A scratch from a dog with a mark, but no bleeding, is not a particularly serious case of possible transmission of rabies to a person. However, depending on the level of rabies exposure, this would also be judged as a secondary exposure, and secondary exposure is also potentially infectious to human rabies, so appropriate precautions should also be taken. It is not necessary to inject rabies serum or anti-rabies human immunoglobulin, but it is necessary to inject rabies vaccine, the complete vaccine requires five injections, the first rabies vaccine is recommended to be injected on the day after scratching or the next day, and the time interval between the first injection and scratching is not recommended to exceed 24 hours. Although it is unlikely that rabies can be transmitted to humans, since there is a risk, rabies vaccination is recommended to do this as a precaution.
