Compendium of Animal Rabies Control, 1996
National Association of State Public Health Veterinarians, Inc. *
The purpose of this Compendium is to provide information on
rabies to
veterinarians, public health officials, and others concerned with
rabies
control. These recommendations serve as the basis for animal
rabies-control
programs throughout the United States and facilitate
standardization of
procedures among jurisdictions, thereby contributing to an
effective
national rabies-control program. This document is reviewed annually
and
revised as necessary. Recommendations on immunization procedures
are
contained in Part I; all animal rabies vaccines licensed by the
United
States Department of Agriculture (USDA) and marketed in the United
States
are listed in Part II; Part III details the principles of rabies
control.
Part I: Recommendations for Immunization Procedures
Vaccine Administration
All animal rabies vaccines should be restricted to use by, or
under the
direct supervision of, a veterinarian.
B. Vaccine Selection
In comprehensive rabies-control programs, only vaccines with a
3-year
duration of immunity should be used. This procedure constitutes the
most
effective method of increasing the proportion of immunized dogs and
cats in
any population. (See Part II.)
C. Route of Inoculation
All vaccines must be administered in accordance with the
specifications
of the product label or package insert. If administered
intramuscularly, it
must be at one site in the thigh.
D. Wildlife Vaccination
Parenteral vaccination of captive wildlife is not recommended
because
the efficacy of rabies vaccines in such animals has not been
established
and no vaccine is licensed for wildlife. For this reason and
because
virus-shedding periods are unknown, wild or exotic carnivores and
bats
should not be kept as pets. Zoos or research institutions may
establish
vaccination programs that attempt to protect valuable animals, but
these
programs should not be in lieu of appropriate public health
activities that
protect humans. The use of licensed oral vaccines for the mass
immunization
of wildlife should be considered in selected situations, with the
approval
of the state agency responsible for animal rabies control.
E. Accidental Human Exposure to Vaccine
Accidental inoculation can occur during administration of
animal rabies
vaccine. Such exposure to inactivated vaccines constitutes no risk
for
acquiring rabies.
F. Identification of Vaccinated Animals
All agencies and veterinarians should adopt the standard tag
system.
This practice will aid the administration of local, state,
national, and
international rabies-control procedures. Animal license tags should
be
distinguishable in shape and color from rabies tags. Anodized
aluminum
rabies tags should be no less than 0.064 inches in thickness.
Rabies Certificate. All agencies and veterinarians should
use the
National Association of State Public Health Veterinarians,
Inc.
(NASPHV) form #51, Rabies Vaccination Certificate, which
can be
obtained from vaccine manufacturers. Computer-generated
forms
containing the same information are acceptable.
Part II: Vaccines Marketed in the United States and NASPHV
Recommendations
Human Rabies Prevention. Rabies in humans can be prevented
either
by eliminating exposures to rabid animals or by providing
exposed
persons with prompt local treatment of wounds combined with
appropriate passive and active immunization. The rationale
for
recommending preexposure and postexposure rabies
prophylaxis and
details of their administration can be found in the current
recommendations of the Advisory Committee on Immunization
Practices
(ACIP) of the Public Health Service (PHS). These
recommendations,
along with information concerning the current local and
regional
status of animal rabies and the availability of human
rabies
biologics, are available from state health departments.
Rabies in Domestic Animals. Local governments should
initiate and
maintain effective programs to ensure vaccination of all
dogs and
cats and to remove strays and unwanted animals. Such
procedures in
the United States have reduced laboratory-confirmed rabies
cases in
dogs from 6,949 in 1947 to 153 in 1994. Because more rabies
cases
are reported annually involving cats than dogs, vaccination
of cats
should be required. The recommended vaccination procedures
and the
licensed animal vaccines are specified in Parts I and II of
the
Compendium.
Rabies in Wildlife. The control of rabies among wildlife
reservoirs
is difficult. Vaccination of free-ranging wildlife or
selective
population reduction may be useful in some situations;
however, the
success of such procedures depends on the circumstances
surrounding
each rabies outbreak. (See C. Control Methods in Wildlife.)
