Testing criteria for dead birds in Nebraska require only birds that have been dead less than 24 hours. We accept birds in the crow family (corvids), fledgling age and older, for testing. Birds will only be accepted from counties for testing until the local public health department finds a West Nile Virus-positive bird or mosquito in their jurisdiction. Please provide specific date and address information (including county and zip code) for birds you submit for testing.
We collect adult mosquitoes every two weeks from routine surveillance sites around the state. DHHS personnel may perform supplemental mosquito trapping as needed. A mosquito sample is all mosquitoes from one CDC-miniature light trap ran for one night at a single location. The first task is to sort the samples. Then, we identify female (blood feeding) mosquitoes to species and count them. We pool the mosquitoes in the genus
Culex in vials that contain up to 50 mosquitoes of the same species. The last step is to send them for testing for West Nile virus.
