Whether or not you need to get vaccinated for a red mark scratched by your dog will depend on the situation. If the skin is broken, it is recommended to go to the hospital for rabies vaccination promptly within 24 hours after the skin lesion. Rabies is mainly transmitted by dogs in China and is an acute infectious disease. Due to the lack of effective treatment, once the disease is fatal, the mortality rate reaches almost 100%. Therefore, immediate post-exposure treatment is a necessary means of prevention. Being scratched by the dog a red mark, as long as the skin appears broken, regardless of whether there is bleeding, should be rinsed with soapy water for 20 minutes, and go to the hospital as soon as possible to play rabies vaccine. Of course, whether or not you get the disease is a matter of probability. If you are scratched by a domesticated dog, the probability of getting rabies is relatively small if you make sure that the dog has been vaccinated and has not been scratched or bitten by any other animal within six months. But if it’s a wild dog, it’s harder to guarantee safety. Whether a dog is scratched by a domesticated dog or a wild dog, it is best to get vaccinated within 24 hours.
