RABIES INFORMATION
General Information
Rabies is a fatal disease caused
by a virus. It is transmitted through direct contact of infected
mammalian body fluids. The disease is usually spread when when an
infected animal bites another animal or person. However, rabies can
be spread when infected saliva, or other fluid, enters an open cut,
mouth or eyes. The virus enters the bloodstream and travels to the
nervous system where it replicates. The incubation period of rabies
can vary depending on the species of the animal and the location of
the infection site. It is common practice to quarantine a rabies
suspect animal for 10 days. If the animal develops signs of rabies or
dies within this period, brain tissue samples are sent to the New
Jersey State Rabies Laboratory in Trenton, New Jersey for testing.
The animal may have to be quarantined for a longer period depending
on the circumstances. It could take several days or months for
symptoms to appear. A positive diagnosis for rabies can be made only
by laboratory examination of brain and salivary tissues after the
death of the animal.
What are the
symptoms of Rabies?
Early in the disease, slight
temperament or behavioural changes may be observed. As the disease
progresses, the animal may become increasingly agitated or excitable,
and may try to eat unusual objects. The animal may develop trouble
swallowing and will drool excessively. Rabid animals are often
extremely aggressive. Seizures may indicate the end stage of the
disease. Other symptoms include: staggering, hind-end paralysis,
facial convulsions, attacking their own body parts and loss of fear
around humans.
Which animals
are affected by Rabies?
All mammals can be affected by
rabies, however, some are more susceptible than others. For example;
foxes, skunks, bats, and raccoons are more likely to infected than
squirrels, rabbits, opossums and domestic animals.
What are the
procedures if bitten by an animal?
Anyone who is bitten or scratched
by a wild or domestic animal should immediately seek medical
attention and report the incident to your local Police Department and
to your local Animal Control Officer. Rabies treatments are only
effective if started immediately following exposure. The same
procedure goes for pets that have been attacked by other animals even
if your pet has had rabies vaccinations.
Can Rabies be prevented?
Yearly vaccination of dogs and
cats is the best way to reduce human and pet exposure. A vaccinated
pet that encounters a rabid animal has a much better chance of being
treated than an unvaccinated pet. Control of stray animals can
decrease the spread of rabies. Contact with wildlife should be
avoided and do not keep wild animals as pets! Never attempt to remove
or re-locate wildlife without consulting a professional. Always
report unusual behaviour to the Animal Control Office.
Is Raccoon
Rabies different from other Rabies?
No. Raccoon rabies is the exact
same disease as the rabies that effects other animals. Raccoon rabies
is a strain of rabies that is spread mainly by raccoons. All other
animals can be infected with raccoon rabies. Since there is a large
raccoon population in this area, precautions and protective measures
are being taken to prevent the spread of this strain of the disease.
The Bottom
Line on Rabies...
The incidence of rabies has dramatically
declined since the 1980's. We have gone from several hundreds of
cases of rabies being reported each year to only a few. Public education
and preventative measures can go a long way in keeping this disease
under control. For more information please contact your local Animal
Control Office or Health Department or email us at animal@twp.stafford.nj.us.
WEST NILE INFORMATION
What is West
Nile virus encephalitis?
West Nile virus (WNV) encephalitis
is a mosquito-borne viral disease, which can cause an inflammation of
the brain. WNV is commonly found in Africa, West Asia, the Middle
East and Europe, and is closely related to St. Louis encephalitis
virus, which was found in New Jersey in 1964 and 1975. For the first
time in North America, WNV was confirmed in the New York metropolitan
area during the summer and fall of 1999. WNV successfully
over-wintered in the northeastern United States and was present in
humans, horses, birds, and mosquitoes in 2000 and 2001. Preparations
are being made to monitor for WNV activity again in 2002.
How do people
get West Nile virus encephalitis?
WNV is transmitted to people by
the bite of a mosquito that has become infectious after feeding on a
bird infected with the virus. Birds serve as the reservoir hosts of
WNV, and the principal vector in the transmission from one bird to
another is the northern house mosquito, Culex pipiens and other Culex
mosquitoes. WNV has also been found in several species of Aedes
mosquitoes, which could serve as bridge vectors by transmitting it to
humans or horses.
How many
cases of West Nile virus infection occurred in New Jersey in 2001?
Twelve residents of New Jersey,
out of a total of 110 which initially met WNV testing criteria, have
been confirmed positive for WNV to date.
What are the
symptoms of West Nile virus infection?
Most infections produce no
symptoms in people, or symptoms are mild or moderate. Symptoms may
include: fever, headache, and body aches, often with skin rash and
swollen lymph glands. More severe infections may be marked by
headache, high fever, neck stiffness, muscle weakness, stupor,
disorientation, convulsions, paralysis, coma, and, rarely, death.
What tests
does the New Jersey Department of Health and Senior Services (DHSS)
do to determine a human case of West Nile virus encephalitis?
