  1. Dead Bird Reporting and Testing “Hot Topic” Part I: Procedures

  2. Dead Bird Reporting • Will continue throughout the active surveillance period (May 1-Nov 30) • Use the dead bird log to keep track of all dead birds reported in the county • At the end of each week (Friday) compile the dead bird reports and fax the dead reporting form to IDEP (304-558-6335) • Report dead birds by the categories “crow” and “other” • Report dead birds found by zip code region (use the location zip code where the dead bird was found, not the PO box zip code of the caller)

  3. 2003 Bird Testing • ALL SPECIES of dead birds with no obvious signs of trauma • Fresh specimens, less than 24 hours old, without signs of decay • If the carcass is soft and mushy, has an obvious odor, has skin discoloration, feathers or skin that rubs off easily, and has ants or maggots, it is too decomposed for testing

  4. 2003 Dead Bird Testing Cont. • Submit dead birds to SCWDS using the submission form. • Obtain latitude and longitude information on each bird submitted. • Dead bird testing will continue within a single county until that county identifies a positive bird. Then, dead bird testing will stop within that county for 2003. However, dead bird reports should continue to be taken and reported on a weekly basis.

  5. Handling Dead Birds • Take a cooler containing ice with you • Use gloves when handling the bird • If picking up more than one bird, place each bird within a separate plastic bag inside the cooler

  6. Clusters of Dead Birds • Report clusters of dead birds to local DNR • Select two birds from the cluster to submit for West Nile testing

  7. Sending the Bird for Testing • Call IDEP (304-558-5358) to get the State ID • Send birds for testing using an overnight carrier (USPS or Fed-Ex) • Send birds ASAP, but do not send birds on Friday, Saturday or Sunday. • If you need to hold the bird overnight or over the weekend, refrigerate (DO NOT freeze) the bird

  8. Packaging Dead Birds • Double-bag the bird in two sealed bags (if sending in more than one bird, place each bird in separate bags) • Use the insulated shipping container provided by the State Health Department • Line the container with a large plastic bag

  9. Packaging Birds Cont. • Place double-bagged birds inside the large bag with enough blue ice packs (not wet ice) to keep the birds cold • Stuff newspaper in the spaces between the sides of the container and the outer plastic bag • Tape the box shut with packaging tape • Send overnight to SCWDS

  10. Paperwork and labels • Submission form (State ID, person/agency submitting, date collected, location with GIS reading) • Return address label • Biohazard label • Un 3373 label • Shipping label needs to say: DIAGNOSTIC SPECIMENS – WILDLIFE

  11. Now, it’s your turn…

  12. Dead Bird Reporting and Testing “Hot Topic” Part II: Surveillance

  13. Purpose • Determine geographic distribution • Identify focus areas of transmission • Target areas for mosquito testing • Predict where human cases may occur • Alert the public and providers about the risk of West Nile infection

  14. Why are we continuing to test dead birds!!!????? • Only have one year of experience with active West Nile surveillance • Dramatic changes in 2003 • We don’t know where West Virginia’s “hot spots” are • West Nile positive birds along with dead bird reporting can help to determine areas of increased risk • Need starting points for mosquito testing

  15. Why are some states focusing on crows? • Crows, other corvids, and raptor species are more likely to die from West Nile • 35% of Crows submitted in West Virginia were positive for West Nile • West Virginia dead bird reporting broken into crows and other • Will crows continue to be the best indicators????

  16. What is West Virginia doing with dead bird surveillance? • GIS coordinate plot of all positive birds • Zip Code region dead bird densities • Attempting to identify areas of increased West Nile risk • Identify areas where positive mosquitoes may be found

  17. West Virginia Population Density

  18. What should counties do? • Keep track of the locations of birds submitted for testing • Identify areas with high dead bird densities • Use dead bird surveillance to educate the public • Inform providers and the public of West Nile positive birds and areas with high dead bird densities • Sample mosquitoes within these areas • Determine if more efforts need to be put in to larvaciding and breeding site reduction in specific areas
