A CUP OF HEALTH WITH CDC
Preventing Rabies
April 13, 2007
[Announcer] This podcast is presented by the Centers for Disease Control and
Prevention. CDC – safer, healthier people.
[Matthew Reynolds] Welcome to A Cup of Health with CDC, a weekly broadcast
of the
MMWR, the Morbidity and Mortality Weekly Report. I’m your host, Matthew
Reynolds.
If you have a pet at home, you probably know how important it is to get them
vaccinated
against rabies. In fact, the rabies shot is required for dogs and cats in most
places.
Rabies is spread by the bite of an infected animal. The virus is most common
in wild
animals, but globally most human cases are still caused by dog bites. If you
have a dog,
cat, or ferret make sure you keep their vaccinations up-to-date. Also, keep
your pet
away from wild animals.
Each year more than $300 million is spent to prevent rabies. And for good reason —
rabies is fatal. Rabies is not very common in humans in the United States,
but tens of
thousands of people die from it in developing countries.
Here to speak with us today about rabies and how to protect ourselves and our
pets is
Dr. Charles Rupprecht, an expert from CDC on rabies prevention and control.
Welcome to the show, Dr. Rupprecht.
[Dr. Rupprecht] Thank you, Matthew. It’s a pleasure to be here.
[Matthew Reynolds] Dr. Rupprecht, I thought that rabies wasn’t really
a problem in the
United States, but if we’re spending $300 million a year on preventing
this disease
rabies must be a bigger threat than I realized. How big a problem is rabies
and where
does all that money go?
[Dr. Rupprecht] Rabies is a disease of nature and although human rabies cases
are no
longer common there are reservoirs among wildlife, such as raccoons, skunks,
foxes,
and bats, and whenever anybody gets exposed or a pet is attacked, a large number
of
things come into play. The animal has to be captured. The animal has to be
submitted
for diagnoss. People have to be evaluated for prophylaxis or vaccination. So
there are a
large number of variables or expenditures that occur any time an animal is
suspected of
having the disease.
[Matthew Reynolds] What would you say to the person who is listening to this
and
asking if you are going to treat rabies anyway, why should I bother with a
vaccination for
my pet?
[Dr. Rupprecht] Well Matthew, that’s a very good question. There is really
no treatment
for rabies. Once clinical signs of the disease develop, it’s essentially
fatal. When we’re
talking about treatment, we’re talking about wound care for the animal
that’s been
attacked, immediate first aid, and if the animal’s been vaccinated, it
will be boostered. If
the animal has not been vaccinated for rabies, there are only two recommendations.
Either euthanasia because of the possibilities of it developing rabies and
exposing
members of the family, or keeping that animal under strict quarantine for at
least 6
months.
[Matthew Reynolds] Would I be able to tell if an animal was infected with rabies?
The
common image I’ve heard is of a dog foaming at the mouth, but I suspect
it might not be
that obvious.
[Dr. Rupprecht] A lot of us tend to think of Cujo or To Kill a Mockingbird
and these
raging maniacal dogs. That’s probably not the way that we’re going
to encounter rabies.
In fact, the only characteristic thing about rabies is that it’s uncharacteristic
in the way
that it presents, and so sometimes, wild animals may present more accustomed
to
people or unafraid of them, and sometimes our pets, if they were infected,
may actually
become more aggressive.
[Matthew Reynolds] As serious as rabies is, it seems like preventing it is
the best
strategy. I know that visits to the vet are often expensive and time consuming
and I can
see where some people might be tempted to skip pet vaccinations. How important
is it
to vaccinate our pets?
[Dr. Rupprecht] That’s a very good question Matthew. What we want to
do is to set up a
barrier between ourselves and potentially rabid wildlife. One of the best single
things we
can do is to vaccinate our pets and set that up as a barrier between ourselves
and the
disease.
[Matthew Reynolds] What should a person do if their pet is attacked by a wild
animal?
[Dr. Rupprecht] Being attacked by any animal is not only frightening, but also
potentially
an emergency situation. There are two primary things that one wants to do.
We want to
be able to get our pet to the veterinarian as soon as possible for any emergency
care, to
check on the vaccination status of our pet, and booster those vaccinations
if necessary.
The second thing is to contact our local animal control authorities to not
only remove
that potentially rabid animal from the community, but also have it sent for
diagnoses to
see if the animal is rabid and if our pet needs to be boostered with a vaccination
or not.
[Matthew Reynolds] When it comes to the risk of rabies in humans, are there
certain
animals that cause greater concern?
[Dr. Rupprecht] In developing countries, we’re most concerned about rabid
dogs. In
developed countries, such as the United States, the animals that are responsible
for
maintaining the disease in nature tend to be carnivores, such as skunks, raccoons,
foxes, and bats.
[Matthew Reynolds] What should someone do if they have been bitten by an animal
that
might be infected?
[Dr. Rupprecht] One of the single most important things to do is proper wound
care after
you’re bitten by a potentially rabid animal. That means cleaning the
wound well with
soap and water. After that, seek medical attention, and at the same time, either
you or
someone in your family or neighborhood contact local animal control authorities
to try
and capture the animal. That will not only remove the risk in the neighborhood,
that will
also allow the animal for evaluation to see if you may need rabies vaccination.
[Matthew Reynolds] Dr. Rupprecht, thank you for taking the time to talk with
us today.
[Dr. Rupprecht] You’re welcome, Matthew. Thank you for inviting me.
[Matthew Reynolds] Well, that’s it for this week’s show. Don’t
forget to join us next
week. Until then, be well. This is Matthew Reynolds for A Cup of Health with
CDC.
