Rabies affects only mammals. Mammals are warm-blooded animals with fur. People are also mammals. Birds, snakes, and fish are not mammals, so they can’t get rabies and they can’t give it to you. But any mammal can get rabies, including people. While rabies is rare in people in the United States, with only 1 to 3 cases reported annually, about 60,000 Americans get post-exposure prophylaxis (PEP) each year to prevent rabies infection after being bitten or scratched by an infected or suspected infected animal.
In the United States, more than 90% of reported cases of rabies in animals occur in wildlife. The wild animals that most commonly carry rabies in the United States are raccoons, skunks, bats, and foxes. Contact with infected bats is the leading cause of human rabies deaths in this country; at least 7 out of 10 Americans who die from rabies in the US were infected by bats. People may not recognize a bat scratch or bite, which can be very small, but these types of contact can still spread rabies.
Pets (like cats and dogs) and livestock (like cattle and horses) can also get rabies. Nearly all the pets and livestock that get rabies had not received vaccination or were not up to date on rabies vaccination. Most pets get rabies from having contact with wildlife.
You can’t tell if an animal has rabies by just looking at it—the only way to know for sure if an animal (or a person) has rabies is to perform laboratory testing. However, animals with rabies may act strangely. Some may be aggressive and try to bite you or other animals, or they may drool more than normal. (This is sometimes shown in movies as animals “foaming at the mouth.”) But not all animals with rabies will be aggressive or drooling. Other animals may act timid or shy, move slowly or act tame, or let you get close to them. Because that’s not the way wild animals usually act, you should remember that something could be wrong. Some animals may not appear ill. For the health and safety of wildlife, your pets, and yourself, leave wild animals alone, including baby animals.
There are several things you can do to protect your pet from rabies. These include making sure your pets get regular rabies vaccines, keeping pets away from wild animals, spaying or neutering pets, and calling animal control to remove stray animals from your neighborhood.
