Rabies Prophylaxis for Rodent Bites

Risk Assessment

• The Centers for Disease Control and Prevention notes that small rodents, including rats, are extremely low-risk species for rabies transmission, even in areas with endemic wildlife rabies 1
• According to CDC data, woodchucks accounted for 93% of rabies cases among rodents from 1990-1996, with rats not significantly represented in these statistics 2, 1

Appropriate Management

• Immediate and thorough washing of all bite wounds with soap and water for 15 minutes is the most important first step for any animal bite, as recommended by medical guidelines 1
• Apply a virucidal agent such as povidone-iodine solution to the wound after washing, as suggested by medical guidelines 1

Important Distinctions Between Animal Species

• Unlike rats, bats are documented rabies reservoirs in all 49 continental United States and require different management 3
• Wild terrestrial carnivores, such as raccoons, skunks, foxes, and coyotes, are high-risk species for rabies transmission and typically require immediate prophylaxis after a bite, according to the CDC 2, 4

Common Pitfalls to Avoid

• The CDC recommends not confusing the management of rat bites with that of high-risk species like bats or wild carnivores, which often do require rabies prophylaxis 2, 3
