contact with someone who has traveled to a Zika-affected country in the last three months.
