Animal Bite

Is this your symptom?

• Bite from a pet, wild animal (or human)
• Any animal-related skin injury

Types of Wounds

• Bruise. There is no break in the skin. No risk of infection.
• Scrape (Abrasion) or Scratch. A wound that doesn't go all the way through the skin. Low chance of infection. Antibiotic drugs are not needed.
• Cut (Laceration). A wound that goes through the skin to the fat or muscle tissue. Some chance of infection. Cleaning the wound can help prevent this. Most need to be seen. Antibiotic drugs may be needed.
• Puncture Wound. These wounds break through the skin. Greater risk of infection. Puncture wounds from cat bites are more likely to get infected. Antibiotic drugs may be needed.
• Wound Infection. This is the main risk of an animal or human bite. The main finding is redness around the bite and pain. It starts 8 hours to 3 days after the bite. It can often be prevented by early, careful cleaning of the bite. This is why most animal and human bites need to be seen.

Types of Animal Bites

• Large Wild Animal Bites. Rabies is a disease that can kill people. Bites or scratches from any large wild animal can pass on rabies. Animals at highest risk are bats, skunks, raccoons, foxes, or coyotes. These animals may spread rabies even if they have no symptoms.
• Small Wild Animal Bites. Small animals such as mice, rats, moles, or gophers do not carry rabies. Chipmunks, prairie dogs, squirrels and rabbits also do not carry rabies. Exception: one of these small animals actually attacks a human (an unprovoked bite). Sometimes, their bites can get infected.
• Large Pet Animal Bites. Most bites from pets are from dogs or cats. Bites from other pets such as horses can be handled using this guide. Dogs and cats are free of rabies in most U.S. and Canadian cities. Stray animals are always at risk for rabies until proven otherwise. Cats and dogs that always stay indoors should be safe. The main risk in pet bites is wound infection, not rabies. Cat bites become infected more often than dog bites. Cat scratches can get infected just like a bite because cats lick their claws.
• Small Indoor Pet Animal Bites. Small indoor pets are not at risk for rabies. Examples of these pets are gerbils, hamsters, guinea pigs, or mice. Tiny puncture wounds from these small animals also don't need to be seen. They carry a small risk for wound infections.
• Human Bites. Most human bites occur during fights, especially in teenagers. Sometimes a fist is cut when it strikes a tooth. Sometimes a tooth or tooth fragment breaks off and can get embedded in the wound. Human bites are more likely to become infected than animal bites. Bites on the hands are at higher risk.
• Bat Bites and Rabies. In the U.S., 90% of cases of rabies in humans are caused by bats. Bats have spread rabies without a visible bite mark.

Animals at Risk for Rabies

• Bat, skunk, raccoon, fox, or coyote
• Other large wild animals
• Pets that have never had rabies shots and spend time outdoors
• In the U.S., rabies occurs 4 times more in cats than in dogs.
• Outdoor animals who are sick or stray
• Dogs or cats in countries that do not require rabies shots
• In the U.S. and Canada, bites from city dogs and cats are safe.
• In the U.S., there are 2 - 3 deaths from rabies per year in humans.
