Animal and human bites may cause puncture wounds, cuts, scrapes, or crushing injuries. Most animal and human bites cause minor injuries, and home treatment is usually all that is needed to care for the wound.
Most animal bites occur in school-age children. The face, hands, arms, and legs are the most common sites for animal bites. Since most bites occur in children, be sure to teach children to be careful around animals and that an animal could hurt them. Young children should always be supervised around animals.
Dog bites occur more than any other animal bite and are most frequent in the summer months. The dog is usually known to the person, and most injuries result from the dog being teased or bothered while eating or sleeping. Boys are bitten about twice as often as girls. The arms, head, and neck are the most likely areas to be bitten in children.
Cat bites usually cause deeper puncture wounds than dog bites and have a high risk of bacterial infection because they can be hard to clean adequately.
Exotic pet bites, such as from rats, mice, or gerbils, may carry illnesses, but rabies is not usually a concern. The bites from some pets, such as iguanas, are at risk for infection but do not carry other serious risks.
Livestock, such as horses, cows, and sheep, have powerful jaws and can cause crushing bite injuries. Infection, tetanus, and rabies are possible risks.
Wild animal bites may occur while hunting, camping, or hiking. Infection, tetanus, and rabies are possible risks.
Adult bites that cause a wound to the hand can be serious. A clenched fist striking another person in the mouth and teeth can cut or puncture the skin over the knuckles. This is commonly called a "fight bite." Underlying tissues may be damaged, and an infection can develop.
Bites from children are:
When you have a bite:
Check your symptoms to decide if and when you should see a doctor.
Many things can affect how your body responds to a symptom and what kind of care you may need. These include:
You have answered all the questions. Based on your answers, you may be able to take care of this problem at home.
Symptoms of infection may include:
Pain in adults and older children
Pain in children under 3 years
It can be hard to tell how much pain a baby or toddler is in.
With severe bleeding, any of these may be true:
With moderate bleeding, any of these may be true:
With mild bleeding, any of these may be true:
Symptoms of difficulty breathing can range from mild to severe. For example:
You may need a tetanus shot depending on how dirty the wound is and how long it has been since your last shot.
Rabies may be a concern after an animal bite if:
To clean a wound well:
If a chemical has caused a wound or burn, follow the instructions on the chemical's container or call your provincial poison centre to find out what to do. Most chemicals should be rinsed off with lots of water, but with some chemicals, water may make the burn worse.
Certain health conditions and medicines weaken the immune system's ability to fight off infection and illness. Some examples in adults are:
Based on your answers, you may need care soon. The problem probably will not get better without medical care.
Based on your answers, you may need care right away. The problem is likely to get worse without medical care.
Based on your answers, you need emergency care.
or other emergency services now.
Put direct, steady pressure on the wound until help arrives. Keep the area raised if you can.
Based on your answers, you need emergency care.
Minor animal and human bites usually can be treated at home. If you do not have an increased chance of getting an infection, do not have other injuries, and do not need treatment by a doctor or a tetanus shot, you can clean and bandage a bite at home.
Stop the bleeding
with direct pressure to the wound.
After you have stopped the bleeding, check your symptoms to determine if and when you need to see your doctor.
Clean the animal or human bite as soon as possible to reduce the chance of infection and scarring.
Some bites cause only bruising (contusions) at the bite site but do not break the skin. These bites usually do not become infected.
Determine whether your bite needs to be treated by a doctor. Bites may need to be closed with sutures, staples, or skin adhesives so that they won't leave a large scar. Bites to the hand are not usually closed because closing the bite wound may increase your chance of having an infection. Cat bites are rarely closed because they are usually no larger than a puncture.
Your doctor will tell you how to take care of your stitches or staples and when to return to have them removed. Skin adhesives usually do not need to be removed, but your doctor may wish to see you to check on the wound. Be sure to carefully follow your doctor's instructions. If you are unsure of how to care for your wound or have questions, call your doctor for instructions.
Most bites heal well and may not need a bandage. You may need to protect the bite from dirt and irritation. Be sure to clean the bite thoroughly before bandaging it to reduce the risk of infection occurring under the bandage.
An ice or cold pack may help reduce swelling and bruising. Never apply ice directly to a wound or the skin. This could cause tissue damage.
Elevate the injured area on pillows while applying ice and anytime you are sitting or lying down. Try to keep the area at or above the level of your heart to reduce swelling.
Talk to your child's doctor before switching back and forth between doses of acetaminophen and ibuprofen. When you switch between two medicines, there is a chance your child will get too much medicine.
Many provinces require that animal control authorities be notified of animal bites. Even if your provincial law does not require you to report animal bites, you may wish to call animal control to report the bite. They can help you determine whether the animal that bit you:
If you are unable to find a phone number for animal control in the front pages of the telephone book, contact the police or sheriff's office for the number.
