Treatment for Category 2 Animal Bite

Immediate Wound Management

The World Health Organization recommends performing immediate and thorough wound cleansing with soap and water or sterile normal saline, as this is the single most important intervention for preventing rabies and bacterial infection, for individuals with Category 2 animal bites 1, 2
The Centers for Disease Control and Prevention suggests using copious irrigation with water or dilute water povidone-iodine solution to mechanically remove debris and reduce bacterial load in patients with Category 2 exposures 1
The World Health Organization advises against aggressive debridement or tissue damage during cleansing—gentle irrigation is sufficient for Category 2 exposures, which are defined as nibbling of uncovered skin or minor scratches/abrasions without bleeding 1
The Centers for Disease Control and Prevention recommends that Category 2 wounds should be left open to heal by secondary intention, and not sutured, to promote proper healing and minimize infection risk 2

The World Health Organization recommends administering 5 doses of rabies vaccine (HDCV or PCECV) intramuscularly on days 0, 3, 7, 14, and 28 for individuals with Category 2 animal bites, with the vaccine given in the deltoid area for adults and the anterolateral thigh for children 1, 2
The Centers for Disease Control and Prevention advises against administering rabies vaccine in the gluteal area, as this results in lower neutralizing antibody titers, and instead recommends the deltoid area for adults and the anterolateral thigh for children 2
The World Health Organization recommends beginning vaccination as soon as possible after exposure, as this is a medical urgency, and not delaying it while waiting for animal observation results, which should be discontinued only if the animal remains healthy after 10 days of observation 1

The Centers for Disease Control and Prevention recommends administering tetanus toxoid 0.5 mL intramuscularly if vaccination status is outdated or unknown, with a booster given if more than 10 years since last dose for clean minor wounds, and more than 5 years since last dose for contaminated wounds 1, 2

The World Health Organization warns against confusing Category 2 with Category 3 exposures, as Category 3 requires both vaccine and immunoglobulin, and delaying rabies vaccination while waiting for animal observation results, which can increase the risk of rabies transmission 1, 2
The Centers for Disease Control and Prevention advises against using the gluteal area for vaccine administration, as this is a documented cause of vaccine failure, and recommends the deltoid area for adults and the anterolateral thigh for children 2
