Animal And Human Bites

Overview

Animal and human bites are wounds where teeth cut or tear the skin. They can become infected because germs from the mouth enter the wound.

Yes, bites are common. Many people visit their doctor each year for a bite.

Anyone can get bitten, but children are often bitten by pets, and people who work closely with animals have a higher risk.

Symptoms

Common symptoms

• Pain or tenderness at the bite site
• Redness or swelling
• Bleeding or a break in the skin
• Warmth around the wound
• Pus or fluid leaking
• Fever or chills

Causes

Main causes

• Dog bites (common)
• Cat bites (can be deep)
• Other animal bites like raccoons, foxes, or bats
• Human bites (from fighting or play)

Risk factors

• Young children and older adults
• Weakened immune system
• Working with animals
• Not being up to date on tetanus vaccine

When to see a doctor

See a doctor urgently if:

• Any bite that breaks the skin and is deep or on the hand, face, or joint
• You think the animal might have rabies
• A human bite that broke the skin
• Signs of infection like spreading redness, warmth, or pus

Book a routine appointment if:

• A minor bite you can clean well
• Puncture marks (small deep hole) from a pet cat or dog
• You are unsure if your tetanus shot is current

Diagnosis

A doctor will ask how the bite happened and look at the wound. They may also check your vaccination history.

Tests that may be done

• Wound culture (a swab from the bite to check for bacteria)
• Blood tests if you have signs of infection
• X-ray to check for damage to bones or a foreign object like a tooth fragment

What to expect at your appointment

The doctor may clean the wound again, apply a dressing, and possibly prescribe an antibiotic. They may also recommend a tetanus booster if needed.

Treatment

The main treatment is thorough cleaning to remove germs. Depending on the risk, the doctor may start antibiotics. You may need a tetanus shot if yours is out of date.

Self-care at home

• Wash your hands before touching the wound
• Gently rinse the bite with clean running water
• Use mild soap to wash around the wound, but don't scrub hard
• Apply pressure with a clean cloth to stop bleeding
• Cover the wound with a sterile dressing after cleaning

Medical treatments

Doctors may prescribe an antibiotic to prevent or treat infection, give a tetanus booster, or give a rabies vaccine after certain animal bites. All medicines should be used exactly as prescribed.

When is surgery considered?

For deep wounds, a doctor or surgeon may need to clean the wound in a procedure, remove damaged tissue, or close it with stitches. This is usually done under local anaesthetic.

Living with this condition

Follow your doctor's instructions on changing dressings and looking for infection. Keep the area clean and dry. If you have a bite on your hand, try to keep it raised and avoid heavy use.

Lifestyle tips

• Keep your wound covered when cleaning or sleeping
• Avoid swimming until the wound has sealed
• Don't pick at any scabs that form

Diet and exercise

Eating a healthy diet with enough protein and vitamins helps your body heal. Do light activity you feel comfortable with, but rest the affected area, especially if it is a hand or foot.

Mental health and emotional wellbeing

Being bitten can be upsetting, especially for children. It is normal to feel anxious or upset afterwards. Talk to family, friends, or a counsellor if you need help.

Prevention

Most bites can be avoided by being careful with animals, not teasing or disturbing them, and teaching children safe behaviour around pets.

Vaccines

Keeping your tetanus vaccine up to date is important. After specific animal bites, a rabies vaccine may be recommended.

Screening programmes

There is no routine screening for bites, but check your tetanus status.

Complications

If left untreated

• Infection in the skin (cellulitis)
• Abscess (a pocket of pus)
• Spread of infection to bones or joints
• Blood poisoning (sepsis)

Long-term outlook

With proper care, most bites heal well without problems. Even serious bites have a good recovery rate when treated quickly. Watch closely for infection and follow up as advised.