Control Methods in Domestic and Confined Animals
Preexposure Vaccination and Management. Animal rabies
vaccines
should be administered only by, or under the direct
supervision of,
a veterinarian. This is the only way to ensure that a
responsible
person can be held accountable to assure the public that
the animal
has been properly vaccinated. Within 1 month after primary
vaccination, a peak rabies antibody titer is reached and
the animal
can be considered immunized. An animal is currently
vaccinated and
is considered immunized if it was vaccinated at least 30
days
previously and if all vaccinations have been administered
in
accordance with this Compendium. Regardless of the age at
initial
vaccination, a second vaccination should be given 1 year
later.
(See Parts I and II for recommended vaccines and
procedures.)
Dogs and Cats. All dogs and cats should be vaccinated
against
rabies at 3 months of age and revaccinated in
accordance with
Part II of this Compendium. If a previously vaccinated
animal
is overdue for a booster, it should be revaccinated
with a
single dose of vaccine and placed on an annual or
triennial
schedule depending on the type of vaccine used.
Ferrets. Ferrets may be vaccinated against rabies at 3
months
of age and revaccinated in accordance with Part II of
this
Compendium.
Livestock. It is neither economically feasible nor
justified
from a public health standpoint to vaccinate all
livestock
against rabies. However, consideration should be given
to the
vaccination of livestock, especially animals that are
particularly valuable and/or might have frequent
contact with
humans, in areas where rabies is epizootic in
terrestrial
animals.
Other Animals
Wild. No parenteral rabies vaccine is licensed for
use in
wild animals. Because of the risk of rabies in wild
animals
(especially raccoons, skunks, coyotes, foxes, and
bats),
the American Veterinary Medical Association (AVMA),
the
NASPHV, and the Council of State and Territorial
Epidemiologists (CSTE) strongly recommend the
enactment of
state laws prohibiting the importation,
distribution,
relocation, or keeping of wild animals and wild
animals
that are crossbred to domestic dogs and cats as
pets.
Maintained in Exhibits and in Zoological Parks.
Captive
animals that are not completely excluded from all
contact
with rabies vectors can become infected. Moreover,
wild
animals can be incubating rabies when initially
captured;
therefore, wild-caught animals susceptible to
rabies should
be quarantined for a minimum of 180 days before
exhibition.
Employees who work with animals at such facilities
should
receive preexposure rabies immunization. The use of
preexposure or postexposure rabies immunizations of
employees who work with animals at such facilities
might
reduce the need for euthanasia of captive animals.
Stray Animals. Stray dogs or cats should be removed from
the
community, especially in areas where rabies is epizootic.
Local
health departments and animal-control officials can enforce
the
removal of strays more effectively if owners either confine
their
animals or keep them on a leash. Strays should be impounded
for at
least 3 days to determine if human exposure has occurred
and to
give owners sufficient time to reclaim animals.
Quarantine
International. CDC regulates the importation of dogs
and cats
into the United States, but current PHS regulations (42
CFR No.
71.51) governing the importation of such animals are
insufficient to prevent the introduction of rabid
animals into
the country. All dogs and cats imported from countries
with
enzootic rabies should be currently vaccinated against
rabies
as recommended in this Compendium. The appropriate
public
health official of the state of destination should be
notified
within 72 hours of any unvaccinated dog or cat imported
into
his or her jurisdiction. The conditional admission of
such
animals into the United States is subject to state and
local
laws governing rabies. Failure to comply with these
requirements should be reported promptly to the
Division of
Quarantine, CDC, 404-639-8107.
Interstate. Prior to interstate movement, dogs and cats
should
be currently vaccinated against rabies in accordance
with the
Compendium's recommendations. (See B.1. Preexposure
Vaccination
and Management.) Animals in transit should be
accompanied by a
currently valid NASPHV Form #51, Rabies Vaccination
Certificate.
Adjunct Procedures. Methods or procedures that enhance
rabies
control include the following:
Licensure. Registration or licensure of all dogs and
cats can
be used to aid in rabies control. A fee frequently is
charged
for such licensure, and revenues collected are used to
maintain
rabies or animal-control programs. Vaccination is an
essential
prerequisite to licensure.
Canvassing of Area. House-to-house canvassing by
animal-control
personnel facilitates enforcement of vaccination and
licensure
requirements.
Citations. Citations are legal summonses issued to
owners for
violations, including the failure to vaccinate or
license their
animals. The authority for officers to issue citations
should
be an integral part of each animal-control program.
