The Food and Drug Administration on Friday took steps to safeguard the nation’s blood supply from the Zika virus, calling for all blood banks to screen donations for the infection even in states where the virus is not circulating.
The recommendations are an acknowledgment that sexual transmission may facilitate the spread of Zika even in areas where mosquitoes carrying the virus are not present. Officials also want to prepare for the possibility that clusters of local infection will continue to pop up in parts of the United States for years to come.
