Today is World Rabies Day!
I know it doesn't sound like a reason to celebrate (and it's not) but it's still an important reminder that a killer disease is still in our midst. Here's an article I wrote for the Miami Herald on this issue:
Several years ago a father and his young son brought me a small, black kitten they’d found in their yard just days before. Though initially vigorous and healthy, she’d begun to twitch her head ominously over the past 24 hours. What’s more, this formerly playful kitten now growled and hissed without provocation.
I asked all the questions veterinarians are trained to ask in these instances, including the most critical one: Did she bite anyone?
“No” came the ready reply. But I had reason to doubt. Gently, I asked the son if the marks on his hands were the result of her claws—or perhaps her teeth. He claimed she’d scratched him with her teeth but insisted they weren’t “bites.”
As all veterinarians are instructed to do in cases where rabies is a possibility, I called the local Health Department. After listening to my description of the situation the authorities recommended immediate brain tissue analysis…as in, euthanasia…now!
The kitten’s family quickly agreed and the child was dispatched to a nearby emergency room.
Meanwhile, the kitten’s veterinarian was charged with the grim task of administering an overdose of several medications, removing her tiny head, and braving Miami traffic to deliver it personally…on ice. It was an unpleasant day for me—one I’ll not soon forget.
Such is the level of emergency whenever anyone is exposed to a potentially rabid animal. While the measures may seem extreme, rabies is a notoriously incurable disease with only a handful of survivors for every few thousand infected. Why else would any self-respecting veterinarian subject an animal to sudden death in lieu of treatment?
Within several hours the lab concluded the kitten did not carry rabies. All that barbaric work for nothing, you may think. But what if she had? In the event of a confirmed diagnosis, everyone involved would have received a series of post-exposure vaccines (myself included, despite all the pre-exposure rabies vaccinations I’ve already suffered).
I’m telling you this macabre story because today is World Rabies Day. On this day veterinarians and public health officials exhort the public to remain vigilant of this killer virus, one still endemic to the US wildlife population and a threat to most of the world’s mammalian populations. For my part I could think of no better way to recruit your attention than to relate my gruesome tale.
Though rabies is rigidly controlled in the US, it’s nonetheless responsible for the death of two or three Americans every year—most of whom are unaware they’ve been exposed (just like my client’s son). Worldwide, this viral infection accounts for 55,000 deaths every year—all of which are 100% preventable. Sickeningly, it’s reported that one person dies of rabies every ten minutes, most of them in Asia and Africa.
Yet closer to home, it’s clear more work needs to be done. Though more than 90% of rabies in the US is found in wildlife species, dogs and cats are high-risk vectors whose domestic proximity to humans makes them ideal transmitters.
That’s why vaccinating our pets regularly (every one to three years) provides a huge epidemiological barrier against the spread of this disease to humans. But it’s not enough. Though Miami-Dade has been largely spared over the past twenty years (last year’s case of a man bitten by a rabid bat, notwithstanding), cases in Broward and Palm Beach Counties are on the rise. So what’s a community to do?
In a fiscal climate where budget cuts loom over all “non-essential” services, individual sacrifices are sometimes required to support a sagging state of affairs. License fees for pets help fund our animal shelters, provide the community with low-cost population control services and make rabies vaccines widely available. Yet only an estimated 30% of our area’s owned dogs are licensed. Presumably, a far smaller percentage of our total canine and feline population(s) are vaccinated against rabies.
Licensing and vaccination is a small sacrifice for pet owners (approximately $3-$40 a year in low-cost settings). How much more could our community accomplish in terms of rabies safety and humanitarian aid to needy animals if more of us elected to obey the law?
And then there’s our ability to simply pay attention. Knowing what’s at risk means we need to be aware of how the pets, feral cats and wildlife in our neighborhoods behave. Because rabies makes animals act erratically, the first sight of abnormal behavior should trigger the thought of rabies. Call your county’s Animal Services for assistance.
Should a bite actually occur, regardless of the offending species, it must be reported to your physician immediately. Not all rabid animals will display the same symptoms (or any) so that even bites from seemingly healthy, unvaccinated animals fall under this advisory.
Finally, remember my story and take this opportunity to discuss bites with your children. Knowing that kids often hide their run-ins with the animal kingdom, please make them aware of the risks they run if they don’t tell when they’ve been bitten…or even “scratched by teeth.” Rare as it may be to contract rabies, there’s no need to take a chance…is there?
