1 Healthy dogs do not carry rabies virus and do not spread rabies. Therefore, the various instructions of rabies vaccine are clearly for people bitten or scratched by rabies or other crazy animals, not healthy dogs. If rabies occurs frequently in your place, it is another matter to vaccinate before exposure in order to prevent it.
Some people may say that the positive rate of rabies virus 10% or 30% is a "seemingly healthy" dog, which may be in the incubation period or prophase. Isn't it also said in foreign books that dogs and cats detoxify in saliva a few days before neurological symptoms appear? This statement is also difficult to explain. Even in epidemic areas, it is impossible to have such a high proportion of dogs infected with rabies virus, which cannot explain the fact that rabies is sporadic.
If you are bitten by a healthy dog or cat of your own or neighbor's house, you can rest assured that it is still healthy as usual after 10 days of observation. Some questioners said that he/she was exposed to it months or years ago, or was bitten by a dog or a cat. Later, the animal recovered, so don't worry, don't get vaccinated. If a stray dog or a dog that bit you runs away and you don't know about the dog, please go to the CDC for consultation immediately.
According to the current reliable research and documents issued by the World Health Organization, the recognized longest incubation period is 6 years. The twenty or thirty years mentioned in previous books are not accepted because of the lack of strict evidence. In the future, if rabies patients prove that their incubation period is more than 6 years, it is also possible, but it can only be recognized if there is conclusive evidence. Some people ask questions that have little to do with the incubation period, but were you bitten by an animal with rabies?
Finally, please remember the fact that there are basically no reports of rabies in domestic cities, especially big cities, and even if there are, there are only a handful. But this is not to say that dogs and people in cities have special immunity, but because the current conditions do not conform to the ecology of rabies, and in layman's terms, they do not have the conditions to spread rabies. This is one of the important principles of epidemiology. In fact, any place can create an ecology that is not conducive to rabies like a city, that is, raising dogs in the yard and getting rabies vaccine. It can be done through hard work.