To screen potential cases for WNV,
blood and cerebrospinal fluid samples are sent to the Public Health
and Environmental Laboratory (PHEL) for an Enzyme-Linked
Immunosorbent Assay (ELISA) test that detects antibodies IgG &
IgM in sera and IgM only in cerebrospinal fluid.
What is a
confirmatory test?
If the ELISA test is positive,
samples are then forwarded to the National Centers for Disease
Control and Prevention (CDC) for a plaque reduction neutralization
test (PRNT), which is the final confirmatory test for WNV in humans.
How is West
Nile encephalitis treated?
There is no specific therapy. In
more severe cases, intensive supportive therapy is indicated, i.e.,
hospitalization, intravenous (IV) fluids, airway management,
respiratory support (ventilator) if needed, prevention of secondary
infections (pneumonia, urinary tract, etc.), and good nursing care.
What is the
incubation period in humans?
Symptoms usually appear 5 to 15
days from the time a mosquito carrying WNV infects a person.
Where did the
people with West Nile virus encephalitis in New Jersey in 2001 become infected?
The patients resided in 6
different counties, but it is not possible to determine where each
patient was bitten by infectious mosquitoes. It is most important
that residents in all parts of the state take preventive measures to
reduce the risk of mosquito bites, as outlined in this Fact Sheet and
other educational materials.
Should
outdoor activities in August and September be cancelled when there is
evidence of West Nile virus activity?
There is no reason to change plans
for outdoor activities, but common sense should be taken to avoid
mosquito bites, particularly at dusk and early evening.
What
proportion of people die when infected with WNV?
Since the majority of infected
persons are asymptomatic, the fatality rate is less than 1%. However,
case fatality rates for hospitalized patients may range from 3% to
15%, and are highest in the elderly.
Can you get
WNV directly from crows or from other people?
There is no evidence that a person
can get the virus from handling live or dead infected birds. However,
avoid barehanded contact when handling any dead animal. WNV is NOT
transmitted from person-to-person. There is some evidence that
crow-to-crow transmission of WNV is possible without mosquito vectors.
What is the
basic transmission cycle for WNV?
Mosquitoes become infected by
feeding on birds with the virus circulating in their blood. After an
incubation period of 10 days to two weeks, the infected mosquitoes
can then transmit the virus to other animals or humans when biting to
take a second blood meal.
Why are
crows, but not most other dead birds, tested for WNV?
From 1999 - 2001, there was a
large die-off of crows from WNV in New Jersey and other states.
Although other birds can also become infected with the virus, the
mortality rate is much lower in other birds. Because crows are
extremely susceptible to WNV, they are very useful as sentinels to
monitor viral activity. In 2001, 1073 were confirmed positive for WNV
from 20 counties in New Jersey.
What other
kinds of surveillance are conducted to detect WNV activity in New Jersey?
As part of a multi-agency plan to
monitor WNV and prevent virus transmission in 2001, surveillance
activities were conducted in all 21 counties to detect and monitor
the virus in crows, hawks, falcons, urban birds, sentinel chickens,
horses and mosquitoes, as well as surveillance for human cases. A
total of 1073 birds (mostly crows) from 20 counties, 357 mosquito
pools from 20 counties, 31 sentinel chickens from Monmouth County and
9 humans (to date) were confirmed positive for WNV.
What agencies
conduct the surveillance and provide mosquito control services?
The WNV surveillance plan is
coordinated among a number of state and local agencies. They include
the Department of Environmental Protection (DEP), Office of Mosquito
Control and Coordination; NJ Department of Health and Senior Services
(DHSS); Department of Agriculture, Division of Animal Health; Rutgers
University, 21 county mosquito control agencies, local health
departments, physicians and hospitals, in addition to the national
Centers for Disease Control and Prevention (CDC) and other states in
the region.
The primary responsibility for
mosquito control rests with the 21 county mosquito control agencies.
Each agency conducts numerous activities that include: education,
surveillance, source reduction and biological and chemical control of
larval and adult mosquitoes.
Can West Nile
virus cause illness in dogs and cats?
The virus does not usually cause
illness in dogs and cats. WNV was isolated from a cat in Union
county, New Jersey in 1999, but this is the only case recorded in
cats. A serosurvey of dogs and cats in the New York WNV epidemic area
in 1999 showed a low infection rate in healthy dogs and cats. There
is no evidence that a dog or cat can transmit the virus to humans or
other animals.
What can I do
to reduce my risk of becoming infected with WNV?
Eliminate stagnant water around
the home in discarded tires, blocked gutters, unclean birdbaths,
poorly maintained pools, and any type of receptacle with decaying
organic matter. Limit outdoor activities at dawn, dusk and in the
early evening, when possible. Wear long-sleeved shirts and long pants
whenever you are outdoors. Make sure screen doors and windows are in
good condition. When outside, use an effective skin or clothing
mosquito repellent. Always use a repellent according to the
directions on the product label.
Who can I
contact to ask about mosquito control spraying in my area?
You can call your county mosquito
control agency. As the pesticide applicator, with professional staff
licensed to apply mosquito larvicides and adulticides, the county
agency can answer questions regarding insecticide applications in
your community.
