Its important to stay aware of circulating diseases while traveling, including vector-borne diseases. Some vector-borne diseases are more common during travel such as Zika, Malaria, and Yellow Fever. The Traveler’s Health website will keep you up to date on travel-related alerts and provides resources for staying healthy before, during, and after your trip.

Vector-borne Disease Data Dashboard

This dashboard uses interactive data visualizations to display vector-borne disease case data (counts and incidence rates), emergency department visits for tick-related illness, and vector-borne pathogen (germ) data in mosquitoes and ticks.

Vector-borne Disease Surveillance Reports

The Department conducts routine testing of mosquito pools and other sources of vector-borne illness. The results are published weekly during the annual peak period for vector-borne illnesses.

Fight the Bite, NJ!

Mosquitoes and ticks that spread germs (pathogens) are called vectors. A person who gets bitten by a vector and gets sick could have a vector-borne disease (VBD). Infected mosquitoes and ticks transmit many types of vector-borne diseases, some of which are acquired locally in New Jersey and others that occur among returning travelers. The best defense against VBDs is to take steps to avoid being bitten by mosquitoes and ticks. 

The Communicable Disease Service has staff dedicated to the monitoring, control and prevention of vector-borne diseases.

Specific activities performed by vector-borne illness staff include:

  • Surveillance of vector-borne diseases
  • Identifying risk factors
  • Monitoring geographic trends
  • Providing technical assistance and training
  • Educating the public and healthcare partners

Travel-related Tick and Mosquito-borne Diseases

Some vector-borne diseases that do not occur in New Jersey but may be identified in travelers returning from other states or countries where these diseases may occur:

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.
