A
total of 224 presumptively viremic
blood donors (PVD) have
been reported to CDC's ArboNET surveillance program
through state and local health
departments.
A PVD is a person who was asymptomatic at the time of
donating blood (people with symptoms
are deferred from
donating) through a blood collection agency, but 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.
