The fact that a dog that bites a person does not die for a month means that the person is fine. A dog that bites a person and doesn’t die for a month means that the dog doesn’t have a contagious rabies virus in its body that can be transmitted to humans and cause them to die. There is now a ten-day observation method to determine if there is rabies infection. The ten-day observation method means that after being bitten or scratched by a suspected rabid animal (dog or cat, etc.), the animal is tethered for observation for ten days (vaccination is required before observation in rabies-endemic infected areas, and vaccination should also be administered in a timely manner in China), and if the animal remains healthy during the ten-day observation period, or if it is confirmed by reliable laboratory diagnostic techniques that the animal does not carry the rabies virus, the remaining vaccination can be stopped.
