West Nile virus activity in United States blood donors and optimizing detection strategies: 2014-2018.

CONCLUSION: WNV NAT's utility is between June-December; however, abandoning testing outside of this time may increase risk. While in-process testing identified approximately one ID-NAT-only detectable (antibody-negative) donation per year, reducing the geographic triggered area decreased its effectiveness.