Animal Control. All communities should incorporate
stray animal
control, leash laws, and training of personnel into
their
programs.
Postexposure Management. Any animal bitten or scratched by
a wild,
carnivorous mammal (or a bat) not available for testing
should be
regarded as having been exposed to rabies.
Dogs and Cats. Unvaccinated dogs and cats exposed to a
rabid
animal should be euthanized immediately. If the owner
is
unwilling to have this done, the animal should be
placed in
strict isolation for 6 months and vaccinated 1 month
before
being released. Animals with expired vaccinations need
to be
evaluated on a case-by-case basis. Dogs and cats that
are
currently vaccinated should be revaccinated
immediately, kept
under the owner's control, and observed for 45 days.
Livestock. All species of livestock are susceptible to
rabies;
cattle and horses are among the most frequently
infected.
Livestock exposed to a rabid animal and currently
vaccinated
with a vaccine approved by USDA for that species should
be
revaccinated immediately and observed for 45 days.
Unvaccinated
livestock should be slaughtered immediately. If the
owner is
unwilling to have this done, the animal should be kept
under
close observation for 6 months.
The following are recommendations for owners of
unvaccinated
livestock exposed to rabid animals:
If the animal is slaughtered within 7 days of being
bitten,
its tissues may be eaten without risk of infection,
provided liberal portions of the exposed area are
discarded. Federal meat inspectors must reject for
slaughter any animal known to have been exposed to
rabies
within 8 months.
Neither tissues nor milk from a rabid animal should
be used
for human or animal consumption. However, because
pasteurization temperatures will inactivate rabies
virus,
drinking pasteurized milk or eating cooked meat
does not
constitute a rabies exposure.
It is rare to have more than one rabid animal in a
herd or
to have herbivore-to-herbivore transmission;
therefore, it
may not be necessary to restrict the rest of the
herd if a
single animal has been exposed to or infected by
rabies.
Other Animals. Other animals bitten by a rabid animal
should be
euthanized immediately. Such animals currently
vaccinated with
a vaccine approved by USDA for that species may be
revaccinated
immediately and placed in strict isolation for at least
90
days.
Management of Animals That Bite Humans. A healthy dog or
cat that
bites a person should be confined and observed for 10 days;
it is
recommended that rabies vaccine not be administered during
the
observation period. Such animals should be evaluated by a
veterinarian at the first sign of illness during
confinement. Any
illness in the animal should be reported immediately to the
local
health department. If signs suggestive of rabies develop,
the
animal should be euthanized, its head removed, and the head
shipped
under refrigeration for examination by a qualified
laboratory
designated by the local or state health department. Any
stray or
unwanted dog or cat that bites a person may be euthanized
immediately and the head submitted as described above for
rabies
examination. Other biting animals that might have exposed a
person
to rabies should be reported immediately to the local
health
department. Prior vaccination of an animal may not preclude
the
necessity for euthanasia and testing if the period of virus
shedding is unknown for that species. Management of animals
other
than dogs and cats depends on the species, the
circumstances of the
bite, and the epidemiology of rabies in the area.
Control Methods in Wildlife
The public should be warned not to handle wildlife. Wild
mammals (as
well as the offspring of wild species crossbred with domestic dogs
and
cats) that bite or otherwise expose people, pets, or livestock
should be
considered for euthanasia and rabies examination. A person bitten
by any
wild mammal should immediately report the incident to a physician
who can
evaluate the need for antirabies treatment. **
Terrestrial Mammals. Continuous and persistent
government-funded
programs for trapping or poisoning wildlife are not cost
effective
in reducing wildlife rabies reservoirs on a statewide
basis.
However, limited control in high-contact areas (e.g.,
picnic
grounds, camps, or suburban areas) might be indicated for
the
removal of selected high-risk species of wildlife. The
state
wildlife agency and state health department should be
consulted for
coordination of any proposed vaccination or
population-reduction
programs.
Bats. Indigenous rabid bats have been reported from every
state
except Alaska and Hawaii and have caused rabies in at least
22
humans in the United States. However, it is neither
feasible nor
desirable to control rabies in bats by programs to reduce
bat
populations. Bats should be excluded from houses and
surrounding
structures to prevent direct association with humans. Such
structures should then be made bat-proof by sealing
entrances used
by bats.
