for the remainder. Blood and/or spinal fluid samples from these
individuals were tested for the presence of WNV
- These individuals
either had symptoms or signs that met the established WNV testing
criteria. · Human testing for WNV is being conducted at
the New Jersey Department of Health and Senior Services’ Public
Health and Environmental Laboratory in Trenton and at public
health labs in other states.
- To date 172 birds have been submitted for testing
by the Department of Health and Senior Services Public Health
and Environmental Laboratory. Of those tested, 39 birds found

of WNV. Positive crows have been found in Atlantic (14), Bergen
(1), Cape May (5), Essex (3), Gloucester (2), Mercer (1), Middlesex

Additional Information & Advisories
- The risk of WNV infection has increased with the arrival
of summer and people should take steps now to eliminate mosquito-breeding
areas around their homes and protect themselves and their families
- 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. WNV infection
generally causes no symptoms or just mild, flu-like symptoms;
however, the elderly are at higher risk of more severe disease.
- In New Jersey, a total of 76 people have been diagnosed with
between 1999 and 2003. Lab testing confirmed WNV infection in
these residents, with five resulting fatalities. WNV activity
(identified from avian, equine and/or mosquito surveillance)
has been detected in every county in New Jersey.
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.
