Dog bites with broken skin, bleeding, and exposed wounds require rabies vaccination, but if the skin at the bite is intact and unbroken, no vaccination is needed. The need for rabies vaccine is determined by the nature of the rabies exposure and the severity of the bite. Secondary exposure is when the patient’s skin is bitten, broken and bleeding, and the broken area comes into contact with dog secretions or feces, in which case the rabies vaccine needs to be administered within 24 hours after disinfecting and cleaning the area. Third-degree exposure is when the patient has one or more bites or scratches, the broken skin comes into contact with dog saliva, and the mucous membranes of the human body are contaminated, which needs to be sterilized and then injected with rabies vaccine immediately. First-degree exposure is contact with an animal, skin intact without skin lesions, intact skin in contact with animal secretions or feces, at this time do not need to inject rabies vaccine. After being bitten by a dog, you need to go to the CDC in time to consult whether to inject the vaccine or not, and not to delay carelessly.
