Facts and Fallacies
1. Bats Carry Rabies.
FALLACY. Bats are mammals and all mammals can contract rabies, however bats don’t naturally ‘carry’ the disease. In reality, bats catch rabies far less than other animals. Less than 1/2 of 1% of all bats may contract the disease. A variety of mammals can catch rabies, including foxes, skunks, raccoons, coyotes, bats, foxes, cats and dogs and even livestock.
2. Hundreds people die of bat rabies in the U.S. each year.
FALLACY. There is only one to two human deaths per year from bat rabies in the United States. A person living in the U.S. is more likely to catch polio, leprosy or the plague than to contract rabies from a bat. Throughout the world 30,000+ people die from the disease each year – 99% of these deaths come from contact with rabid dogs. In the United States, however, due to successful vaccination programs, contracting rabies from dogs and cats is now rare.
3. A person can be bitten by a bat and not even feel it.
FALLACY. Bat bites feel like sharp needle jabs. According to the United States Center of Disease Control and Prevention (CDC), most people usually know when they have been bitten by a bat. However, a bat bite can be superficial and not easily noticed. Bats have small teeth which may leave marks that are not easily seen, so there are situations in which you should seek medical advice even in the absence of an obvious bite wound. For example, if you awaken and find a bat in your room, see a bat in the room of an unattended child, or see a bat near a mentally impaired or intoxicated person, seek medical advice and have the bat tested.
4. You can catch rabies just by being near a bat.
FALLACY. Rabies is nearly always transmitted through a bite. Although rare, exposures can also occur from contact between infected saliva or nervous tissues and open wounds or the mucous membranes of the eyes, nose, or mouth. The principal source of rabies exposure from bats is through careless handling. According CDC, people cannot get rabies just from seeing a bat in an attic, in a cave, or at a distance. In addition, people cannot get rabies from having contact with bat guano (feces), blood, or urine, or from touching a bat on its fur (even though bats should never be handled!). The rabies virus has never been isolated from bat blood, urine or feces, and there is no evidence of air-borne transmission in buildings. Two cases of aerosol transmission were reported in the 1950s in Texas caves that support very unusual environments. However, no similar cases have occurred since, despite the fact that many thousands of people explore bat caves each year. No such transmission has occurred outside or in buildings.
5. Bats transmit rabies to other kinds of wildlife and domestic pets.
FALLACY. There is no evidence that rabies from bats has ever triggered an outbreak in other animals. It occasionally does spill over into other species, causing individual animals to die, but even this is apparently rare. Despite the fact that numerous carnivores gather to feed on the 20 million Mexican free-tailed bats at Bracken Cave, Texas, no outbreaks of rabies are known from this source. However, the presence or absence of bats is irrelevant to the fact that all dogs and cats should be vaccinated. Two cases have been documented of dogs contracting bat rabies variants between 2001-2010, and rabies transmission to cats has also been documented.
6. Bat colonies in urban settings lead to more cases of rabies.
FALLACY. The largest urban bat populations consist almost exclusively of colonial species, and there is no evidence linking them to increased transmission to humans. Tens of thousands of people have closely observed the emergence of 1.5 million Mexican free-tailed bats at the Congress Avenue Bridge in Austin, Texas each summer for over 16 years without incident. In fact, though Austin, San Antonio and several other Texas Hill Country towns likely support the highest bat densities in America, they have recorded no human cases of bat-transmitted rabies.
7. People catch rabies from bats more than any other animal in the U.S.
FACT. Bat rabies has been implicated in most human rabies cases acquired domestically in the United States during the last 25 years, however, this does not mean the disease is widespread. Unlike skunks, raccoons and other wildlife, the small size of North American bats makes them appear harmless so people may handle them unwisely. Additionally, people who have been bitten might not bother to seek the treatment necessary to save their lives. It’s important to remember that any grounded bat is more likely to be sick, therefore bats should never be rescued barehanded. Any bat that bites a human should be tested for rabies as soon as possible, and post-exposure treatment should begin immediately unless the bat is confirmed negative.
8. The media and health agencies always tells the truth about bats and rabies.
FALLACY. Although there are educated members of the media and health officials who provide factual information about bats and rabies, many incidents involving bats are ridiculously distorted, causing people to over-react in ways that increase rather than decrease the risk of contracting rabies. Over-the-top warnings made by a health officials who are ignorant of the facts also lead to increase risks of human/bat contact. Attempts to illegally poison or exclude bats from buildings using inappropriate methods can dramatically increase human contact, as sick or homeless bats scatter to exposed positions throughout entire neighborhoods where they are more likely to come into contact with children and pets.
9. Nothing can be done to prevent the transmission of rabies to humans.
FALLACY. The most progressive tool we can use to fight this disease is education and common sense. Keeping domestic pets vaccinated against rabies is also critical in rabies prevention. Understanding how to peacefully co-exist with bats, teaching children to never handle bats and never attempting to rescue a bat bare-handed will minimize the risk of contracting the disease. Ninety to 95% of sick bats are not rabid, but taking a careless chance on being bitten could prove fatal. Any animal bite (domestic or wild) should be reported immediately to a family physician or public health professional for evaluation as a possible rabies exposure.
10. Post-exposure rabies treatment is extremely painful
FALLACY. Vaccinations are no longer administered in the abdomen. Injections are typically administered in the upper-arm or thigh. To most people the injections are relatively painless, like a flu shot or a tetanus shot.
