Does a cat scratch pose a serious health risk to humans?

• A. No
• B. Yes
• C. Sometimes
• D. Depends on context

Answer: (B)

Cat scratches can pose a serious health risk because they can introduce bacteria from the cat’s claws and saliva into the skin. Pasteurella multocida is a common culprit after cat scratches or bites, often causing rapid-onset redness, swelling, and cellulitis that can spread if not treated. Bartonella henselae, transmitted through scratches, can lead to cat scratch disease with fever and swollen lymph nodes; while usually mild, it can be serious for certain people, such as immunocompromised individuals. Rabies risk is a consideration with any animal exposure, though it’s more commonly linked to bites and saliva contact; tetanus is another risk if the wound is dirty and vaccination isn’t up to date. Because of these potential infections, it’s important to clean the wound promptly, watch for signs of infection, and seek medical care if symptoms develop or if the person has risk factors or uncertain vaccination history for tetanus or rabies.
