Dogs are the animals with the highest risk of spreading rabies, but it is not certain that you will get rabies if you are bitten and scratched by a dog, depending on the immunization status and the level of the wound. Rabies is vaccine immunizable, and dogs that have completed full immunization will not transmit rabies, nor will people who have completed full immunization contract rabies, independent of the degree of the wound. In reality, it is often difficult to confirm whether an animal has completed full immunization with the rabies vaccine, so the risk of infection is determined primarily by the extent of the wound. Rabies is primarily transmitted through saliva, the risk of infection from scratches is much lower than from bites, and the risk of transmission is much lower in pet dogs than in stray dogs. Depending on the depth of the wound and the exposure, there are three levels: intact skin contact with animals and animal secretions is a Class I exposure. Those judged to be Class I exposed are generally not infected and do not need to be disposed of. Scratches, bites or wounds that have not yet healed and come into contact with animals and secretions without obvious bleeding are classified as Class II exposure. Those who are judged to have Class II exposure are at risk of infection and should have their wounds treated immediately and receive rabies vaccination. Scratches and bites with obvious bleeding and fresh wounds or mucous membranes in contact with animals and secretions are Class III exposures. Those judged to have a Class III exposure are at high risk of infection and should have their wounds treated immediately and given a passive rabies immunization preparation followed by rabies vaccination. Generally speaking, if the skin is broken and not bleeding, it is a Class II exposure, and if the bite is scratched but the skin is not broken, it is a Class I exposure. If you are not sure if the skin is broken, you can use alcohol wipes to distinguish between Class I or Class II wounds; no pain is a Class I exposure and pain is a Class II exposure. To distinguish between Class II or Class III exposure can be done by whether there is obvious bleeding at that time. Wounds without bleeding, a small amount of blood oozing and bleeding after squeezing belong to Class II exposure, and obvious bleeding or full skin rupture belongs to Class III. After determining the level of exposure, the physician at the rabies prevention and disposal clinic should immediately perform wound treatment as needed; after informing the exposed person of the danger of rabies and the disposal measures that should be taken and obtaining informed consent, the corresponding disposal measures should be taken. Therefore, whether you will get rabies after being bitten depends on both the immunization and the wound, because in reality it is difficult to ensure that all animals are vaccinated, and human-initiated rabies vaccination is the most effective means of prevention.
