A minor scratch from a dog’s paw is required for rabies vaccination. Rabies is caused by a viral infection, and although the virus is generally more present in the saliva and tissue fluid of the dog and has a relatively short survival time on the nail, it is difficult to tell if the dog has licked the nail before scratching the person. Once a dog carries rabies virus, there is a high probability that the paws also have the virus present. At this point, if scratched, the chances of contracting rabies virus are high, so rabies vaccination is needed for prevention. After being slightly scratched by a dog’s paw, you can use a cotton swab soaked in alcohol to wipe on the scratch, and if there is a stinging pain, it can be judged that there has been a case of skin breakdown, which belongs to rabies virus secondary exposure; if there is bleeding from the wound, it belongs to tertiary exposure, and both cases need rabies vaccination. Before going to the hospital for rabies vaccination, the wound should be treated urgently by first rinsing the wound with soapy water or running water for 20 minutes, then disinfecting the wound with iodophor or alcohol, and keeping the area around the wound dry after disinfection is completed to avoid touching water again. The best time to receive rabies vaccination is within 24 hours after being scratched by a dog, and the vaccination method is commonly a 5-dose procedure, which is administered on the same day, as well as on the 3rd, 7th, 14th, and 28th days, respectively; in addition, there is a 4-dose vaccination method approved in China, which is 2 doses on day 0 and 1 dose on the 7th and 21st days. If it is clear that the dog that caught the person has been infected with rabies virus, it is also necessary to use rabies human immunoglobulin or anti-rabies serum as soon as possible to achieve rapid passive immunization.
