What is the recommended treatment for a cat bite to prevent rabies transmission?

From the Guidelines

For a cat bite with potential rabies exposure, immediately wash the wound thoroughly with soap and water for at least 15 minutes, then apply an antiseptic like povidone-iodine, and seek medical attention promptly to initiate post-exposure prophylaxis (PEP) as soon as possible, which typically includes rabies immune globulin (RIG) and a series of rabies vaccine doses, as recommended by the most recent guidelines 1.

Initial Wound Care

• Wash the wound with soap and water for at least 15 minutes.
• Apply an antiseptic like povidone-iodine.

Post-Exposure Prophylaxis (PEP)

• PEP should include both passive antibody (RIG) and vaccine for individuals who have never been previously vaccinated for rabies, regardless of the interval between exposure and initiation of prophylaxis 1.
• For previously vaccinated individuals, only vaccine is needed, without RIG.
• The vaccine series typically consists of four doses given on days 0,3,7, and 14 after exposure.
• For previously vaccinated individuals, only two vaccine doses (days 0 and 3) are needed.

Additional Considerations

• The wound may also require antibiotics to prevent bacterial infection, such as amoxicillin-clavulanate (875/125 mg twice daily for 5-7 days).
• Observing the cat for 10 days, if possible, can help determine if rabies transmission is unlikely if the cat remains healthy.
• Rabies is nearly always fatal once symptoms appear, making immediate treatment crucial to neutralize the virus before it reaches the brain.

Management and Prevention

• Reporting the incident to the local health department is essential for managing the risk of rabies transmission from other biting animals 1.
• Prior vaccination of the animal does not preclude the necessity for euthanasia and testing if the period of virus shedding is unknown for that species.

From the FDA Drug Label

The essential components of rabies post-exposure prophylaxis are wound treatment and, for previously unvaccinated persons, the administration of both human rabies immune globulin (RIG) and vaccine. Thoroughly wash and flush all bite wounds and scratches immediately or as early as possible (for about 15 minutes, if possible) with soap or a cleansing agent and copious amounts of water. Administer post-exposure antirabies vaccination with rabies vaccine in addition to administering Rabies Immune Globulin (RIG) Dogs, cats, and ferrets: Healthy and available for 10 days observation: Persons should not begin prophylaxis unless animal develops clinical signs of rabies.

The recommended treatment for a cat bite to prevent rabies transmission is:

• Immediate wound cleaning: Thoroughly wash and flush the bite wound with soap and water for about 15 minutes.
• Post-exposure prophylaxis: Administer both human rabies immune globulin (RIG) and vaccine, unless the cat is healthy and available for 10 days observation.
• Vaccination: Administer post-exposure antirabies vaccination with rabies vaccine.
• Consult public health officials: If the cat's vaccination status is unknown or if it is not available for observation, consult public health officials for guidance on post-exposure prophylaxis 2.

From the Research

Cat Bites and Rabies Transmission

• Cat bites can potentially transmit rabies, although the risk is generally considered lower than that of dog bites 3, 4.
• The management of cat bites should include an assessment of the risk of rabies transmission, as well as the risk of other infections such as Pasteurella multocida 3, 4.

Recommended Treatment

• The recommended treatment for cat bites to prevent infection includes wound cleaning and the use of antibiotics such as amoxicillin-clavulanate 3, 5.
• However, there is no evidence that prophylactic antibiotics are effective in reducing the risk of infection after cat bites, except in the case of hand bites 5.
• Post-exposure prophylaxis (PEP) for rabies, including immediate wound washing, rabies immunoglobulin administration, and vaccination, is essential in preventing rabies transmission after a cat bite 6.

Rabies Awareness and Prevention

• Education about the occurrence of rabies in cats is crucial in reducing the associated risks to public health 7.
• Routine vaccination of cats against rabies is recommended to reduce the risk of transmission to humans 7.
• It is essential to consult a healthcare professional or a rabies prevention center as soon as possible after a cat bite to assess the risk of rabies transmission and receive appropriate treatment 6.
