A birds eye view: using geographic analysis to evaluate the representativeness of corvid indicators for West Nile virus surveillance

摘要

BackgroundThe objective of this evaluation was to determine whether reports of dead corvid sightings and submissions of dead corvids for West Nile virus testing were representative of true corvid mortality in British Columbia in 2004, a year with no West Nile virus activity, in order to ensure the system was accurately describing corvid mortality rather than reflecting regional differences in surveillance methods.
