Additional Information & Advisories

  • The risk of WNV infection has increased with the arrival of spring and people should take steps now to eliminate mosquito-breeding areas around their homes and protect themselves and their families from infection.

  • Among the personal precautions residents can take now are such measures as eliminating standing water on their own property (such as clearing clogged gutters, draining flower pots, recycling old car tires, etc.), and repairing window and door screens. In the spring, summer, and fall residents can spray insect repellent on their clothing and exposed skin in accordance with labeling directions, wear long sleeved shirts and pants when outdoors, or curb outdoor activities at dawn, dusk and during the evening.

  • The West Nile virus, an arboviral disease, is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. WNV is not directly transmitted from birds to humans or from person to person. WNV infection generally causes no symptoms or just mild, flu-like symptoms; however, the elderly are at higher risk of more severe disease.

  • Since 1999, lab testing has confirmed WNV infection in 18 New Jersey residents, with two resulting fatalities. The virus has also been detected in mosquitoes, horses, or crows and other birds in every county in New Jersey.

  • New Jersey's WNV surveillance, control and prevention activities involve the coordinated efforts of a number of federal, state and local agencies. These include the New Jersey Departments of Health and Senior Services, Environmental Protection, and Agriculture, the CDC, the State Mosquito Control Commission, the Rutgers Mosquito Research and Control Unit, and local health and mosquito control agencies.
