If the patient is scratched by a cat, it is recommended to go to the hospital for injection in time. In this case, it is necessary to prevent rabies virus infection in time, so it is necessary to carry out rabies virus vaccination at this time to avoid leading to rabies virus infection. Because after being scratched by a cat, if the rabies virus exists in the cat’s body, it may enter the patient’s blood circulation through the scratches, and if timely prevention of rabies virus infection is not carried out at this time, it may lead to infection, thus causing the patient to develop the symptoms of rabies, and in serious cases, it may jeopardize the patient’s life, resulting in the patient’s death. Rabies virus is normally found in oral saliva, so if the cat usually licks its own paw with its tongue, it may lead to the rabies virus in the saliva to the paw, and then if the patient is scratched by the cat’s paw, it may cause the virus to enter the patient’s blood circulation, which may cause the patient to become infected. Therefore, this time must be timely inoculation to avoid the infection of the situation.