Contact your county Animal Services division or any licensed veterinarian on how to keep your pets and our community safe through rabies vaccination.

I agree fully that we should do our part to keep both animals & humans safe from rabies.
Here's where I have concerns:
1. repeated vaccination thru life of elderly, sick, compromised, & debilitated pets
2. no governmental checks (licensing) of felines
3. feral feline population
4. importing canines from possible endemic areas by shelters
Other readers will have more comments & concerns, I'm sure.

The sacrifice of vaccination can cost much more than the $40. The sacrifice can also be vaccine associated sarcoma in cats as well as other adverse reactions in cats and dogs. In my state of Illinois, in the last 18 years 4 cats and 6 dogs have tested positive for rabies. The last case occuring over 12 years ago. The majority of rabies cases coming from bats.
It's ridiculous to me the frequency in which we vaccinate our animals. It defies the basics of immunology. The Rabies Challenge Fund is currently researching the duration of immunity which is expected to exceed 5+ years.
http://www.rabieschallengefund.org/index.html
Vaccination provides active immunity by "stimulation of the immune system to
produce antigen-specific humoral (antibody) and cellular
immunity...active immunity usually lasts for many years, often for a
lifetime."
http://www.cdc.gov/vaccines/pubs/pinkbook/download...
So why again are we vaccinating every year? Because the manufacturers are unwilling to fund the testing of immunity for animals longer than 1-3 years. Bare bones minimum.
Heather September 28th, 2008 02:00:00 PM
What about titres? Why aren't rabies titres accepted in lieu of vaccination?
Food for thought: I had to have titres done for all the diseases babies and children are vaccinated for due to my records being long gone. (I'm 45.) Every single one of them came back as being an appropriate antibody level.
Just sayin'.
Deanna September 28th, 2008 03:52:00 PM
Thanks for the reminder. Last year, my vet mentioned that there is an increase of rabid bats here in Michigan.

Thanks for the reminder :)
yasir September 28th, 2008 06:35:00 PM
Dr. Khuly, I have a question.
From my understanding, unvaccinated animals who bite are generally quarantined and if they continue to show possible symptoms after 10 days, they then have their brains analyzed?
Is it standard operating procedure in Miami to immediately analyze the brain? Or was it something about this particular case (such as the growling without provocation) that caused the authorities to recommend immediate analysis?
Just curious.
MichiganPetLover September 28th, 2008 07:46:00 PM
Good reminder of why Rabies vaccination is so important, Dr. Patty! Although I also would be interested as to why titers aren't more accepted - aren't they used in humans to determine when you need a pre-exposure booster? It would seem if they're accurate enough for a high-risk human, they'd be accurate enough for a dog or cat.
I don't, however, think there is much correlation between licensing rates and vaccination rates. When you wrote: "Yet only an estimated 30% of our area’s owned dogs are licensed. Presumably, a far smaller percentage of our total canine and feline population(s) are vaccinated against rabies." I know the "far smaller percentage" you speak of includes feral animals and strays. But still... lots of pets are vaccinated but not licensed in every city. It's more of a problem in some cities than others. A lot depends on the perceived value of the licensing fee and also of the perceived risk. For example, there is a restriction on pit bulls in Miami. So, if I lived there and had a pit bull, I would vaccinate him (traveling to a vet in a nearby suburb if necessary) but wouldn't license him. I think most of us have heard that when Denver decided to enforce their pit bull ban that had been on the books but not enforced for many years, the first thing they did was look at the licensing list and knock on the doors of people who had one of the banned breeds.
Not everyone can afford to move if your city passes a law banning your breed, or placing a limit on the number of pets you can keep that is lower than the number you already have. But if your pets are licensed, they'll know where you are!
Barb September 28th, 2008 10:33:00 PM
This topic reminds me of a question I've been meaning to ask you, maybe as a topic for a future post: Under what circumstances would you write a letter exempting a pet from a rabies vaccination for health reasons - provided that the local ordinance allowed such an exemption.
Ditto for writing an exemption from mandatory spay or neuter for health reasons - many such laws will allow exemtion if the owner has a statement from a vet (mostly to avoid lawsuits, I imagine).
I understand that no ethical vet would write such an exemption lightly - but are there cases where you would write one?
Barb September 28th, 2008 10:43:00 PM
As a young nursing student more than 30 years ago, I watched a patient die after contracting rabies, and when one of my ER patients balks at post-exposure vaccines, I let them know in no uncertain terms that this disease is virtually 100% fatal. Here in western PA, the vast majority of rabies cases occur in bats, skunks, foxes, and raccoons. So, even though my animals are vaccinated, I live in the country; and am always vigilant about my animals possibly having contact with one of the vector species.
