2007 West Nile Virus Biovigilance Network

The West Nile Virus (WNV) Biovigilance Network collates data on donors (blood, tissue and hematopoietic progenitor cells) with suspected WNV infection in the United States and Canada. Data for the calendar year 2007 were collected from donor screening performed by nucleic acid testing (NAT). The data were reported to the AABB site by facilities responsible for testing virtually all donations in the United States and Canada. The reports provided here illustrate the geographic and temporal distribution of WNV infection as reflected by presumed viremic donors (PVDs) during the 2007 peak season.
 
This section includes a map showing locations where these PVDs have been identified; a bar graph identifying total PVDs by week collected; and a password-protected section for reviewing reports of WNV activity.

2007 U.S./Canada Map: Suspected Cases by Postal Code (updated 1/24/08)

This map shows presumed viremic donations (PVDs) by residential postal code of the donor in the United States and Canada. To be defined as a PVD, the sample must meet one of the following criteria: 1) a reactive sample that is repeatable by ID NAT, i.e., repeatable NAT reactivity using the same screening test, analogous to repeat reactivity in serology; or 2) reactivity in the Procleix assay that has a signal-to-cutoff ratio exceeding or equal to 17. PVDs are reported by facilities as they occur based on test results.

2007 WNV Presumed Viremic Donations by Week (updated 1/24/08)

This bar graph identifies the total number of presumed viremic donations (PVDs) by week of donation as identified through NAT. PVDs are defined as: 1) a reactive sample that is repeatable by ID NAT, i.e., repeatable NAT reactivity using the same screening test, analogous to repeat reactivity in serology; or 2) reactivity in the Procleix assay that has a signal-to-cutoff ratio exceeding or equal to 17. PVDs are reported by facilities as they occur based on the test results.
