Animal and human bite injuries in Victoria, 1998-2004.
OBJECTIVE
To describe the epidemiology of mammal (human and non-human) bite injuries in Victoria.


METHODS
Retrospective case series of injuries recorded in the Victorian Emergency Minimum Dataset (VEMD) (1998-2004) and deaths recorded in the National Coroners Information System (1 July 2000 - 1 June 2006).


METHODS
Frequency, nature and outcome of injury as a function of mammal, victim demographics and season.


RESULTS
Of 12 982 bite injuries identified in the VEMD, dogs, humans, and cats were implicated in 79.6%, 8.7%, and 7.2% of cases, respectively. Dog bite injuries were commonly sustained to the hands/wrists (31.3%) and face/head (25.4%); cat bites to the hands/wrists (67.6%) and arms (16.0%); and human bites to the hands/wrists (37.1%), arms (20.5%) and face/head (20.4%). Males comprised 73.7% and 56.3% of human and dog bite victims, respectively, while females comprised 64.1% of cat bite victims. A third of dog bite victims (33.4%) were children aged 14 years or less. Most human bite victims (79.8%) were adults aged 20-49 years, inclusive. More injuries were sustained on weekends and during the summer, 55.4% of injuries occurred in the home, and 11.6% of patients required hospital admission. Dog bites resulted in three deaths.


CONCLUSIONS
Mammal bite injuries are common and often require inpatient care. Patterns of bite injuries relate to the type of mammal involved. These epidemiological data will inform prevention initiatives to decrease the incidence of mammal bites.
