An animal bite can result in a break or tear in the skin, a bruise, or a puncture wound.
Bites - animals
Bites that result in puncture wounds are more likely to become infected. You might have a puncture wound if an animal's tooth went through your skin during the bite.
An animal bite is also more likely to become infected in those who have:
- A weakened immune system due to medicines or disease
- Peripheral artery disease
Some animals are infected with a virus that can cause rabies. Bats may spread this disease. Rabies is rare but can be deadly. If you get a rabies shot very soon after you are bitten, you can develop immunity to the disease and not get sick. For more information on this disease, see: Rabies.
Antibiotics are used to treat many animal bites, especially:
- If it involved your hands or fingers
- If a cat or monkey bit you
You may need antibiotics even if you did not need stitches or a rabies shot.
Pets are the most common cause of bites.
- Dog bites are most common.
- Cat bites are less common, but have a higher risk of infection. Cat teeth are longer and sharper, which can cause deeper puncture wounds.
- Stray animals and wild animals, such as skunks, raccoons, and bats, also bite thousands of people each year.
If you are bitten by a wild animal or an unknown pet, try to keep it in view while you notify animal control authorities for help in capturing it. They will determine if the animal needs to be impounded and checked for rabies. Any animal whose rabies vaccination status is unknown should be captured and quarantined.
Possible symptoms include:
- Break or major cuts in the skin with or without bleeding
- Crushing injuries
- Puncture-type wound
Do NOT go near an animal that may have rabies or is acting strangely or aggressively. Do NOT try to catch it yourself.
If an animal's behavior is strange, it may be rabid. Notify the proper authorities. The police can always direct you to the proper animal control authorities. Tell them what the animal looks like and where it is so they can capture it.
Call immediately for emergency medical assistance if
Call 911 if the person has been seriously wounded -- for example, if the person is bleeding significantly and it will not stop with simple first aid measures.
Call your doctor or go to a hospital emergency room if:
- The person was bitten by an unknown or wild animal.
- The person has not had a tetanus shot within the past 5 years. (If a person has not had a tetanus shot in 5 years, a tetanus shot is recommended within 24 hours of any skin break.)
- There is swelling, redness, pus draining from the wound, or pain.
- The bite is on the face, neck, or hands.
- The bite is deep or large.
- You aren't sure if the wound needs stitches.
Report the bite to the local animal control authorities, even if you don't seek professional medical care. This will allow authorities to test the animal and prevent further incidents.
- Teach children not to approach strange animals.
- Do NOT provoke or tease animals.
