Dead Birds

Testing criteria for dead birds in Nebraska are only birds that have been dead less than 24 hours; all species of birds (fledgling age and older) will be accepted for testing; and birds will only be accepted from counties with less than five positive dead birds. Specific date and address information (including county and zip code) is requested for birds that are submitted for testing.

 

Mosquitoes

Adult mosquitoes are collected every two weeks from routine surveillance sites around the state. Supplemental mosquito trapping may be performed by Health and Human Services System personnel as needed. A mosquito sample is all mosquitoes from one CDC-miniature light trap ran for one night at a single location. Samples are sorted and female (bloodfeeding) mosquitoes are identified to species and counted. Mosquitoes in the genus Culex are pooled in vials containing up to 50 mosquitoes of the same species and are submitted for testing for West Nile virus.
