If you are bitten by a mouse and bleed, you should treat the wound promptly and go to the hospital for vaccination at the same time. 1. Treat the wound promptly: you should rinse the wound repeatedly with running water or soapy water, and then disinfect the wound and the skin around the wound with iodophor. 2. Go to the hospital for vaccination: Since rats themselves can carry various pathogenic microorganisms, they need to be vaccinated to prevent certain infectious diseases, such as injecting epidemiological hemorrhagic fever vaccine to prevent epidemiological hemorrhagic fever; if the wound is deeper, tetanus antitoxin should also be injected to prevent tetanus bacillus infection. Bitten by a rat and bleeding, it is recommended to seek medical attention in time and follow the doctor’s instructions for medication, mainly to prevent wound infection and prevent infectious diseases.
