Keeping Blood Transfusion Safe From West Nile Virus: American Red Cross Experience, 2003 to 2012

West Nile virus (WNV) appeared for the first time in the United States in 1999 and rapidly spread across the Western hemisphere within a few years causing hundreds of thousands of human infections and significant disease. In 2002, it was found to be transmissible by blood transfusion, and within less than a year, nucleic acid testing for WNV RNA was in place for all US donations. The American Red Cross (ARC) collects approximately 40% of blood donations in the United States and closely monitors the results of such testing and evaluates donors found to be reactive.
