higher risk bites/wounds
- depending on individual country risk profile specific to the animal: https://www.gov.uk/government/publications/rabies-risks-by-country
- bats are always high risk
- animal with abnormal behaviour (but does not rule out)
- unprovoked bites
- unvaccinated animal (though rarely vaccinated animals have transmitted rabies)
- domestic animals should be observed for 15 days after bite for abnormal behaviour
- Broken skin - single or multiple transdermal bites, severe lacerations, or where mucous membranes or an existing skin lesion have been contaminated by the animal’s saliva or other body fluid.
- Intact skin is a barrier against infection
- bat bites in the UK may not be visible
risk assessment - details needed
- patient name, date of birth, age, address, and NHS number if possible
- date of exposure
- species and current health status of animal involved if possible
- country of exposure
- category of exposure
- site (on body) of exposure
- whether the patient is immunosuppressed or has any allergies
- any previous rabies vaccinations or immunoglobulin treatment
- weight of the patient if HRIG is being considered
