Bite Wound

Animal Bites

Consider rabies immunization and immune globulin

Human Bites

All bite episodes represent an opportunity to review Hepatitis B and tetanus immunization status.

The transmission of blood borne pathogens (Hepatitis B, C and HIV) following a bite wound in children is extremely unlikely.

Post exposure prophylaxis for Hepatitis B is recommended if the exposure to blood or body fluids was from an index case known to be Hepatitis B antigen positive and the patient has not been previously immunized against Hepatitis B.

If there is a particularly high risk situation regarding HIV transmission, a pediatric infectious diseases expert may be consulted.

Most Likely Pathogens

P. multocida (cat and dog bites)


S. aureus

Empiric Antimicrobials (Hospitalized)

Empiric Antimicrobials (Outpatient)

Usual Duration

3 to 5 days for prophylaxis

7 to 10 days for treatment

More severe cases or bite wounds associated with bacteremia may warrant longer durations. Consult Infectious Disease.
