Rabies exposure is classified into three levels according to the mode of exposure and the degree of exposure: Contact with or feeding of animals, or licking of intact skin is considered a level I exposure. This type of exposure does not require treatment. Light bites on exposed skin, or minor scratches or abrasions without bleeding are Class II. Such wounds should be rinsed with soap and running water for at least fifteen minutes and then disinfected with iodophor and given rabies vaccine as soon as possible. Single or multiple penetrating skin bites or scratches, or broken skin licked, or open wounds or contaminated mucous membranes are Grade III. If the person is confirmed to be a Grade II exposed person and is immunocompromised, or if the Grade II exposure is located on the head and face and the injured animal is not determined to be healthy, dispose of it according to Grade III exposure. In cases of Grade III exposure, wounds should be rinsed with soapy running water for at least fifteen minutes and then disinfected with iodophor, and rabies vaccine should be administered as soon as possible, along with local rabies immunoglobulin injections. Rabies immunoglobulin (20 IU/kg body weight) is injected locally by infiltration and intramuscularly in the bite wound.
