What is the chance of getting infected after being scratched by a dog?

There is no way to calculate the specific data on the incidence of being scratched by a dog. If it is scratched by a sick dog, the chance of infection is still relatively high. Please note that it is a "sick dog" "Not everyone who is bitten by a dog will get rabies. If the dog that bites a person does not carry the rabies virus, then the wound can be disinfected. If you cannot determine whether the dog that injured someone is healthy, you should promptly inject rabies vaccine for prevention after treating the wound.
