Dead birds

When a dead bird is sighted, the information about that bird is recorded. If the bird meets the criteria for testing, it is collected and sent for testing. Samples are from each bird are tested for WNV. This table records the surveillance effort in Pennsylvania by whole birds,rather than partial tissues from the birds.

Mosquitoes

All mosquitoes collected in one effort create a sample of mosquitoes. This sample is sent to the lab for identification. A sample can include either larval or adult mosquitoes. Only adult mosquitoes are tested for WNV. All mosquitoes are identified, and adults are divided into subsamples by species for testing. This table records the surveillance effort in Pennsylvania by samples, rather than subsamples of mosquitoes.

Veterinary Samples

Diagnostic blood samples from equine and other animals submitted by veterinarians across the state will be tested for WNV. Please note that since it is impossible to differentiate between naturally infected horses and vaccinated horses, it is important that the vaccination history of any horse that is being tested be provided to the laboratory. A reporting form is available for submission with samples from the Pennsylvania Veterinary Laboratory.
