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
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

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

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.
After you have stopped the bleeding, check your
symptoms to determine if and when you need to see your

Clean the animal or human bite as
soon as possible to reduce the chance of infection and scarring.
Wash the wound for 5 minutes with large amounts
of cool water and soap (mild dishwashing soap, such as Ivory, works well). Some nonprescription products are available for wound
cleaning that numb the area so cleaning doesn't hurt as much. Be sure to read
the product label for correct use.
Don't use rubbing alcohol,
hydrogen peroxide, iodine, or Mercurochrome, which can harm the tissue and slow
Some bites cause only bruising (contusions) at the bite site
but do not break the skin. These bites usually do not become infected.
Stitches, staples, or skin adhesives (also called liquid skin)
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

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.
Consider applying a bandage
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.
Select the bandage carefully. There are many
products available. Do not use liquid skin bandages and moisture-enhancing
bandages unless your doctor tells you to. These types of dressings may seal in
bacteria that could cause an infection.
If you use a cloth-like
bandage, apply a clean bandage when your bandage gets wet or soiled. If a
bandage is stuck to a scab, soak it in warm water to soften the scab and make
the bandage easier to remove. If available, use a nonstick dressing. There are
many bandage products available. Be sure to read the product label for correct
signs of infection. If an infection develops under a
bandage, a visit to your doctor may be needed.
ointment, such as polymyxin B sulfate (for example, Polysporin) or bacitracin,
will keep the bandage from sticking to the wound. Apply the ointment lightly to
the wound. Antibiotic ointments have not been shown to improve healing. Be sure
to read the product label about skin sensitivity. If a skin rash or itching
under the bandage develops, stop using the ointment. The rash may be caused by
allergic reaction to the ointment.

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.