One Sunday afternoon two years ago, I came home from church to find a staggering, hissing, snarling raccoon on my front porch, in broad daylight, at NOON. I attempted to chase it away as my dogs needed to go out; with noise, tossing rocks, and a long-handled broom; to no avail. It stood its ground, attacking the small rocks I pelted it with and charging the broom. I called the local police for animal control; our local animal-control officer was in the hospital for surgery and unavailable, and my husband was (of course) out of town. So I did what I felt I needed to do to protect myself and my pets. I went into the house through the garage, and into my husband's gun cabinet. (He is a hunter, I'm not, although I used to be. I personally don't like the idea of killing another living being, but know how to use both rifles and handguns). I loaded the .22, and went back out the way I came in, still dressed in my Sunday best. By this time the raccoon was under the shrubs beside the garage, still snarling, but I could see his gait was unsteady, and he didn't look "normal". So I shot and killed him, then went back in the house, double-gloved, and then double-bagged him. I then called the Health Department, who refused to test the animal "since no-one was bitten or harmed", unless I was willing to pay $100 for the testing. I then had to take it to a safe area, douse it with gasoline, and incinerate the corpse; afterward I buried the remains. I will never know for sure, but suspect that the raccoon was rabid, given its completely abnormal behavior.
Oddly enough, just this July we had a similar scenario to yours at our shelter. A formerly pleasant and even-tempered cat we had spayed the day before developed anorexia and tremors, as well as appearing to be blind, staggering and banging into the sides of her cage. The cat was euthanized and the head sent for testing. As in your case, the test came back negative, but those of us who had handled the cat had an anxious day waiting for the results to know if we needed the post-exposure vaccine series. I'm sorry the kitty lost her life, but having seen firsthand the devastating effects of human rabies, I never question the necessity of the testing if there is any possibility of exposure.
Shellie September 29th, 2008 01:16:00 AM
Barb: On licensing and rabies vaccination. We vaccinate for rabies every three years but pets must be licensed every single year. Our hospital will not vaccinate for rabies without issuing a license. Technically, it's not legal to do so. Recently, however, I discovered a loophole: If you are homeless you may receive a certificate and no actual license. Otherwise, rabies vaccine = license. Ergo, if only 30% of our area's dog owners have licenses, it stands to reason that only 30% have been vaccinated at least every three years. Less than that if you consider all the cats (who don't require licenses) and the pets who roam the streets and are not considered "owned."
Dr. Patty Khuly September 29th, 2008 08:39:00 AM
On titers: Though we vaccinate every three years, a significant rabies titer is good enough for me. It costs about five times as much as the actual vaccine but it's a perfectly acceptable alternative for pets who have received at least 2 vaccines already.
Barb: On the "exemption" for rabies vaccination: I do this frequently.
1) When the owner agrees to a titer in lieu of vaccination (as in the above scenario).
2) When the pet suffers from an acute or chronic disease that renders vaccination unwise (and the animal is under my care).
3) When the animal is over ten and a patient I see regularly, I usually stop vaccinating.
I don't always require titers in the last two cases. If these are pets I'm caring for on a regular basis and they've received vaccines in the past, I'm comfortable not vaccinating them.
Dr. Patty Khuly September 29th, 2008 08:47:00 AM
Michigan Pet Lover: If the animal is 1) presumably unvaccinated, 2) shows neurological signs and 3) bites a child, we don't wait around to see if he "looks" rabid (which what the quarantine period is for). After all, the signs we're looking for are already present--no need to monitor the animal. Rabies is already considered a serious possibility in these cases.
If an already-neurological unvaccinated animal had not bitten anyone and the owner wanted to attempt treatment we would be happy to do so--taking great care, of course, and with the understanding that if the animal DID manage to bite someone that euthanasia would be required for the safety of our staff.
Even in this case, where the child was bitten, I believe it's up to the owners to make the decision for euthanasia. the child could have received the complete series of rabies vaccines as a follow-up while we treated the kitten (no law is forcing me to kill an animal in these cases) but I would NEVER do so without a host of signatures proving to me and to any court of law that the owners of the kitten understand that the child MUST immediately be remanded to a doctor's care (something I recommend in the event of ANY bite, anyway).
