A dog bite does not necessarily mean you will get rabies; you need to clean and disinfect the wound and get rabies vaccine and rabies passive immunization preparations to prevent rabies. Dogs can transmit rabies through scratches and bites, but dog bites do not always infect people with rabies. The dog must be bitten by a dog with rabies in order to be infected, and the chance of infection is related to the size of the wound, whether or not the wound is treated, and whether or not the dog is vaccinated. Once a person is infected with rabies and develops the disease, the mortality rate is close to 100%. Therefore, after being bitten by a dog and being exposed to rabies, it is important to take preventive measures in a timely manner. First, the wound should be thoroughly cleaned and disinfected after a doctor’s consultation, and the rabies vaccine should be administered within 24 hours, with selective rabies passive immunization based on the level of exposure.
