West Nile virus in 2006 and 2007: the Canadian Blood Services' experience

BACKGROUND: The Canadian blood supply has been screened for West Nile virus (WNV) since 2003. A strategy for targeted individual‐donation nucleic acid testing (ID‐NAT) was implemented in 2004 to identify potentially infectious donations that may be missed by minipool (MP) testing. In 2007, Canada experienced a larger epidemic than in previous years providing an opportunity to evaluate the ID‐NAT triggering algorithm in higher‐risk areas.