Dr. Patty Khuly September 29th, 2008 09:28:00 AM
My vet, who I personally like very much and has always answered questions appropriately to my knowledge, vaccinates my dogs for rabies first with a one year vaccine and subsequent times with a 3 year vaccine. Are there really two different vaccines? My understanding is these vaccines are not tested for duration, so I would be pleasantly surprised.
Also, she seems to want to give yearly titers if the other (parvo, etc) vaccines are not given. I think the titers are about $80. Will still probably prefer titers over vaccines but it adds up with multiple dogs.
They are active outdoorsy dogs so we do get lepto and lyme vaccines yearly.
Erich Riesenberg September 29th, 2008 10:31:00 AM
Yep. Rabies vaccines ARE tested for length of active immunity.
On titers: I should be more specific on this. I will run titers for rabies because they are frequently used in legal and regulatory settings but let me be clear: Titers are NOT considered effective for determining whether adult animals are protected or not. I still prefer to vaccinate my patients for rabies every three years. I believe it provides a safer measure of protection.
For more common diseases like parvo and distemper, for which many vets are now running titers
are not only not necessary every year if the vaccines are approved for three years, they ARE NOT CONSIDERED RELIABLE TO CONFIRM PROTECTION.
This brings up a big misconception in veterinary circles. I used to do a lot of titering of distemper and parvo before I attended a lecture on this at a conference a year or so back and became convinced that even with an excellent lab (such as Cornell's) that provides a numerical value for titers (as opposed to a "positive" or "negative"), there's no way to know if this means the animal is protected.
In fact, neither the AAFP (American Association of Feline Practitioners, huge proponents of low-frequency vaccinations), the AVMA or AAHA (American Animal Hospital Association) advocate running titers on pets. They just don't tell us much about REAL immunity.
Not to say that your vet is doing so, but I believe that many vets use yearly titers to make up for the income they're losing because they're not vaccinating annually anymore. After all, if the vaccines are approved for three years then WHY titer?
The only reason to titer is because it's proof, in the case of rabies, at least, that the animal has been vaccinated at some point (something municipalities, states and other governing bodies want to know). But it doesn't PROVE that the animal cannot become diseased with the agent its been innoculated against.
I should write a whole post on this, I think.
Dr. Patty Khuly September 29th, 2008 11:17:00 AM
i have a cat with a supressed immune system due to HCM and asthma so i am extremely afraid of vaccinating her she is stable and doing well but its a boat i do not want to rock not to mention VAS. for me it has nothing to do with cost. i willing pay for twice yearly bloodwork and echos and if anything goes wrong i am the one who is rushing my baby to the vet. i worry about causing her more harm. i asked my vet about titers and they just arent accepted especially for felines which is a bummer.
katy September 29th, 2008 12:03:00 PM
Katie: That doesn't mean she absolutely has to be vaccinated. If she's an indoor cat with no exposure to other unvaccinated cats (and I'd expect she would be with her issues) then you have a perfectly good excuse not to vaccinate her--ever. I'd probably still opt for 2 rabies vaccines early in her life. After that--nothing for my asthma cases.
Dr. Patty Khuly September 29th, 2008 01:11:00 PM
I read on a web site once that titers are appropriately given after a vaccination, to show a immune response has been stimulated, and that titers in the future do not show lasting immunity, similar to what you are saying. I think my vet does get a numerical number. This is the first year I have not given the vaccines (two dogs I just got a year ago) so I was okay with the titers.
After a couple sets of the basic vaccines do you just stop giving the vaccines, with the assumption the animal is immune (except for rabies, lepto and lyme)?
I really like my vet, I think she works probably a lot like you, very easy to talk with, and this is the first thing that has come up where I think she might be wrong, though titers are apparently becoming more common. I can see why people get confused. Thanks for the post, an article on correct titering would be great.
Erich Riesenberg September 29th, 2008 01:13:00 PM
Thanks for this post. It frightens me how many people I see on various internet communities saying things like rabies is practically non-existent in the US. Um, no. It's actually on the rise.
