A slight break in the skin scratched by a cat’s teeth requires rabies vaccination. Since the cat’s saliva may contain rabies virus, the virus may enter the human body through the broken mucous membrane and cause the human body to be infected with rabies virus after being scratched by the cat’s teeth. After being scratched by a cat’s teeth and breaking the skin, you need to use a lot of water or soapy water to rinse the local wound, disinfect it with iodophor, and then go to the nearby vaccination clinic as soon as possible to receive the full rabies vaccination. Rabies is a fatal disease, and the mortality rate after the onset of the disease is close to 100%. Therefore, once bitten by an animal that may have rabies or is not sure if it is poisonous, you should be vaccinated against rabies immediately. Avoid drinking alcohol, strong tea and other stimulating foods and staying up late during the rabies vaccination period to avoid affecting the production of antibodies or causing adverse reactions.
