🤔What is a Category III animal bite?
A Category III animal bite, according to the World Health Organization (WHO), involves one or more transdermal bites or scratches that puncture the skin, or any licks on broken skin or mucous membranes, including exposures to bats. This category indicates a higher risk of rabies transmission compared to Category I and II exposures, necessitating immediate post-exposure prophylaxis (PEP) with both rabies vaccine and rabies immunoglobulin (RIG).
Key characteristics of Category III bites:
Transdermal bites or scratches:
These are bites or scratches that break the skin, creating a puncture wound or laceration.
Licks on broken skin or mucous membranes:
Licks from an animal on open wounds or on the mucous membranes (e.g., mouth, eyes, nose) also fall under this category.
Exposure to bats:
Any contact with a bat, regardless of whether it resulted in a bite or scratch, is considered a Category III exposure.
Management of Category III Bites:
Immediate Wound Care: Thoroughly wash the wound with soap and water for several minutes.
Post-Exposure Prophylaxis (PEP):
Rabies Vaccine: Begin the PEP series as soon as possible after the exposure.
Rabies Immunoglobulin (RIG): Infiltrate RIG around the wound (if feasible) and administer the remaining dose intramuscularly.
Tetanus Vaccination: Ensure the patient's tetanus vaccination is up-to-date.
Antibiotics: Consider antibiotics to prevent bacterial infection, especially for deep wounds.
Follow-up: Monitor the patient closely for any signs of rabies and ensure completion of the PEP series.
