2005
West Nile Virus
Viremic Blood Donor
Activity in the United States
A
total of 417 presumptively viremic blood donors (PVD) have been reported
to CDC's ArboNET surveillance program through state and local health
departments for 2005. A PVD is a person whose blood tested positive in preliminary tests when screened for the presence of West Nile virus. PVDs are followed up by the blood agency to verify their
infection with additional tests. Some PVDs do go on to develop symptoms
after donation, at which point they would be included in the count
of human disease cases by their state. |
