Laboratory Testing and Guidance

There are several emerging/reemerging or very rare arboviral diseases that are transmitted by mosquitoes or ticks that may impact NJ residents. Commercial testing may not be widely available, but specialized testing at public health laboratories can be provided for these diseases. Clinicians who would like to request arboviral disease testing should complete the Arboviral Testing Request worksheet and send via encrypted email to Arboviral testing can be requested for patients who are hospitalized with neuroinvasive disease (e.g., encephalitis, meningitis, acute flaccid paralysis) of unknown etiology or, for patients presenting with a febrile illness of unknown etiology if an arboviral disease is suspected.

Ill or Dead Bird Reports

NJDOH no longer tests birds for West Nile Virus, but if you find an ill or dead bird on your property, you should report it to your county mosquito control agency who will use that information as a part of  West Nile Virus mosquito surveillance efforts and the NJDEP Division of Fish and Wildlife.

For reports of sick or dead domestic poultry, including gamebirds, backyard poultry and exhibition poultry, please contact New Jersey Department of Agriculture immediately at (609) 671-6400.