Recently there was a kitten with confirmed rabies a few counties from where I am. We had a client come in to work whose Spaniel had been bitten four times by a raccoon on the owner's porch in the middle of the day. The coon was not cornered and the owner said that it had no reason to bite instead of leave. He was afraid he was going to be bitten next. Thankfully he wasn't, and thankfully the dog was vaccinated. Scary stuff.
katie September 29th, 2008 01:25:00 PM
dr. patty khuly you are right she is strickly indoor, with no other pets (im so bad that i wont let people with pets in my home who dont vaccinate just in case~ anal i know but im not taking chances, i brush her teeth so she wont need dentals...im the crazy cat lady forsure :). i did get her vaccinated until 16 months when her HCM was diagnosed. then at 3 she was diagnosed with asthma as well. she will only be 6 in april. the vets office agrees that vaccinating her is probably not the best for her and she sees her vet minimum twice a year and her cardiologist twice a year too. i still wish there was a way to know true immunity. i know some people are not willing to pay the extra costs that this kind of testing would cause but i am not one of them.
katy September 29th, 2008 01:40:00 PM
Barb,
I agree with you. My cats are vaccinated against rabies (for legal reasons and because they are routinely exposed to potentially unvaccinated carriers of rabies in the form of a constant stream of foster cats) and are not liscenced. They aren't because the only reason I can get out of the municipal SPCA is that the purpose for liscening them is for identification purposes. My cats both wear quick release collars with tags and are microchipped in the unlikely event that they get out of my house and run away.
This summer however, the city hired students who according to an article in a local paper, were given specific instructions to peer into peoples houses to look for evidence of pet ownership including nose smudges on the glass, pet waste in the green bin or with the garbage and cat or dog doors. In the media the city equated unliscence pets to those having irresponsible owners. My cats are appropiately cared for including appropiate vaccinations as decided between me and my vet. The city has no right to blantantly invade my privacy as they did this summer.
Shannon September 29th, 2008 02:01:00 PM
katy: True immunity cannot be determined because titers can't measure "cell mediated immunity," the kind of immunity that's actually protective. B-cell immunity is what we measure. It's even possible to have no titer (no measurable B cell immunity) and still have perfect protection. In your case, measuring her degree of immunity sounds like an academic exercise anyway. If she's not exposed to disease there's no need to vaccinate then, is there? You just have to be extra careful to keep her closeted.
Dr. Patty Khuly September 29th, 2008 03:04:00 PM
Shannon: That's horrible! What a blatant violation of privacy! There has to be a better way.
I don't agree, however, that cats should not be licensed. I realize it's an unpopular stance but it IS a way to 1) fund animal services, 2) grant cats the legitimacy they deserve in our culture, and 3) protect both cats and their people from disease.
Sure, there are a lot of downsides to licensing, not the least of which is a tremendous hassle to the pet owner to provide public funds which are often mismanaged. But is there another way? I'm happy to explore alternatives if you can think of any.
Dr. Patty Khuly September 29th, 2008 03:10:00 PM
Dr. Khuly, I so very much appreciate your candidness & clarity. Here in New Hampshire, licensing is only for dogs, although the law states felines & ferrets must be rabies vaccinated also.
An interesting revision to the NH rabies law passed 1/08, allows for exemption as determined by the patient/client veterinarian whether chronic or temprorary illness prohibits safe vaccination.
This is all beneficial for the pets, however, a second & third signature is needed by a DAVIM, and the state veterinarian----both who will never see the pet, but have the ability to nix the NH attending licensed vet.
And as far as illness, that part of the law is not clarified. I will gladly do titers in lieu of vaccine! And with my three elderly 11 1/2 & 11 yr.olds, one with liver disease, one with cancer, and one with residual hind-end weakness post-IVDD---I would think they should qualify!
Oh, not too mention that chance of exposure is slim to none---thanks again, great posts
Barbara A. Albright/New Hampshire September 29th, 2008 05:12:00 PM
Dr K,
No one has ever given me a good enough reason to liscence my cats. I'm not against it per say. If they were outdoor animals, more likely to need the services of the SPCA I would be more willing to. If I was seeing some sort of benefit for pet owners from the financial contribution, I would be more willing to. As it is, our municipality has recently shut down a satelite location of their shelter and is closing down off-leash dog parks everywhere.
I've never thought of it as a tool to give our cats the legitimacy they deserve but I can see how it would be helpful.
And finally, where I live its not really a tool to prevent diseases as the form you need to complete to get a municipal liscence doesn't require proof of rabies vaccination. In fact from what I can gather in some really quick fact finding reasearch, it is only required to vaccinate your dog against rabies at 3 months of age and administer another booster by the date specified in the certificate of immunization that is issued for that dog which given the 3 year rabies vaccines is only every three years. I'm only guessing that the same law applies to cats. Municipal liscences need to be renewed annually so the two things don't interconnect very well.
Do I have a solution? Unfortunately not.
