There are faint red marks from being scratched by a dog, there should be a thorough wound cleaning and disinfection treatment, washing the wound with soap under running water, requiring a 30-minute rinse, and if disinfectant drugs such as iodophor or alcohol are available, you can use the drugs for initial disinfection of the wound and go to the hospital for further treatment of the wound. The presence of red marks indicates that there is already skin damage, an exposed wound, and a risk of rabies virus infection, so you also need to clarify whether you have a history of rabies vaccination. If you have received rabies vaccination within six months, you generally do not need to be re-vaccinated. Disinfection with iodophor or medical alcohol is sufficient, and you can also receive rabies vaccination again for insurance purposes. However, if you have not received rabies vaccine or have received rabies vaccine for more than six months, it is recommended that you promptly visit your nearest vaccination station or community clinic for timely rabies vaccination. Because rabies has a very high lethality rate, standardized preventive treatment when bitten or scratched by a dog or cat and timely rabies vaccination are critical to reduce the risk of morbidity. Try to complete rabies vaccination within 24 hours. Rabies vaccination requires five doses, one on the day of injury, one on the third day, one on the seventh day, one on the fourteenth day and one on the twenty-eighth day.
