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

- 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
- 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.
