Introduction
The risk of developing rabies after being scratched by a cat is very low. Statistically, the proportion of rabies cases following cat scratches is less than 0.5%. Rabies itself is a relatively rare disease; nationwide, over 90% of annual rabies cases result from dog bites without subsequent rabies vaccination. Illness following cat scratches is extremely rare, making the associated risk comparatively low.

In daily life, many people keep small pets such as cats and dogs. Interacting with them occasionally leads to injuries. So, what is the risk of developing rabies after being scratched by a cat?

What is the risk of developing rabies after being scratched by a cat?

The likelihood of developing rabies following a cat scratch is very low. Statistically, fewer than 0.5% of individuals exposed to rabies develop the disease. Rabies itself is a relatively rare condition; over 90% of annual rabies cases nationwide result from dog bites—and in most such cases, victims did not receive rabies vaccination. Rabies transmission via cat scratches is exceedingly rare, thus conferring a comparatively low risk.

In everyday practice, most individuals scratched by cats are injured by their own pet cats. Currently, the majority of domestic pets have received rabies vaccination and are maintained under relatively good hygiene conditions—further reducing the already low probability of rabies infection. Nevertheless, because rabies is invariably fatal—with a 100% mortality rate once clinical symptoms appear—caution must still be exercised even when the risk is low. Prompt and appropriate action is essential following a cat scratch. If you have had prior rabies exposure (e.g., previous bites or scratches), or if this is your second or third potential exposure, rabies vaccination is strongly recommended to prevent infection.

After being scratched by a cat or dog, immediately cleanse the wound using soap and water, iodophor, hydrogen peroxide, or normal saline.We hope this information is helpful. Wishing you good health and happiness!
